For example, you might want to change your score or your name during the game.\n\nWhen responding to a chat command event we can add **arguments** to pass variable values in when running the command.\n\nWhen we talk about arguments in JavaScript, we're talking about **values that we pass into a function.** A function is like a set of instructions that we can reuse over and over again. **We pass in arguments to a function to give it different inputs,** and then the function can do something with those inputs and give us an output.\n\n## Step 2\n\nTo practice this, we are going to use an on chat command to run the code.  We will add a chat command which allows us to jump a number of blocks on the Y axis - the number of blocks to be jumped can be provided during the game.\n\nTo code a chat command, type the following code. \n\n    player.onChat(\"\",  function  ()  {\n    })\nIn the space below, type an on chat command with the word jump inside the quotation marks. \n\n#### ~ tutorialhint\n\n```javascript\nplayer.onChat(\"jump\",  function  ()  {\n\n})\n\n```\n\n## Step 3\n\nTo add an argument the on chat command, type the variable name in the parentheses next to the word function.  We are going to use a variable called Y.  Type Y in the parentheses following the word function. \n#### ~ tutorialhint\n\n```javascript\nplayer.onChat(\"jump\",  function  (Y)  {\n\n})\n\n```\n\n## Step 4\n\nNext, we want to add to the code what we want to happen when the code runs.  We want the player to jump to the Y position that the argument will set.  First, add the player teleport code into the chat command (between the curly brackets).  Then change the Y coordinate to the variable Y. \n\nThe player teleport code is \n\n    player.teleport(pos(0,  0,  0))\n    \n#### ~ tutorialhint\n\n```javascript\nplayer.onChat(\"jump\",  function  (Y)  {\n\nplayer.teleport(pos(0,  Y,  0))\n\n})\n```\n\n## Step 5\n\nIn this activity, we chose a variable that we have not yet declared. \nIf we would have chosen an existing variable the value of that variable would have been set to the value provided in the chat command.  However, because we chose a new variable, we will need to add the value in the chat command when we run the code.  Follow the instructions on the next step to test the code. \n\n## Step 6 @unplugged\n\nTo test your code:\nOnce you have fully read this step click the Green Ok button below to close this window to return to the tutorial to perform the below steps to test your code.\n\n1.

Move down the stairs into the jump area. \n1.  Open the chat by pressing the letter T on your keyboard. \n2. Type jump 10.  \n3. Your player should jump 10 blocks into the air and return to the ground. \n4. You can try other arguments by trying different numbers after the word jump in the chat. (Don't go more than 29 or you will leave the jump zone.)\n5.

Boolean Variables are often used in control statements such as 'if' statements, 'while' loops, and 'for' loops to **make decisions based on whether a condition is true or false.** \n\nFor example, the following code used a Boolean variable 'is_raining' to decide whether or not to bring an umbrella. \n\n    let is_raining =  true\n    if  (is_raining)  {\n\t    player.say(\"It's raining.

For example, we learned in the last lesson that the \"+\" operator can be used in both string concatenation, and addition of numbers, so when you use the \"+\" operator with both a string and a number, JavaScript will convert the number to a string. \n\nFor Example:\n\n**Concatenation of string and number**\nEnter the code below and take note of the output. \n\n    let result= \"Hello\" + 35\n    player.say(result)\n  \n **Step 3**   \n \n   **Addition of a string and number**\n   Enter the code below and take note of the output. \n    \n    let sum = \"3\" + 5\n    player.say(sum)\n    //output 35\n\n**Step 4**\n\nExplicit Type Conversion (type casting) is where you explicitly convert one data type to another using functions or operators, so you can ensure a specific data type before using that value.\n\nFor Example:\n\n**Convert a string to a number**\n\n   ```javascript \n    let num= parseInt(\"35\")\n    player.say(num)\n\n**Convert a number to a string**\n\n    let str= String(35)\n    player.say(str)\n\n**Convert a Boolean to a string**\n\n    let bool= true;\n    player.say(str)\n\n**Convert a string to a Boolean**\n\n    let bool2= Boolean(\"Hello\")\n    player.say(bool2)\n\n**Step 5**\nIn the space below, practice converting a number of your choice to a string, and say the answer in the chat.\n\n\n\n\n","README.md":"\n> Open this page at [https://codinginminecraft.github.io/coding-in-minecraft-expert-javascript/](https://codinginminecraft.github.io/coding-in-minecraft-expert-javascript/)\n\n## Use as Extension\n\nThis repository can be added as an **extension** in MakeCode.\n\n* open [https://minecraft.makecode.com/](https://minecraft.makecode.com/)\n* click on **New Project**\n* click on **Extensions** under the gearwheel menu\n* search for **https://github.com/codinginminecraft/coding-in-minecraft-expert-javascript** and import\n\n## Edit this project ![Build status badge](https://github.com/codinginminecraft/coding-in-minecraft-expert-javascript/workflows/MakeCode/badge.svg)\n\nTo edit this repository in MakeCode.\n\n* open [https://minecraft.makecode.com/](https://minecraft.makecode.com/)\n* click on **Import** then click on **Import URL**\n* paste **https://github.com/codinginminecraft/coding-in-minecraft-expert-javascript** and click import\n\n## Blocks preview\n\nThis image shows the blocks code from the last commit in master.\nThis image may take a few minutes to refresh.\n\n![A rendered view of the blocks](https://github.com/codinginminecraft/coding-in-minecraft-expert-javascript/raw/master/.github/makecode/blocks.png)\n\n#### Metadata (used for search, rendering)\n\n* for PXT/minecraft\n<script src=\"https://makecode.com/gh-pages-embed.js\"></script><script>makeCodeRender(\"{{ site.makecode.home_url }}\", \"{{ site.github.owner_name }}/{{ site.github.repository_name }}\");</script>\n","main.blocks":"<xml xmlns=\"https://developers.google.com/blockly/xml\"><block type=\"minecraftOnChat\" id=\"j@KSt9^6l,G6f)[{4xh0\" x=\"0\" y=\"0\"><mutation xmlns=\"http://www.w3.org/1999/xhtml\" numargs=\"0\"></mutation><value name=\"command\"><shadow type=\"text\" id=\"(/R{DJ@Q*;G[`1ceN0@Q\"><field name=\"TEXT\">run</field></shadow></value></block></xml>","main.ts":"player.onChat(\"run\", function () {\n\t\n})\n","Lesson2/2.1/2.1.md":"## Step 1 @unplugged\n\nIn JavaScript, operators are keywords or symbols that are used to perform various operations on values.

