JavaScript, even more so than VB, has to be the Rodney Dangerfield of programming languages. I'm going to blow whatever credibility I might have by saying "I actually like programming in JavaScript." I'm actually building a lot of the screens in StoryTeller with JavaScript running in a WebBrowser control because I think I can do dynamic layout much faster with JavaScript than a WinForms screen. Besides, the point of a "side" project is to do stuff you don't get to do at your day job.
