$ is an alias to a function named "jQuery", which returns a jQuery object.
If you're familiar with Object Oriented Programming, you can think of $(...)
and jQuery(...) as sort of like constructor functions. Actually, now that I
think about it
var $foo = jQuery("#foo");
is just a shortcut for
var $foo = new jQuery("#foo");
From the jQuery source:
var jQuery = function(a,c) {
// If the context is global, return a new object
if ( window == this )
return new jQuery(a,c);
// rest of "jQuery" function.....
Typical usage of jQuery(...) will trigger the code on line 4