These devices connect to the internet through an Internet Service Provider (ISP) using technologies like Wi-Fi, Ethernet cables, or cellular networks.\n\n## Step 2 @unplugged\n\nWhen you send or receive information over the internet, it is passed through a data stream which contains chunks of data.  This data is in packets. **Each packet contains a piece of the information you want to share, along with the necessary instructions to reach its destination.** These packets travel through the internet separately. They may arrive in order, out of order, or not at all.  When they arrive, they are reassembled. \n\n## Step 3 @unplugged\n\n**The protocols used in the Internet are open, which allows users to easily connect additional computing devices to the Internet.** IP, TCP, and UDP are common protocols used on the Internet.\n\n**Every device connected to the internet has a unique identifier called an IP (Internet Protocol) address.** It is similar to a phone number or an address that helps computers find and communicate with each other. IP addresses are like digital labels that allow data to be sent and received between devices\n\n## Step 4 @unplugged\n\n**Routers are special devices that help direct data packets across the internet.** Think of them as traffic cops that decide the most efficient path for the packets to reach their destination. They examine the IP addresses on the packets and forward them to the next router until they reach their intended destination. Routing on the Internet is usually dynamic; it is not specified in advance.\n\n## Step 5 @unplugged\n\nNow that you've learned more about the Internet, go to the next NPC to help our Programming team with operators. ","Lesson2/2.1/2.2.md":"## Comparison Operators\n\n## Step 1 @unplugged\n\nIn JavaScript, comparison operators are used to compare values, and return a Boolean value(true or false). Here are some examples of the different comparison operators in JavaScript:\n\n1. **equal to(==)** : The equality operator will check if two values are equal.\n2. **not equal to (!=)** : the inequality operator checks if two values are NOT equal.\n3. **strict equal to (===)** : the strict equality operator checks if two values are equal by comparing both the value and the data type.\n4. **strict not equal to (!==)**: the strict inequality operator checks if two values are not equal by comparing both the value and the data type.\n5. **greater than (>)** : the greater than operator check if the left operand is greater than the right operand\n6. **less than (<)** : the less than operator checks if the left operand is less than the right operand\n\nTypically, comparison operators are used in conditional statement and comparisons to make decisions based on certain conditions. The goal of comparison operators is to return a Boolean value of true or false, to make decisions. \n\n## Step 2\n\nLet's use a few different comparison operators and see what happens. For this activity, we will use the player.say command. First, have the player say (3>5) to test out the greater than operator. \n\n#### ~ tutorialhint\n```javascript\n    player.say(3>5)\n```\n\n## Step 3\nTest your code by pressing the green button. You should see a Boolean response in the chat. Return to this coding screen once you have successfully ran your code. \n\n\n## Step 4\n\nGreat job. Your player should have said \"false\" when testing if three was great than 5. \nNext, let's test a less than operator with the same numbers, in the same order, and repeat the process of checking for a Boolean response after you write your code.\n\n#### ~ tutorialhint\n```javascript\n    player.say(3<5)\n```\n\n\n## Step 5 \n\n\nAwesome! You should have seen that the player gave back a 'true' Boolean response, showing that 3 in less than 5. \n\nLastly, check an equal to operator with numbers of your choice. Once tested, you should see a Boolean response in the chat depending on the numbers that you put!\n\n\n## Step 6 @unplugged\n\nNow run the code by clicking the **green start button** in the bottom right of the MakeCode screen.\n\n\n![alt text](https://expertjs.codingcredentials.com/Lesson1/1.1/1.JPG?raw=true  \"Start\")\n \n\nYou will know your code is correct when you see the text \"What a nice day\" appear on your screen.\n \n\nWhen your code works as expected move on to the next activity.  \n\n## Step 7\n\n  \n\nIf it does not work as expected, try to fix and test again.\n\n  \n\nNow that you have learned about arithmetic operators, continue to the next activity to learn about comparison operators. \n\n","Lesson2/2.1/2.3.md":"**Logical Operators**\n### @explicitHints true\n\n  \n\n## Step 1- Learn More\n\n  \n\n**Logical Operators** are used to manipulate or combine Boolean (true or false) values. In JavaScript, we mostly use three logical operators:\n\n1. AND(&&)\n\n2. OR(||) *This key is the \"pipe\" symbol that shares with the back slash above the enter key on your keyboard*\n\n3. NOT(!)\n\nThese logical operators perform operations on expressions, and will return Boolean values as a result. Continue on to see some of these operators in action.\n\n## Step 2\n\nThe AND (&&) Operator will return true **only if both operands are true**, otherwise it will return false. Using the temple below, let's test an AND operator by comparing two values from the variables below.

Let's use the same variables as before, and test the OR operator. Enter the same variables as before in the space below, then continue on.\n\nRemember, the (||) key is (Pipe symbol) is located in the same key as the backslash key, above the enter key on the keyboard. \n\n#### ~ tutorialhint\n\n```javascript\n\n    let x=5\n    let y=7\n    let z=10\n   ```\n\n\n## Step 5\n\nAfter the variables, let's add in an OR operator after a player.say command to test the Boolean response. Add a player.say followed by (operand1 || operand2) and choose how you would like to compare.\n\n#### ~ tutorialhint\n```javascript\n\n    let x=5\n    let y=7\n    let z=10\n    player.say(x <y || z>x)\n   ```\n\n## Step 6\n\nNow run your code by pressing the green start button, and return to this screen.\n\n## Step 7\nYou should have gotten back a Boolean in the chat of True or False, depending on the comparisons you chose. \n\nFinally, the NOT(!) operator negates a Boolean value. This means that if a comparison would return false, adding the NOT operator would return True, and vice versa. \n\nContinue on to the next NPC.\n\n","Lesson2/2.1/2.4.md":"# Expert Coding using JavaScript - Lesson 2.4\n\n### @explicitHints true\n\n  \n\n## Step 1 @unplugged\n\n  \n\nAssignment Operators are an imperative aspect of writing lines of code in JavaScript.

It involves creating a series of rules, conditions, and actions that dictate what a program should do when it is executed.\n\nThe logic of a program typically involves the use of conditional statements. **Conditional statements**, also known as \"if-statements,\" are used in coding to **make decisions based on certain conditions**. These statements work by checking if a specific condition is true or false, which is represented by a Boolean expression. Depending on whether the condition is true or false, different statements are executed in a specific order. \n\n## Step 2 @unplugged\n\nIn JavaScript you have a variety of conditional statements.  One of which is the **If Statement**.  \nIf Statements check to see if a condition is true or false and execute code if the condition is true. If Statements check to see if a condition is true or false and execute code if the condition is true. If Statements check to see if a condition is true or false and execute code if the condition is true.  \nBelow is an example of an If statement that checks to see if the variable for playerAge is greater than or equal to 13.  If the condition is true, the player will say \"You can play.\" \n\n    let playerAge =  13\n    if  (playerAge >=  13)  {\n\t    player.say(\"You can play!\")\n\t    }\n\nNotice the indentation in the code above. In JavaScript, indentation is not required, however, we will be using it to indicate the structure and hierarchy of our code.  In the example above, we have indented the player.say portion of the if-statement so the we can better understand that portion of the code is what will run if the conditional is true. \n\n## Step 3 @unplugged\n\nWe use  **logic conditions** in JavaScript conditional statements. Here are some examples of these conditions. \n-   Equals:  a == b\n-   Not Equals:  a != b\n-   Less than:  a < b\n-   Less than or equal to:  a <= b\n-   Greater than:  a > b\n-   Greater than or equal to:  a >= b\n\nIn our example below, you will see again that we used the condition of greater than or equal to. \n\n    let playerAge =  13\n    if  (playerAge >=  13)  {\n\t    player.say(\"You can play!\")\n\t    }\n\n## Step 4\n\nNow it is your turn to write an if statement.

