Pah. I used to program in Javascript but moved to C#, primarilly because C# is more powerful and because the IDE is frikken awesome.

I also utterly don't understand why anyone would want to program in dynamic languages and lose the static type system. I mistype stuff all the time, and I really like the fact that my compiler will tell me I made a dumb mistake rather than finding out later during testing, or worse, via customer support.
