For Loop JavaScript

A for loop lets us repeat code a fixed number of times.

For example, if we want to move 10 spaces or put down 15 tennis balls, we would use a for loop. If we want to move to the wall, but don’t know how far away the wall is, we would not use a for loop.

A for loop looks like:

for(var i = 0; i < 10; i++){
   move();
}

This calls the move() command 10 times, and does the same thing as writing.

move();
move();
move();
move();
move();
move();
move();
move();
move();
move();
