Really give it a go! It is beyond worldly. If you think Typescript is great, then ocaml/f# will make it look inferior.
If you're doing React + Typescript give Reasonml which is a syntax sugar on top of Ocaml that compiles using bucklescript a go. Ocaml has the fastest compiler out there.
How’s the tooling for that? Haskell has the “best” compiler and garbage tooling that should be built on top of the ol’ rolls Royce engine it’s rocking on.
Meanwhile the plugins and IDE integrations for Reason/Ocaml and F# are ready to go from the start and work pretty well.
