So then it pulls part of a function?
Is 'this' in the example you made pulls $("div") or $("div").each
It doesn't pull part of a function...it pulls the object within which the
function is executing.
In my example, the function is "each", and the object within which it is
executing is the jQuery object (which is an array of div elements) returned
by $("div"). So, "this" would refer to the current div element which is
being iterated.
It's not easy to wrap your mind around it, it definitely takes some time and
experimentation to see how it works.

So, if you have a bunch of divs:
$("div").each(function() {
console.log(this);
});
You will see in the console each of the divs as it loops over them.
Every javascript function runs within the context of some object -- at
the
highest level this is the window (global) object.
To understand context and scoping better, I highly recommend checking out
John Resig's book "Advanced JavaScript Techniques," it cleared up a lot
of
confusion for me.
