FRP is a fascinating paradigm, but I find I really have to turn my brain inside-out to "get" it. But it's really cool to have UIs that are completely consistent.

The funny thing is that good ole MVC also gave us UIs that are completely consistent.

I learn FP throught ELM and I really enjoyed it. Unfortunately the language seems dead.

What are the easiest FP language to learn ? I checked multiple time Haskell but it seems really hard

I have been using rxjs with typescript for some stuff. Functional reactive has proven to be a good paradigm for some stuff in the UI and thornier parts of shared state across multiple applications.

Proper FP as in pure functional programming?

Probably Purescript in the frontend (also hard) or Scala on the backend (easier, because you can also write impure code).

Not really. It's just that at the time, SPAs and concurrent requests were not really a thing or only used rarely.

F# might be a good shout.

Yeah but for a limited subset of desirable functionality. It sucks to use for something where you want a dynamic UI.