Fault tolerance is what allows us to keep using the network even when these failures happen.\n\n## Step 2 @unplugged\n\n**Redundancy:** The Internet has been designed with redundancy, which means there are **multiple paths for data to travel from one point to another.** This redundancy helps ensure that if one path or connection fails, data can still be routed through alternative paths.

We want our aquarium to be in the middle of the 5x5 area we cleared, but we only want it to be 3x3.  \n\nWe will need to move the agent into the correct spot to start building.  He will need to turn right move forward by 1, and then turn right again, and then forward by 1 again. \n\nCreate a new chat command called move and add this code in that chat command. \n\n#### ~ tutorialhint\n```javascript\nplayer.onChat(\"move\",  function  ()  {\n\tagent.turn(RIGHT_TURN)\n\tagent.move(FORWARD,  1)\n\tagent.turn(RIGHT_TURN)\n\tagent.move(FORWARD,  1)\n})\n```\n\n## Step 3\n\nNext, we want to build the base of the aquarium. Create a new chat command named base.  Inside the chat command, we will add an if / else statement that has the agent check his inventory in slot 1.\n\nIn Minecraft, you can code the agent to test for certain items in their inventory.  The code for this is below. \n\n    agent.getItemDetail(1)  ==  GLASS\n\n#### ~ tutorialhint\n```javascript\nplayer.onChat(\"base\",  function  ()  {\n\tif  (agent.getItemDetail(1)  ==  GLASS)  {\n\n\t}  else  {\n\n\t}\n})\n```\n\n## Step 4\n\nContinue building the if / else statement.  If it does have glass in it's inventory, the agent will then build the base of the aquarium.  Have the agent first destroy down, then place down and move forward by 1.  It will need to do these steps 3 times, except on the last run, do not have him move forward again. \n\n#### ~ tutorialhint\n```javascript\nplayer.onChat(\"base\",  function  ()  {\n\tif  (agent.getItemDetail(1)  ==  GLASS)  {\n\t\tagent.destroy(DOWN)\n\t\tagent.place(DOWN)\n\t\tagent.move(FORWARD,  1)\n\t\tagent.destroy(DOWN)\n\t\tagent.place(DOWN)\n\t\tagent.move(FORWARD,  1)\n\t\tagent.destroy(DOWN)\n\t\tagent.place(DOWN)\n\t}  else  {\n\n\t}\n})\n```\n\n## Step 5\n\nThe steps you created will build one row of 3.  You need to have the agent build the other 2 rows as well. \nFirst, have the agent turn left, move forward by 1, and then turn left again.  Then repeat the code you created for row 1.  \nFor row 3, have the agent turn right, move forward by 1, and then turn right again.  Then repeat the row 1 code again.  \n\n#### ~ tutorialhint\n```javascript\nplayer.onChat(\"base\",  function  ()  {\n\tif  (agent.getItemDetail(1)  ==  GLASS)  {\n\t\tagent.destroy(DOWN)\n\t\tagent.place(DOWN)\n\t\tagent.move(FORWARD,  1)\n\t\tagent.destroy(DOWN)\n\t\tagent.place(DOWN)\n\t\tagent.move(FORWARD,  1)\n\t\tagent.destroy(DOWN)\n\t\tagent.place(DOWN)\n\t\tagent.turn(LEFT_TURN)\n\t\tagent.move(FORWARD,  1)\n\t\tagent.turn(LEFT_TURN)\n\t\tagent.destroy(DOWN)\n\t\tagent.place(DOWN)\n\t\tagent.move(FORWARD,  1)\n\t\tagent.destroy(DOWN)\n\t\tagent.place(DOWN)\n\t\tagent.move(FORWARD,  1)\n\t\tagent.destroy(DOWN)\n\t\tagent.place(DOWN)\n\t\tagent.turn(RIGHT_TURN)\n\t\tagent.move(FORWARD,  1)\n\t\tagent.turn(RIGHT_TURN)\n\t\tagent.destroy(DOWN)\n\t\tagent.place(DOWN)\n\t\tagent.move(FORWARD,  1)\n\t\tagent.destroy(DOWN)\n\t\tagent.place(DOWN)\n\t\tagent.move(FORWARD,  1)\n\t\tagent.destroy(DOWN)\n\t\tagent.place(DOWN)\n\t}  else  {\n\n\t}\n})\n```\n\n## Step 6\n\nNow we need to add the else section of the if statement.  If the agent does not have glass blocks in it's inventory, set 64 glass blocks in slot 1.  \n\nThe code for that looks like this:\n\n`agent.setItem(GLASS,  64,  1)`\n\nAfter the agent has the inventory, it will need run the same base code as in the if section. \n\n\n#### ~ tutorialhint\n```javascript\nplayer.onChat(\"base\",  function  ()  {\n\tif  (agent.getItemDetail(1)  ==  GLASS)  {\n\t\tagent.destroy(DOWN)\n\t\tagent.place(DOWN)\n\t\tagent.move(FORWARD,  1)\n\t\tagent.destroy(DOWN)\n\t\tagent.place(DOWN)\n\t\tagent.move(FORWARD,  1)\n\t\tagent.destroy(DOWN)\n\t\tagent.place(DOWN)\n\t\tagent.turn(LEFT_TURN)\n\t\tagent.move(FORWARD,  1)\n\t\tagent.turn(LEFT_TURN)\n\t\tagent.destroy(DOWN)\n\t\tagent.place(DOWN)\n\t\tagent.move(FORWARD,  1)\n\t\tagent.destroy(DOWN)\n\t\tagent.place(DOWN)\n\t\tagent.move(FORWARD,  1)\n\t\tagent.destroy(DOWN)\n\t\tagent.place(DOWN)\n\t\tagent.turn(RIGHT_TURN)\n\t\tagent.move(FORWARD,  1)\n\t\tagent.turn(RIGHT_TURN)\n\t\tagent.destroy(DOWN)\n\t\tagent.place(DOWN)\n\t\tagent.move(FORWARD,  1)\n\t\tagent.destroy(DOWN)\n\t\tagent.place(DOWN)\n\t\tagent.move(FORWARD,  1)\n\t\tagent.destroy(DOWN)\n\t\tagent.place(DOWN)\n\t}  else  {\n\t\tagent.setItem(GLASS,  64,  1)\n\t\t\t\tagent.destroy(DOWN)\n\t\tagent.place(DOWN)\n\t\tagent.move(FORWARD,  1)\n\t\tagent.destroy(DOWN)\n\t\tagent.place(DOWN)\n\t\tagent.move(FORWARD,  1)\n\t\tagent.destroy(DOWN)\n\t\tagent.place(DOWN)\n\t\tagent.turn(LEFT_TURN)\n\t\tagent.move(FORWARD,  1)\n\t\tagent.turn(LEFT_TURN)\n\t\tagent.destroy(DOWN)\n\t\tagent.place(DOWN)\n\t\tagent.move(FORWARD,  1)\n\t\tagent.destroy(DOWN)\n\t\tagent.place(DOWN)\n\t\tagent.move(FORWARD,  1)\n\t\tagent.destroy(DOWN)\n\t\tagent.place(DOWN)\n\t\tagent.turn(RIGHT_TURN)\n\t\tagent.move(FORWARD,  1)\n\t\tagent.turn(RIGHT_TURN)\n\t\tagent.destroy(DOWN)\n\t\tagent.place(DOWN)\n\t\tagent.move(FORWARD,  1)\n\t\tagent.destroy(DOWN)\n\t\tagent.place(DOWN)\n\t\tagent.move(FORWARD,  1)\n\t\tagent.destroy(DOWN)\n\t\tagent.place(DOWN)\n\t}\n})\n```\n\n\n## Step 7\n\nRun the code by following the instructions in the next step.\n\n## Step 8 @unplugged\n\nTo test your code:\nOnce you have fully read this step click the Green Ok button below to close this window to return to the tutorial to perform the below steps to test your code.\n\n1.

