TypeScript is much less readable than Haskell and OCaml, but you can easily find translations to TypeScript such as https://github.com/skeate/lambdata.

That's like saying that Norwegian is much less readable than Italian. It is in the eye of the beholder. They can both express the same concepts but which one is more readable depends on which one you already know.
Only in the turing tarpit sense. Out of the box, they have very different capabilities. For example:
Higher-kinded types: easy in Haskell, hard in OCaml, mostly impossible in Typescript.
First-class modules: OCaml has them, Typescript can sort of simulate them with extraordinarily unsafe prototype mangling stuff that you should never ever use, impossible in Haskell
Open variants: Easy in OCaml and Typescript, hard in Haskell
