If I were to pick it would be Elixir or Lua. Lua because it can be used as an embedded language and it is pretty fast for an interpreted language. Elixir because I have written tiny scripts in it and was impressed that even though it wasn't the fastest looking way of doing stuff it didn't impact the speed on the machine I was using (a low spec NUC). I feel like Elixir has the potential to keep growing and Lua is certainly a language that can get stuff done or can be embedded as that last bit that probably can be scripted instead of compiled.