Think of it like following a recipe step by step. Each instruction is completed before moving on to the next one.\n\n**In sequential computing, a computer executes instructions in a specific order, one after the other.** It starts with the first instruction, then moves to the second, and so on. It's similar to reading a book from the first page to the last page, without skipping or jumping ahead.\n\nA sequential solution takes as long as the sum of all of its steps.\n\n## Step 2 @unplugged\n\n**Parallel computing** is a method of processing information using multiple processors or computers simultaneously to solve complex problems or handle large amounts of data more quickly.\n\nThink of it like teamwork. Instead of one person doing all the work, **parallel computing allows multiple processors or computers to work together, dividing the task into smaller parts and solving them simultaneously.**\n\nEach processor or computer in parallel computing can handle a portion of the problem independently. They work together on different pieces of the task at the same time, like a team working on different parts of a project simultaneously.\n\nParallel computing can help speed up the processing time because multiple processors or computers are working in parallel, tackling different parts of the problem simultaneously. It can be especially useful for tasks that involve complex calculations or analyzing large sets of data. \n\nHowever, it's important to note that **not all problems can be easily parallelized.** Some tasks may have dependencies or require coordination between different parts, which makes parallel computing more challenging. Additionally, the effectiveness of parallel computing depends on factors such as the number of processors or computers available, the nature of the problem, and the efficiency of the parallel algorithms used.\n\n## Step 3 @unplugged\nIn parallel computing, the time it takes to complete a task depends on two things: the time it takes for sequential tasks and the time it takes for the longest parallel task.\n\nTo measure the effectiveness of a parallel solution, we use something called \"speedup.\" **Speedup tells us how much faster a parallel solution is compared to doing the same task sequentially.**\n\nTo calculate speedup, **we divide the time it took to complete the task sequentially by the time it took to complete the task in parallel.** The result gives us an idea of how much time we saved by using parallel computing.\n\nIn simpler terms, speedup measures how much faster we can finish a task by working together in parallel instead of doing it all by ourselves one step at a time.\n\n## Step 4 @unplugged\n\n**Distributed computing** is a method of processing information that involves multiple computers or devices working together as a team. It allows for collaboration and sharing of resources to solve complex problems or handle large amounts of data.\n\nThink of it like a group project. In distributed computing, each computer or device is like a team member with its own set of skills and capabilities. They communicate and work together to complete a task.\n\nInstead of having a single powerful computer doing all the work, **distributed computing divides the task into smaller parts and assigns them to different computers or devices.** Each computer or device works on its assigned part independently and shares the results with the other members of the team.\n\n## Step 5 @unplugged\n\nDistributed computing allows for **efficient use of resources** because each computer can contribute its processing power, memory, and storage to the overall task. This approach can **handle large amounts of data** and perform complex calculations faster than a single computer.\n\nMoreover, distributed computing is often used for **tasks that require a high level of reliability and fault-tolerance.** If one computer in the network fails or experiences a problem, the other computers can continue the work and maintain the overall functionality of the system.\n\nDistributed computing helps us solve problems that would be too big or take too long to handle on a single computer. It allows us to work with larger problems and solve them faster than we could with just one computer. By working together, we can solve bigger problems faster than if we tried to do it all on one computer.\n\n## Step 6 @unplugged\n\nNow that you know a little about these different types of computing, go to the next NPC to help the QA team with Advanced Logic.

We can use a 'for' loop with a 'let' function to run a block of code repeatedly. \n\nIn JavaScript, in order to run a 'for' loop, there are three things that need to be defined. Let's called them \"conditions\".\n1: Condition 1 will set a variable before the loop begins\n\t\tex. let i=0\n2: Condition 2 defines the condition for the loop to be run\n\t\tex. i<5\n3. Condition 3 is increases a value (i++) each time the code block in the loop has been executed.\n\nThis results in the the final code looking like this:\n\n```javascript\n    for (let i = 0; i < 5; i++)\n\n```\n\n## Step 2\n\nNow create a loop using the player.say command to count up to the number 10 in the chat.

However, these innovations can sometimes lead to unexpected outcomes. It is important to remember that people are the ones behind these computing advancements. As new technologies emerge, the way we perform tasks often evolves to incorporate them.\n\nHowever, not all the consequences of these innovations can be predicted beforehand. In fact, a single effect can be seen as both positive and negative, depending on the perspective of different individuals, or even the same person.\n\nThe progress in computing has not only impacted the field itself but has also sparked creativity in other areas such as medicine, engineering, communications, and the arts.

Take the World Wide Web, for example. It was initially created for scientists to easily share information, but now it's used by everyone for various purposes. Another example is targeted advertising, which was designed to help businesses reach potential customers, but it can also be misused and invade individuals' privacy.\n\nMachine learning and data mining have revolutionized fields like medicine, business, and science, enabling important discoveries.

The `for...in` loop in JavaScript is used to iterate over the properties of an object. It allows you to loop through the keys or property names of an object, giving you access to each key in each iteration. Here's how it works:\n\n```javascript\n    for (variable in object) { // code to be executed }\n```\nLet's break down the parts of the `for...in` loop:\n\n-   `variable`: A variable that represents the key or property name in each iteration.\n-   `object`: The object whose properties you want to iterate over.\n\n```javascript\n    const person = { \n    name: \"John\", \n    age: 25, \n    occupation: \"Engineer\" \n    }; \n\nfor (let key in person) { \nconsole.log(key + \": \" + person[key]); \n}\n```\nIn this example, we have an object `person` with properties like `name`, `age`, and `occupation`. The `for...in` loop allows us to iterate over the properties of `person` and access their values. In each iteration, the `key` variable represents the property name.\n`\n\n\n## Step 2\n\nTest the code to see how the code will output using the player.say command.\n\n  ```template\n  \n\n    const person = { name: \"John\", age: 25, occupation: \"Engineer\" }; for (let key in person) { console.log(key + \": \" + person[key]); }\n\n```\n\n  \n\n## Step 3\n\n\nNote that the order in which the properties are iterated is not guaranteed in JavaScript. If the order of iteration is important, consider using an array or a Map instead.\n\nIt's important to keep in mind that the `for...in` loop is specifically designed for objects. If you want to iterate over the elements of an array or a collection, the `for...in` loop is not recommended. Instead, you should use the `for` loop or other iteration methods like `forEach` or `for...of` loop.\n\n\n\n  \n\n## Step 4\n\nReturn to the game and move to the next NPC.","Lesson6/6.1/6.01.md":"# Expert Coding using JavaScript - Lesson 6 Activity 6.01\n### @explicitHints true\n\n\n\n## Step 1 @unplugged\n\nWhen you create something on a computer, like a document, image, or video, it becomes your intellectual property or belongs to the organization you work for.

