- IE8 Beta 2 currently available

IE8 developer toolbar
- multiple document modes - can test different versions of IE within IE8
- idea is to be able to debug everything within IE, don’t have to go to any other program
- basically copied firebug on everything: look, layout, features (* Bri’s opinion: no complaints, really)
- CSS cascade, DOM inspection, box model layout, etc.
- js console, live debugging
- js profiling, include time & execute time, how many times it was called

Visual Studio 2008
- javascript editor/debugger
- colorization, formatting, code completion, debugger
- works with popular js frameworks
- free download: Visual Web Developer Express 2008
- code completion works with dynamic typing, will show you the code completion for the current type
- code completion across libraries, user-defined objects & functions
- can annotate functions to tell it param and return types for code completion
- can annotate to explicitly bring in other js files to the code completion

jQuery Partnership
- fully documented jQuery included, with full code completion
- with jQuery, if reference minified version, will automatically bring in the debug version for development

* At this point I stopped paying attention as they went into their ASP.NET AJAX framework and related stuff.
