Comments

100

How do you make a comment?

by putting // in the beginning

ex: 

//this is a comment

200

Why do we use comments?

So that we/other people looking at our code understands what it does

They store information so that you can use later on.

300

Which one is a variable?

a) //var v = 0;

b) var v = "hello";

c) if(time > 0){console.log('hello')}

b. because it starts with var. a would be a variable if it didnt have // in front but with // its not a comment.

400

Create your own variable and set it equal to whatever you want

3 parts to a variable.

1) var in the beginning

2) create a unique name

3) set it equal to something (optional)

Ex: var cookie = 1;

500

Create a variable called cookie and set it equal to 0.

var cookie = 0;

Loops

100

How do you make a loop that goes on forever?

you start with the word while.

200

what do while loops do?

basically they go on until the condition you put inside of it is false. basically looks like...

ex: the condition is age < 10. while loops go on until age is no longer < 10.

var age = 0;

while(age < 10){

age+=1;

}

console.log(age);

// should print out 10

300

Which one is a loop?

a) while(true){console.log("hi")}

b) if(true){console.log("hey")}

c) //loop

a is a loop.

400

Create your own while loop.

ex: while(true){

console.log("hi")

}

500

create a while loop that will make the hero move left then right indefinitely. 

while(true){

hero.moveLeft();

hero.moveRight();

}

Statements I

100

hero.moveRight();

200

hero.attack(enemy);

400

while(true){

hero.moveUp();

hero.moveLeft();

hero.moveDown();

hero.moveRight();

}

500

Create a variable called steps and set it equal to 1.

var steps = 1;

while(true){

hero.moveUp(steps)

}