It's important to take steps to protect intellectual property.\n\n\n## Step 2 @unplugged\nUsing someone else's material without permission and presenting it as your own is called plagiarism, and it can have legal consequences. However, there are legal ways to use materials created by others. For example, Creative Commons is a public copyright license that allows creators to share their work and let others use and build upon it. Open-source programs are freely available and can be redistributed and modified. Open access refers to research output that is freely accessible and has fewer restrictions on use, such as copyright or license restrictions.

The existence of computing devices that continuously monitor and analyze our activities raises privacy and ethical concerns.\n\n## Step 5 @unplugged\nIn conclusion, it's important to respect intellectual property rights, be aware of legal and ethical considerations when using computing technology, and understand the implications of innovations that raise concerns about privacy, bias, and access to digital information.","Lesson7/7.1/7.01.md":"# Expert Coding using JavaScript - Lesson 7 Activity 7.01\n### @explicitHints true\n\n## Step 1 @unplugged\n\nThe purpose of computing innovations is to solve problems or to pursue interests through creative expression.\nComputing innovations, which include software, hardware, and various technologies, are created with the intention of addressing real-world problems or fulfilling particular interests. For instance, applications like communication tools, social media platforms, productivity software, and video games are all examples of computing innovations designed to solve problems or cater to interests. Creative expression also plays a role, as developers often have the freedom to explore and create new technologies that can inspire, entertain, and inform.\n\n## Step 2 @unplugged\nAn understanding of the purpose of a computing innovation provides developers with an improved ability to develop that computing innovation.\nWhen developers have a clear understanding of the problem they're trying to solve or the goal they're pursuing, they can make informed decisions about design, features, and functionality. This understanding enables them to create innovations that align more closely with the intended purpose, leading to more successful and user-friendly solutions.\n\n## Step 3 @ unplugged\n\nYou will continue to learn about program function and purpose in each lesson as well as learning important programming information. \nGo to the next NPC to begin learning about Functions. ","Lesson7/7.1/7.1.md":"# Expert Coding using JavaScript - Lesson 7 Activity 7.1\n### @explicitHints true\n\n## Step 1 @unplugged\n\nAs code becomes more complex, programmers will need to break it down into smaller and more manageable pieces. So, programmers create **procedures,** also known as **functions or methods**, to generalize processes that can be reused. \n\nHere are some reasons we use functions. \n\n1.  **Reusability:** Functions allow you to define a block of code that can be **executed multiple times throughout your program**. Instead of writing the same code repeatedly, you can encapsulate it within a function and call that function whenever you need to perform a specific task.\n    \n2.  **Modularity:** Functions promote modular programming by **breaking down complex tasks into smaller, more manageable parts.** By dividing your code into functions, you can focus on solving individual problems and then combine these functions to create more significant functionality.\n    \n3.  **Abstraction:** Functions provide a way to abstract away the implementation details of a particular operation. This means that **you can use a function without knowing or understanding how it works internally**. By encapsulating complex logic within a function, you can simplify the code and make it easier to work with.\n    \n4.  **Code Organization:** Functions help in organizing and structuring your code. By grouping related pieces of code into functions, **you can improve code readability, maintainability, and reusability.** Functions allow you to separate different concerns and make your codebase more modular and easier to understand.\n \n\n## Step 2 \n\nTo define a function in Javascript, **you start with the word function followed by a name and then parentheses.**  Then the code to be executed, by the function, is placed inside curly brackets: **{}**\n\nEx: function name () {}\n\nWhen you name functions, follow the same rule as variables.  \nFunction names can only contain:\n\n - letters\n - digits\n - underscores\n - dollar signs\n\nLet's practice using functions by first defining a function named buildWall in the space below. \n\n#### ~ tutorialhint\n\n```javascript\nfunction buildWall ()  {\n\n}\n\n```\n\n\n## Step 3\n\nNext, inside the function, let's have the agent build a 4x4 wall by first having the agent place on move.  Then, add a loop that runs 2 times. Inside the loop, have the agent move forward by 3, up by 1, back by 3, and up by 1. \n\n#### ~ tutorialhint\n\n```javascript\n\nfunction buildWall ()  {\n\tagent.setAssist(PLACE_ON_MOVE,  true)\n\tfor  (let index =  0; index <  2; index++)  {\n\t\tagent.move(FORWARD,  3)\n\t\tagent.move(UP,  1)\n\t\tagent.move(BACK,  3)\n\t\tagent.move(UP,  1)\n\t}\n}\n\n```\n\n## Step 4\n\nNow we have defined the function by creating the reusable block of code.  To run that code, we need to **call** or **invoke** the function.  When you invoke a function, you're telling the computer to execute the instructions inside that function. When we make a function call, **it temporarily pauses the regular order of executing statements in a program**. Instead, it jumps to the statements within the function and runs them first. After the last statement in the procedure, or if there is a return statement, the program goes back to the exact point where the function was called and continues executing from there.\n\nTo call a function in JavaScript, you simply **write the function name followed by parentheses.** \n\nLet's create an on chat command named wall and call the function buildWall in the chat command. \n\n#### ~ tutorialhint\n\n```javascript\n\nplayer.onChat(\"wall\",  function  ()  {\n\tbuildWall()\n})\n\n```\n\n## Step 5\n\nRun the code by following the instructions in the next step.\n\n\n## Step 6 @unplugged\nTo test your code:\nOnce you have fully read this step click the Green Ok button below to close this window to return to the tutorial to perform the below steps to test your code.\n\n1.

