Hoisting is great thing, it is really helpful to improve readability when doing asynchronous function calls.

    function a(){
      setTimeout(b, 1000);
    }

    function b() {
      setTimeout(c, 1000);
    }

    function c() {
    }

If I'm not mistaken that's not hoisting, since that code will work as long as a() is called after b is declared regardless of the hoisting. Keep in mind b is only accessed when a() is actually executed, not when it's declared!

Hoisting works like this:

    a();

    function a() {
      console.log("FOO");
    }

Which might or might not be more readable, depending on your tastes.

You're right, my example was not very good indeed.
