Awesome Frameworks/Libraries

Prototype JavaScript frameworkPrototype JavaScript framework

Prototype was one of the first popular frameworks. Several libraries and frameworks are based on Prototype (or still require it).


jQuery is lightweight, elegant, and touted as one of the easiest JS frameworks to use.


My personal favorite.

The Yahoo! User Interface Library (YUI)The Yahoo! User Interface Library (YUI)

A big and extremely robust JavaScript toolkit by Yahoo!.


JavaScriptMVC is a relatively new but very promising framework that offers a lot of unique components and features not found in other frameworks.

A robust effects library that’s been used by top websites such as Digg, Feedburner, and Apple; requires the inclusion of Prototype.

Ext JSExt JS

Another solid framework; it does have a restrictive license for commercial purposes. Check out the Web Desktop demo.


MochiKit is a robust library that offers a lot of utility functions and effects classes.


Dojo is another framework to consider. visit the Spotlight section on the website to see real companies using Dojo.