We can do this by using something called \"**parameters\" or \"arguments\"**.\n\n**Parameters are like input variables that we can give to a function.** They allow us to pass data into the function, and the function can use that data to do its job. It's like giving instructions to the function on what data to work with.\n\n**Arguments are the actual values we provide for the parameters when we call or use the function.** We use arguments to specify the specific data that we want the function to process.\n\nIn addition to accepting inputs, functions can also give us outputs or results. We can get these results by using something called a \"return value\". When a function finishes running, it can send back a value to us. This can be something like a calculated value or any other result that we need.\n\nSo, by using parameters and arguments, we can make functions work with different data, and by using return values, we can get useful results from the function's execution. It's like giving instructions and receiving answers from a function.\n\n## Step 2 @unplugged\n\nIn JavaScript, the parameter name or names go in the parentheses after the function name like in the example below. \n\n    function name (parameter)  {\n    \n    }\n\nIn Microsoft MakeCode, we can use something called **\"type annotations\"** when adding parameters to functions in JavaScript. \n\nType annotations help the MakeCode editor understand the type of data that should be used for a parameter. They provide important information to the editor, which can then give us better suggestions while writing code and help us catch mistakes related to data types.\n\nTherefore, in Microsoft MakeCode after the parameter name you need to add a colon and then the data type as in the example below. \n\n    function name (parameter: dataType)  {\n    \n    }\n\nThe parameters can be the following data types. \n\n - Number\n - String\n - Boolean\n - Array\n - Object\n - Function\n - Undefined\n - Null\n - Symbol\n\n\n\n## Step 3 \n\nLet's practice declaring functions with parameters to see how they work. Once again we are going to define a function with the name buildwall. Do so in the space below. \n\n#### ~ tutorialhint\n\n```javascript\nfunction buildWall ()  {\n\n}\n\n```\n\n\n## Step 4\n\nWe are going to add the parameter of length. This will allow us to set the length to any number we want when we call the function. The data type of length should be number. \n\n#### ~ tutorialhint\n\n```javascript\nfunction buildWall (length: number)  {\n\n}\n\n```\n\n\n## Step 5\n\nNext, inside the function, let's have the agent build a wall where the parameter will have decided the height. First have the agent place on move.  Then, add a loop that runs length times. Inside the loop, have the agent move forward by 3, up by 1, back by 3, and up by 1. \n\n#### ~ tutorialhint\n\n```javascript\nfunction buildWall (length:  number)  {\n\tagent.setAssist(PLACE_ON_MOVE,  true)\n\tfor  (let index =  0; index < length; index++)  {\n\t\tagent.move(FORWARD,  3)\n\t\tagent.move(UP,  1)\n\t\tagent.move(BACK,  3)\n\t\tagent.move(UP,  1)\n\t}\n\t}\n\n```\n\n## Step 6\n\nWhen you call a function that has a parameter, you need to add the **argument** you want the parameter to be in parentheses. \nThese arguments are the **values that the function will work with to perform its task.**\n\nFor example:\n\t\n\t\n    functionName(value)\n\nNow, create an on chat command named wall that calls the function with the argument value of 2. \n\n#### ~ tutorialhint\n\n```javascript\nplayer.onChat(\"wall\",  function  ()  {\n\tbuildWall(2)\n})\n\n```\n\n## Step 7\n\nRun the code by following the instructions in the next step.\n\n\n## Step 8 @unplugged\nTo test your code:\nOnce you have fully read this step click the Green Ok button below to close this window to return to the tutorial to perform the below steps to test your code.\n\n1.

Instead of writing every single line of code for a specific task, you can use a library that already has that code written. \n    \n3.  **Specific Functions**: Libraries often focus on doing specific things really well. For example, you might use a library that's excellent at creating animations, or another one that's great at managing dates and time. These libraries give you special tools for different parts of your project.\n    \n4.  **Sharing with Others**: Programmers share their libraries with others. It's like a big community where people help each other by offering their pre-made code for everyone to use.\n    \n5.  **Working Together**: Libraries also help different parts of your program work together smoothly. When you're building something complex, like a website, you can use libraries to handle different tasks, like making things look nice or handling user interactions.\n\n## Step 2\n\nApplication program interfaces (APIs) are specifications for how the procedures in a library behave and can be used.\nDocumentation for an API/library is necessary in understanding the behaviors provided by the API/library and how to use them.\nLet's break down these concepts. \n\n1.  **Application Programming Interfaces (APIs)**: APIs are like rules and instructions that help different software components communicate and work together. It specifies what functions (procedures) are available, what kind of information they need, and what they will give back. Developers follow the API to use the library's functions in their programs.\n       \n2.  **Documentation Importance**: When you're using a library or an API, you need documentation to understand what each function does, what data it expects, and what it returns. It's like your manual to making the most of the library.\nWithout API documentation, developers would struggle to use a library effectively because they wouldn't know how its functions behave and fit together.  API documentation guides developers on how to call functions correctly, what arguments to provide, and what results to expect. This ensures they're using the library in the right way.\n\n## Step 3\n\nMakeCode itself provides a range of built-in libraries and extensions however  you will not be able to directly use external libraries that are typically used in languages like Python or JavaScript. Instead, you would usually rely on the libraries and extensions provided within the MakeCode environment.\n\n## Step 4\n\nGo to the next activity to practice using one of the built-in libraries in MakeCode.

This ability to accommodate diverse inputs and situations is crucial to ensure that the program remains reliable and useful to a wide range of users. It involves thorough testing, error handling, and consideration of various use cases during the development process.\n\n## Step 2 @unplugged\n\n**The behavior of a program is how a program functions during execution and is often described by how a user interacts with it.**\nIt includes all the actions and responses that the program produces in response to user input or other triggers. The way the program responds to your actions and the outcomes it produces collectively define its behavior.\nMoreover, **a program can be described broadly by what it does, or in more detail by both what the program does and how the program statements accomplish this function.**\n\n## Step 3 @unplugged\n\nProgram inputs are data sent to a computer for processing by a program. Input can come in a variety of forms, such as tactile, audio, visual, or text.\n\n-   **Tactile:** Physical actions like pressing keys on a keyboard, clicking a mouse button, or tapping on a touch screen.\n-   **Audio:** Spoken commands, voice recognition, or sound signals.\n-   **Visual:** Images, videos, graphics, or visual cues from a camera.\n-   **Text:** Typing text, entering commands, or providing textual information.\n\nProgram inputs vary based on the nature of the program and the ways users interact with it. \nInputs usually affect the output produced by a program.\n\n## Step 4 @unplugged\n\n**Input can come from various sources.** Users can provide input by interacting with a program using devices like keyboards, mice, touch screens, and microphones. \nAdditionally, input can come from other programs.

JavaScript provides several built-in collection types, such as arrays, sets, and maps. Let's explore each of them in detail:\n\n\n1.  **Arrays:** Arrays are the most commonly used collection type in JavaScript. They are ordered, indexed collections of values, where each value is associated with a numeric index. Arrays can store values of different types, including numbers, strings, objects, and even other arrays. Here's an example of an array:\n\n\n```javascript\n    const fruits = [\"apple\", \"banana\", \"orange\"];\n```\n\n\nArrays have a variety of built-in methods that you can use to manipulate and access their elements, such as `push()`, `pop()`, `slice()`, `forEach()`, and more.\n\n\n## Step 2 @unplugged\n\n2.  **Sets:** Sets are collection types that store unique values, meaning that each value can occur only once within the set. Unlike arrays, sets are unordered, and the order of elements is not guaranteed. Here's an example of a set:\n\n\n```javascript\n    const colors = new Set([\"red\", \"green\", \"blue\"]);\n```\n\nSets have methods for adding, deleting, and checking the presence of elements, such as `add()`, `delete()`, and `has()`.\n\n\n  \n\n## Step 3 @unplugged\n\n\n3.  **Maps:** Maps are collections that store key-value pairs, where each value is associated with a unique key. Maps allow you to store and retrieve values based on their keys, providing a more flexible alternative to arrays. Here's an example of a map:\n\n\n\n```javascript\n    const user = new Map();\nuser.set(\"name\", \"John\");\nuser.set(\"age\", 25);\n```\n\nMaps have methods for adding, deleting, and retrieving values based on keys, such as `set()`, `delete()`, and `get()`.\n\n  \n\n## Step 4 @unplugged\n\n4.  **WeakSet and WeakMap:** WeakSet and WeakMap are special collection types in JavaScript that have limited use cases. They are similar to sets and maps, respectively, but with some important differences. WeakSets and WeakMaps allow you to store only objects as keys, and they do not prevent the objects from being garbage collected by JavaScript's memory management system.\n\nThese are the basic collection types in JavaScript. Each collection type has its own characteristics and methods for manipulation and retrieval of data. Choosing the right collection type depends on your specific use case and requirements.\n\nIt's important to note that in addition to these built-in collections, JavaScript also provides various methods and functionalities for working with collections, such as iterating over elements using loops (`for...of`), using array methods like `filter()`, `map()`, and more.\n\nUnderstanding collections is fundamental for organizing and managing data in JavaScript, and they are widely used in many programming tasks.\n\n\n  \n\n\n\n\n","Lesson9/9.1/9.01.md":"# Expert Coding using JavaScript - Lesson 9 Activity 9.01\n### @explicitHints true\n\n## Step 1 @unplugged\n\nLet's continue learning about program function. \n**A program is a collection of program statements that performs a specific task when run by a computer.** \nA program is essentially a set of instructions written in a programming language that tells a computer what tasks to perform.

