Had to add this because I thought it was fairly obvious, but all the other Scala mentions were either snarky or seemed to miss the core point of the title of the post : "What languages fix"

Scala : functional programming without leaving the JVM

Because enterprises have spent a decade or so building up JVM expertise in the form of Java.

Scala is really a multi-paradigm language, and that is arguably one of its major selling points. While you can use it exclusively for functional programming if you wish, object-oriented and imperative programming are equal citizens.

Scala is much more than a functional language, its more like Java done much better, not all of its useful features are functional. Maybe you meant clojure?

You're right! It's not AS simple as I made it out to be.
