This is definitely the best option in the TS ecosystem but it's not meaningfully implementing typeclasses from the perspective of the end user. There's no single `fmap` for example, instead you'll be using dedicated `Array.map`, `Option.map`, etc.

As far as i remember there's functions that take explicit typeclass dictionaries (that you can compose via contramap). So I guess they sort of do typeclasses, but without implicits, which is pretty painful IME. Example: https://gcanti.github.io/fp-ts/modules/Functor.ts.html#map
