Jack Slocum, author of YAHOO.Ext, has recently launched http://extjs.com/. Initially, I thought the site was a remake of his personal site http://jackslocum.com/ with a greater focus on his YUI extension library. However, upon closer inspection, the new website is dedicated to framework interoperability. And since this blog has a similar mission, I felt it worth mentioning. Anyway, Ext already works with YUI, jQuery, Prototype, and Scriptaculous.

Note

Ext now works as a standalone Framework, without any other library. Although, I am impressed with the work this team has put into Ext, it is to heavy for most websites. Using this Framework, it is easy to create JavaScript libraries in excess of 300k.
