Visual Event. External code loading bookmarklet that visualises the JavaScript events hooked up to the current page, and lets you view the source code of the event handling function for each one. Only works for events added by jQuery, YUI or MooTools since those libraries maintain a cache of event handlers that they add, to work around the standard DOM’s omission of handler introspection.

Doctype: /trunk/goog. Google’s newly released JavaScript library (pure JavaScript, so more along the lines of YUI and jQuery than GWT). I haven’t found the documentation for it yet, but the code is extremely well commented. UPDATE: The documentation is spread throughout Doctype.

Ext JS. Jack Slocum is building a business around his excellent Ext JavaScript library (which can now run on top of YUI, jQuery or Prototype). The library itself is LGPL, but you can pay for a commercial license and support.
