I am Software Developer, currently interested in static type languages (TypeScript, Elm, ReScript) mostly in the frontend land, but working actively in Python also. I am available for mentoring.
FP is harder, try to do typing for pipe, compose or curry. Trivial in JS hard in TS. Or try to represent polimorhic FP abstractions like functors. You can do it but you need to create typing for every Functor instance, you cannot easily do it without some HKT hacks available there. If you don't believe me check how look Ramda types declarations.
Yes you can fallback to unsound type like any but then we get type wholes and less compiler help.
For the second, I don't think anybody today is considering using procedures (void functions), and not use a bit of functional or oop abstractions in the code. So no I didn't confuse anything.
Thank you for your comment.

With TypeScript 4 they alleviated the pain involved in typing e.g. ramda pipe a bit! They introduced variadic tuple types 🎉
