I don't have any production experience with Scala but I played around a little bit. It's a thoroughly modern language which can use all these Java libraries produced over the years so what's not to like. The only reason I'm not using it is that my professional Java-related tasks tend to be small enough that pulling in an extra dependency is an overhead. Mind you, I haven't looked at Clojure or Kotlin, both of which offer the same benefits I find attractive in Scala.
