Return JavaScript

Exit a function and return a value.

One valuable aspect of functions is that they can perform some computations and return the result. The following code has a helper function that returns “hello world” when the function is called. The return value is stored into a variable, which is then printed:

function start() {
    var textToPrint = getHello();
    println(textToPrint);
}

function getHello() {
    var string = "hello world";
    return string;
}

Functions can return many different types of results, such as strings, integers, shapes, and more.
