I'm completely unsure what quality of javascript makes it suitable for writing high performance systems.
Is it single threading?
Is it the weird typeof crap you have to do to check if a variable is defined?
Is it the lack of integers?
Is it the prototyping system?
Node.js to me looks like a slightly better syntax than the horribly ugly C# async calls. (Not the new async/wait system). Javascript completely pales in comparison to F# or Haskell in terms of readability of async code.
If you prefer non-functional languages it would seem that Go would be a much better place to start for performance than Javascript. Or clojure or scala.
Sure node.js outperforms rails, but rails isn't designed around being the fastest webserver ever.