We use mathematical expressions called polynomials to describe this growth.\n\n## Step 2 @unplugged\n\nAlgorithms with **exponential or factorial efficiencies** are examples of algorithms that run in an **unreasonable amount of time.**\n\n   Some problems cannot be solved in a reasonable amount of time because there is no efficient algorithm for solving them. In these cases, approximate solutions are sought. \n   \n   A **heuristic** is an approach to a problem that produces a solution that is **not guaranteed to be optimal but may be used when techniques that are guaranteed to always find an optimal solution are impractical.**\n   ","Lesson9/9.2/9.2.1.md":"# Expert Coding using JavaScript - Lesson 9 Activity 9.2.1\n### @explicitHints true\n\n\n## Step 1\n\nIn the last activity, you built a code that used a conditional statement.

It explains what the software is designed to do and its role within the larger system.\n    \n2.  **Code Explanation:** Documentation offers a detailed explanation of the code's logic, structure, and algorithms. It breaks down complex sections of code into manageable parts, making it easier for developers to understand and work with the codebase.\n    \n3.  **Usage Instructions:** Documentation provides instructions on how to use the code or software. This includes information on input formats, parameters, expected outputs, and any relevant usage examples. Proper usage instructions help other developers integrate the code correctly into their projects.\n    \n4.  **Dependencies and Requirements:** Documentation lists any external libraries, frameworks, or resources that the code relies on. It also outlines the hardware or software requirements for running the code successfully. \n\n5. **Contributor Guidelines:**\nIt is important to acknowledge any code segments that were developed collaboratively or by another source.

For example, when you click a button on a webpage, that's an event. The action of clicking triggers an event, and the program responds accordingly. The data associated with the event might include information about where you clicked or what button was pressed.\nEvents can be generated when a key is pressed, a mouse is clicked, a program is started, or any other defined action occurs that affects the flow of execution.\n\n## Step 2 @unplugged\n\n**In event-driven programming, program statements are executed when triggered rather than through the sequential flow of control.**\nIn event-driven programming, the flow of control doesn't follow a strict linear sequence from one line of code to the next.

Programming languages define their own run-time errors.\n\nAn **overflow error** is an error that occurs when a computer attempts to handle a number that is outside of the defined range of values.\nLet's look into each of these error types individually. \n\n## Step 2 @unplugged\n\nLogic errors in JavaScript, also known as \"bugs,\" occur when the code does not behave as intended due to flaws in the program's logic. Unlike syntax errors, which result from incorrect language usage, logic errors lead to unexpected outcomes that may not trigger any error messages. Here are a few examples of logic errors you may see in your code. \n\n**Incorrect Conditions or Expressions:** Logic errors often arise from mistakes in conditions or expressions used in conditional statements (if, else if, else) and loops (for, while). Incorrectly evaluating conditions can cause the code to take the wrong path or loop more or fewer times than intended.\n\n**Off-by-One Errors:** These errors occur when iterating through arrays or other data structures, and the loop runs one too many or too few times. This often happens due to using the wrong comparison operator or mismanaging array indices.\n\n**Misunderstanding Operator Precedence:** JavaScript operators have precedence rules that determine how expressions are evaluated. Mixing operators without considering their precedence can lead to incorrect results.\n\n## Step 3\n\nThe code below is supposed to make a 4x4 solid square on the grass when the player types run but it has a 3 logic errors.

By feeding your code with various inputs and comparing the outputs to the expected results, you can quickly identify if your code is behaving as intended. Test cases help catch errors early and provide a structured way to verify your code's functionality.\n   \n\n## Step 3 @unplugged\n\n**Hand Tracing:** Hand tracing involves mentally simulating the execution of your code step by step. You go through the code line by line, tracking the values of variables and the flow of control. This method helps you identify logic errors or unexpected behaviors in your code. It's like walking through the code manually to understand how it works.\n    \n\n## Step 4 @unplugged\n\n**Visualizations:** Visualizations can be helpful for understanding complex algorithms or data structures. Diagrams, flowcharts, or even drawing out the relationships between components can make it easier to spot errors in your logic. Visualizations provide a higher-level view of your code's structure and can reveal patterns that might not be apparent in the code alone.\n\n## Step 5 @unplugged\n\n**Debuggers:** Debuggers are tools built into integrated development environments (IDEs) that allow you to pause your code's execution at specific points and inspect the values of variables. You can set breakpoints, step through your code line by line, and observe the state of your program at each step. Debuggers are powerful tools for pinpointing errors and understanding the behavior of your code during runtime.\n\n## Step 6 @unplugged\n\n**Adding Extra Output Statements:** Adding extra output statements involves inserting console log statements in your code to print out the values of variables or specific messages at certain points. This can help you track the flow of your code and understand what's happening at different stages of execution. By observing the output in the console, you can identify where things might be going wrong.\n\n## Step 7 @unplugged\n\nUsing a combination of these methods can greatly enhance your ability to find and fix errors in your code.

