Ask HN: When people say "we use Scala for our API" what do they mean?

Well for me It would mean I used Play! The fact that its built on netty (non-blocking io) and is by default async that and its Iteratee and Enumerator makes it real nice for api dev.

We use Unfiltered. Playframework/Scalatra are also considered as good alternatives.

They are clueless and don't know java is a programming language for lamers.

We use Scalatra. It doesn't do too much/get in the way.
