Jack,
jQuery provides shortcuts but does not *require* them. NoConflict
with other libraries has been a priority from the beginning, and all
core code and proper plugins are written with this in mind. Please
read the API documentation for noConflict to see how you NEVER have to
use $ to use jQuery:
http://docs.jquery.com/Core/jQuery.noConflict
Note the example:
var j = jQuery.noConflict();
// Do something with jQuery
j("div p").hide();
// Do something with another library's $()
$("content").style.display = 'none';
Also, using $ inside closures (as John noted) saves space without ever
conflicting! This way jQuery has the best of both worlds: a clean
packaged namespace AND shortcuts which save space.
