Function JavaScript

A function is a way to teach Karel a new word. Functions should do one thing, and should be written like a command. They are named in lowerCamelCase.

For example, we could teach karel to move to the wall with a function like

function moveToWall(){
    while(frontIsClear()){
        move();
    }
}

We use functions when we want to look for patterns in the code.
