It's a very approachable language for the beginner that quickly scales to be as powerful a tool as your skills allow.

In the long-gone days of the early Internet, having a form on the website was tantamount to dabbling with "cutting-edge" technologies. Intricate Perl scripts and esoteric CGI scripts were required to process those forms and people used to suffer bouts of cold sweat whenever there manifested a need to use web forms.

A Simple Image/Link Rollover in Javascript
By Benjamin Glenn
Your web site has been up and running for some time and while you are pleased with the results, you can't help but think that it needs a little bit more "something". Maybe you want to do something with the links, like add some pictures or a "rollover effect". Well, maybe not all the links; just one or two. There's a fine line between classy and gaudy.

Higher Order Programming in JavaScript
By Sjoerd Visscher
Higher Order Programming is the ability to use functions as values. So you can pass functions as arguments to other functions and functions can be the return value of other functions.
