You should perhaps focus on adding value to the discussion, than going on about people you hardly know anything about. JS and Python offer comparable expressiveness for most programming tasks: basic imperative language features, first class functions, closures etc. If you miss list comprehensions, a better syntax for lambdas or classes, go ahead and use the favorite JS shorthand - coffeescript. It _really_ is JS. Even if you don't use coffee, having first class functions would let you write some of those missing features in a library (albeit with a slightly clunkier syntax). Sure there are nuances, like scoping rules. On the plus side, having a single programming language on the server and client saves some time. Also, most of the libraries being async in nature helps in typical I/O heavy apps. I draw these inferences from a medium sized JS project I have going on at http://www.poe3.com http://www.poe3.com (source: https://github.com/jeswin/poetry-source https://github.com/jeswin/poetry-source). I am fairly convinced that JS did save me a lot of time. Interested in seeing how you came to your conclusions.
