EDIT: Also C# (so many languages, I can't even remember which ones I've used sometimes). I'm also not including TypeScript or Dart (optional static typing), which I've technically "tried", but don't know much about.
For example, in Haskell you can write code as if you're in a dynamic language without annotating all the types and yet you get all of the benefits of types. It's the best of both worlds.
Concluding that static languages suck after using java and c++ et al is a common mistake, and is understandable.
What I did say was that I can be just as productive in those languages as I am in JavaScript, if not more so. It remains to be seen whether I can gain more productivity with TypeScript or Dart.
