To answer this question very well, look at the book by Sitepoint.com
called "Simply Javascript". They explain how Javascript Frameworks
(like jQuery) are used to simplify Javascript techniques. In this
book, they actually build their own Javascript framework. For
instance, being able to select an element by its class name in jQuery
with $(".element") actually tells Javascript, "If you're Internet
Explorer, grab the element by it's class this way, if your not, do it
another way." So, using jQuery, we don't have to worry about doing
this EVERY time we want to select an element by its class name. This
is just one example. Check out the book.
