I would argue that if you want to make an honest comparison than use an implementation that at least makes an effort to optimize functional code. And JS does jack shit for FP code compared to Haskell.

No idea what your comment about jack shit is about. Haskell is often just as bad as Ramda.

Edit. By the way. All the unusable and unreadable jargon that Haskell uses can be much more easily explained with Javascript: https://github.com/hemanth/functional-programming-jargon Make of it what you will
