I'm confused, the code doesn't see to return integer or object or whatever, so what's the purpose of "return" in the snippet? thanks

I'm assuming this is in a jQuery environment?

If so, then the outer function will return the value returned by the .each() method, which, if you look at the jQuery docs, will be the same jQuery wrapped set that .each() is called upon.

In other words: the value of this on line 3.
