IMHO it would fit use cases of java, mostly long running services. But it is a hosted language with different implementations on top of javascript, .net etc. So it might branch out other use cases like frontend dev. It has a small but active community. Although it might be most popular lisp nowadays.

If you are not familiar with lisp and aim is having fun while learning new things then clojure will fit nicely. It is so joyful once you get the initial weirdness because it will feel different. You just fire up a REPL, leave it running in background, hook your ide/editor to it and start sending evals. The application grows while it is running. I find the workflow quiet enjoyable.