The development team follows a predefined set of steps, tasks, and milestones.\n\n**Exploratory development** processes are more flexible and adaptive. The team starts with a general direction or concept but allows for experimentation, creativity, and adaptation as the project progresses.\n\nThe choice between an ordered and intentional approach or an exploratory approach should be made based on factors such as project complexity, available resources, timeline constraints, and the level of uncertainty involved.\n\n## Step 2 @unplugged\nA development process can be iterative or incremental. \n\nA development process that is iterative **requires refinement and revision based on feedback, testing, or reflection throughout the process.** This may require revisiting earlier phases of the process.\n\nA development process that is incremental is one that **breaks the problem into smaller pieces and makes sure each piece works before adding it to the whole**.\n\nAs you have seen, there are multiple development processes.  However, the following phases are commonly used when developing a program: \n\n - investigating and reflecting\n - designing\n - prototyping\n - testing\n\nLet's go through each of these steps individually. \n\n\n## Step 3 @unplugged\n\n**Investigating and Reflecting**\n\nThe investigating and reflecting step involves researching and gathering information to understand the problem or opportunity that the development process aims to address. \nIt's important to identify the requirements, constraints, and goals of the project.\n **Program requirements** describe how a program functions and may include a description of user interactions that a program must provide. \nInvestigation in a development process is also useful for understanding and identifying the **program constraints**, as well as the concerns and interests of the people who will use the program.\n\nSome ways investigation can be performed are as follows: \n\n - collecting data through surveys \n - user testing\n - interviews\n - direct observations\n\nThis phase helps in setting the foundation for the rest of the development process.\n\n## Step 4 @unplugged\n\n**Design Phase**\n\nIn a development process, the design phase **outlines how to accomplish a given program specification.** A program’s specification defines the requirements for the program.\n\nThe design phase of a program may include: \n\n - brainstorming\n - planning and storyboarding\n - organizing the program into modules and functional components\n - creation of diagrams that represent the layouts of the user interface\n - development of a testing strategy for the program\n\n## Step 5 @unplugged\n\n**Prototyping**\nPrototyping is a step that involves **creating a simplified, functional version of the product or solution.** This version, known as a prototype, allows stakeholders to see and interact with a tangible representation of the design. Prototypes can take various forms, from paper sketches to interactive digital models. The purpose of prototyping is to validate design decisions, test user interactions, and identify potential issues early in the development process. Feedback gathered from testing the prototype helps in refining the design before proceeding further.\n\n\n## Step 6 @unplugged\n\n**Testing**\nIn the development process, **testing uses defined inputs to ensure that an algorithm or program is producing the expected outcomes.** Programmers use the results from testing to revise their algorithms or programs.\nDefined inputs used to test a program should demonstrate the different expected outcomes that are at or just beyond the extremes. Program requirements are needed to identify appropriate defined inputs for testing.\n\nTherefore, testing should include a wide range of inputs, with a specific focus on inputs that challenge the program's boundaries. This helps identify and address potential issues, ensuring the program's robustness and reliability in real-world use.\n\n## Step 7 @unplugged\n\nNow that you understand more about the development process, go to the next NPC to begin working through the development process for your own program.

You will know your code is correct when the agent moves forward by 1 and  places a cornflower on the grass block. \n\n## Step 6\n\nWhen your code works as expected move on to the next activity.\nIf it does not work as expected, try to fix and test again.","pxt.json":"{\n    \"name\": \"coding-in-minecraft-expert-javascript\",\n    \"version\": \"0.0.15\",\n    \"description\": \"\",\n    \"dependencies\": {\n        \"core\": \"*\",\n        \"builder\": \"*\"\n    },\n    \"files\": [\n        \"Lesson1/1.1/1.1.9.md\",\n        \"Lesson1/1.2/1.2.2.md\",\n        \"Lesson1/1.1/1.1.8.md\",\n        \"Lesson1/1.1/1.1.7.md\",\n        \"Lesson1/1.1/1.1.6.md\",\n        \"Lesson1/1.1/1.1.5.md\",\n        \"Lesson1/1.1/1.1.4.md\",\n        \"Lesson1/1.1/1.1.md\",\n        \"Lesson1/1.1/1.1.2.md\",\n        \"Lesson1/1.1/1.1.3.md\",\n        \"Lesson1/1.2/1.2.md\",\n        \"README.md\",\n        \"main.blocks\",\n        \"main.ts\",\n        \"Lesson2/2.1/2.1.md\",\n        \"Lesson2/2.1/2.01.md\",\n        \"Lesson2/2.1/2.2.md\",\n        \"Lesson2/2.1/2.3.md\",\n        \"Lesson2/2.1/2.4.md\",\n        \"Lesson2/2.1/2.5.md\",\n        \"Lesson3/3.1/3.1.md\",\n        \"Lesson3/3.1/3.01.md\",\n        \"Lesson3/3.2/3.2.md\",\n        \"Lesson3/3.2/3.2.1.md\",\n        \"Lesson3/3.1/3.1.2.md\",\n        \"Lesson3/3.3/3.3.md\",\n        \"Lesson3/3.3/3.3.1.md\",\n        \"Lesson3/3.3/3.3.2.md\",\n        \"Lesson4/4.1/4.1.md\",\n        \"Lesson4/4.1/4.01.md\",\n        \"Lesson4/4.1/4.1.1.md\",\n        \"Lesson4/4.2/4.2.md\",\n        \"Lesson4/4.2/4.2.1.md\",\n        \"Lesson4/4.2/4.2.2.md\",\n        \"Lesson4/4.3/4.3.1.md\",\n        \"Lesson4/4.3/4.3.md\",\n        \"Lesson5/5.1/5.1.md\",\n        \"Lesson5/5.1/5.01.md\",\n        \"Lesson6/6.1/6.1.md\",\n        \"Lesson6/6.1/6.01.md\",\n        \"Lesson7/7.1/7.01.md\",\n        \"Lesson7/7.1/7.1.md\",\n        \"Lesson7/7.1/7.1.1.md\",\n        \"Lesson7/7.1/7.1.2.md\",\n        \"Lesson7/7.2/7.2.md\",\n        \"Lesson7/7.2/7.2.1.md\",\n        \"Lesson7/7.3/7.3.md\",\n        \"Lesson7/7.3/7.3.1.md\",\n        \"Lesson7/7.3/7.3.2.md\",\n        \"Lesson7/7.3/7.3.3.md\",\n        \"Lesson8/8.1/8.01.md\",\n        \"Lesson8/8.1/8.1.md\",\n        \"Lesson9/9.1/9.01.md\",\n        \"Lesson9/9.1/9.1.md\",\n        \"Lesson9/9.1/9.1.1.md\",\n        \"Lesson9/9.1/9.1.2.md\",\n        \"Lesson9/9.2/9.2.md\",\n        \"Lesson9/9.3/9.3.md\",\n        \"Lesson9/9.3/9.3.1.md\",\n        \"Lesson9/9.3/9.3.2.md\",\n        \"Lesson9/9.2/9.2.1.md\",\n        \"Lesson9/9.2/9.2.2.md\",\n        \"Lesson10/10.1/10.1.md\",\n        \"Lesson10/10.1/10.01.md\",\n        \"Lesson10/10.1/10.1.2.md\",\n        \"Lesson10/10.1/10.1.1.md\",\n        \"Lesson10/10.2/10.2.md\",\n        \"Lesson10/10.2/10.2.1.md\",\n        \"Lesson10/10.2/10.2.2.md\",\n        \"Lesson10/10.2/10.2.3.md\",\n        \"Lesson10/10.2/10.2.4.md\",\n        \"Lesson11/11.1/11.01.md\",\n        \"Lesson11/11.1/11.1.md\",\n        \"Lesson12/12.1/12.1.md\",\n        \"Lesson12/12.1/12.1.1.md\",\n        \"Lesson12/12.1/12.1.2.md\",\n        \"Lesson12/12.1/12.1.3.md\",\n        \"Lesson12/12.1/12.1.4.md\",\n        \"Lesson3/3.1/3.1.1.md\"\n    ],\n    \"testFiles\": [\n        \"test.ts\"\n    ],\n    \"public\": true,\n    \"targetVersions\": {\n        \"target\": \"1.7.13\",\n        \"targetId\": \"minecraft\"\n    },\n    \"supportedTargets\": [\n        \"minecraft\"\n    ],\n    \"preferredEditor\": \"tsprj\"\n}\n","test.ts":"// tests go here; this will not be compiled when this package is used as an extension.\n"}}],"shares":[]}
