Elixir is a nice functional language. Not as purely functional as Haskel mind.

It is based off of Erlang and runs on the Erlang VM. Syntax is Ruby inspired. It is not a high performant language (like C, Rust, etc), but it excels at distributed computing and fault tolerance. There is excellent documentation and tooling for it as well.

Same here: too lazy to fiddle around with stuff. It works, is Arch based, and satisfies my needs
