I use Clojure for my hobby projects because: pervasive immutability applies very well to lots of things I like to work on, I have extensive experience in both Java and JavaScript (Clojure's 2 major host environments), and it's fun. The other language I really like to work in is Elixir. I use it for hobby projects where the concurrency model fits really well.
