I think BQN is a lot of fun, it is an array language like APL, but it does some things different https://mlochbaum.github.io/BQN/ the documentation is great.

Dyalog APL is more of an actual APL, https://www.dyalog.com/

There is also J https://www.jsoftware.com/#/

The array language community on discord "The Apl Farm" (https://discord.gg/SDTW36EhWF) is pretty active.

I also love the Arraycast podcast https://www.arraycast.com/ many amazing interviews and interesting discussions.
