There and Back Again

Dojo is a class library for JavaScript and DHTML. At the core of Dojo is a package system that can include as little or as much of this class library as your application needs. Dojo "plays nice" with other tools (does not pollute gloabal objects or namespace) and is lightweight to develop with and even faster when you deploy it. Dojo provides a capable widget system that makes building and using widgets in markup drop-dead easy. Overviews of many parts of the system are available on the Dojo wiki at http://dojo.jot.com.
