+
+//Question 1...What is a variable?
+//Answer 1...a variable stores data
+
+//Question 2...What is the difference between let and const?
+//Answer 2..."let" can be changed, "const" cannot be changed
+
+//Question 3...What does console.log() do?
+//Answer 3..it prints the data to the console
+
+//Part 2-CONDITIONALS

+//Question 1...Why are functions useful?
+//Answer 1..."functions" can reuse code
+
+//Question 2...What is a parameter?
+//Answer 2...a "parameter" = input to function
+
+//Question 3...What is the difference between console.log() and return?
+//Answer 3...a "return" gives back a value, a "console.log" just prints it out

+
+//Question 1...What is a loop used for?
+//Answer 1...to repeat code multiple times
+
+//Question 2...When might you use a for loop?
+//Answer 2..when you know you want to repeat something multiple times
+
+//Question 3...What could happen if a loop condition never becomes false?
+//Answer 3...the loop will just keep repeating

+
+//Reflection Questions
+
+//Which topic felt easiest for you?
+//I felt easier with the variables section
+
+//Which topic felt most challenging?
+//For me it was the loops and arrays...it was more so a refresher that was needed
+
+//How do variables, conditionals, functions, and loops work together in a program?
+//the variables hold the information 
+// the conditionals check to see is the variables meet the condition
+//loops repeats the blocks of code based off the conditions
+//functions encapsulate the structures allowing tasks to be reused
+
+//What is one question you still have about JavaScript?
+//I still want to see how everything ties together from my previous learnings
