Really impressive to pull this off! I think it's great to see more fp inspired libraries popping up in a lot of places, especially for languages that are "known to ship" and where you can apply fp programming patterns in an incremental style instead of going "all in" with a pure fp language. The more I'm exposed to fp concepts, the more I think we have a lot to win with exposing more and potential alien programmers to the subject to pick up the good parts. I can recommend fp-ts in case you're doing web stuff, their either implementation looks nicer and it's in active support. type Either<E, A> = Left<E> | Right<A>
