I'm preparing another (hopefully) useful full length article, but in the mean time I want to share with you a trick for getting a world-class debugger for free in IE.

JavaScript debugging in Visual Web Developer ExpressSome background: users of Visual Studio have long known that it comes with an awesome debugger, probably the best JavaScript debugger there is (though Firebug is catching up fast). Whenever you get a JavaScript error, Visual Studio can connect to the Internet Explorer process and start debugging. You can pause the execution of the code, rewind and fast-forward execution, modify data held in variables and get notified when specific variables change in value. Once you're used to it, coding without a debugger makes you feel like a blind man in a dark room looking for a black cat that isn't there*.

The only problem is that it costs upwards of £500. Microsoft have released an excellent free edition of Visual Studio for web development called Visual Web Developer, but among the features reserved for the professional edition is the ability to connect to a process. Hence when you get a JavaScript error in a web page, VWD won't appear in the list of possible debuggers.
