+1. What is a variable?
+    -A variable is a container for storing data values. It allows you to store and manipulate information in your code.
+2. What is the difference between let and const?
+    -The main difference between let and const is that let allows you to change the value of the variable, while const does not allow changing. Once a value is assigned to a const variable, it cannot be changed.
+3. What does console.log() do?
+    -console.log() is a function that prints out the information that is passed into the console.

+//Practice 2: Write Condtionals 
+
+//Task A
+let temperature = 70;
+
+if (temperature > 60) {
+    console.log("It is cold");
+} else {
+    console.log("It is warm");

+if (password == "javascript123") {
+    console.log("Access granted");
+    }

+//Task C
+let hour = 3;

+Check for Understanding
+
+1. What is the purpose of an if statement?
+    -An if statement is used to execute a block of code only if a specified condition is true. It allows you to make decisions in your code based on certain conditions.
+2. When would you use else if?
+    -You would use else if when you have multiple conditions to check. It allows you to specify additional conditions to be evaluated if the previous conditions are false.
+3. What does === check for?
+    -The === operator checks for strict eqaulity, meaning it checks if two values are equal and of the same data type.
+*/
+
+//Practice 3: Build Functions
+
+//Task A
+function sayHello(){
+    console.log("Hello");
+}
+sayHello();
+
+//Task B
+function favoriteFood(food){
+    console.log("My favorite food is " + food);
+}
+favoriteFood("wings");
+
+//Task C
+function multiply(a,b){
+    return a * b;
+}
+
+let result = multiply(5, 10);
+console.log("The result is: " + result);
+
+//Task D
+function isEven(number){
+    if (number % 2 === 0);
+}
+
+console.log(isEven(2)); // true
+console.log(isEven(3)); // false

+Check for Understanding
+1. Whay are functions useful?
+    - Functions are useful because they allow us to reuse code and organize it into logical blocks.
+2. What is a parameter?
+    - A parameter is a value that a function recevies. It is used to pass information into a function. 
+3. What is the difference between console.log() and return?
+    - console.log() prints a value to the console. Return prints a value from the function that was called.
+*/
+
+// Practice 4: Use Loops
+
+//Task A
+for(let i = 1; i <= 10; i++){
+    console.log(i);
+}
+
+//Task B
+for(let i = 2; i <= 20; i += 2){
+    console.log(i);
+}
+
+//Task C
+let h = 5;
+
+while(b >= 1){
+    console.log(b);
+    b --;
+}
+
+//Task D
+for(let r = 0; r < 5; r++){
+    console.log("Practice makes progress")
+}
+
+/*
+Check for Understanding
+1. What is a loop?
+    - A loop is used to repeat a block of code multiple times until a certain condition is met.
+2. When might you use a for loop
+    - A for loop is useful when you know how many time you want to repeat a block of code.
+3. What could happen if a loop condition never becomes false?
+    - If a loop condition never becomes false, then the loop is a inifinte loop and runs forever.

+
+//Reflection Questions
+
+/*
+1. Which topic felt easiest for you?
+    - The easiest topic for me was variables, it was easy for me to declare variables since it is so close to working with Java. 
+2. Which topic felt the most challenging?
+    - The most challenging topic was remembering the syntax and structure differences from Java.
+3. How do variables, conditionals, functions, and loops work together in a program?
+    - Variables store information, conditionals allow us to make decisions based on a statement that uses a variable,
+    functions allow us to organize code into resuable blocks, and loops allow us to repeat a code multiple times. 
+4. What is one question you still have about JavaScript?
+    - What is the major difference between using JavaScript and Java?
