Is there something about Erlang itself that makes it an attractive FP language for you, or is it the environment (Beam, OTP)? As a web dev, I find the performance of the system and concept of the actor model appealing and interesting, although admittedly I lack an in-depth understanding. I found the language to be too high a barrier though. This includes Elixir. http://efene.org/ looked promising, but when I tried to install it, I had some issue with something being outdated. Gleam is the next thing to try, although the more I read about it the less I understand, lol.
