* Go: statically typed, no type parametrization, good support for CSP-like concurrency, deeply imperative language. Proponents site its speed of compilation, simplicity, and growing community.
* Scala: statically typed, modern and sophisticated type system, supports OO and functional programming, runs on the JVM, has good concurrency support.
I really don't know enough about Node.js to say anything about it. It's Javascript, so it's dynamic typing and a mix of OO and functional programming.
