While I can't say that I am a big fan of the Haskell community, I fully understand why they see how extending Javascript is never going to work out: You can't just bolt Hindley-Milner to a language with prototypical inheritance, so the functional part of Javascript just doesn't help at all. This is why instead, for the web, they have Purescript, which compiles down to Javascript, but it doesn't look like Javascript.

Not quite coming from the Haskell community, but heavily inspired by parts of Haskell is Elm, which you might have heard about. It has the best compiler errors ever, it takes immutability seriously, and is far nicer IMO than either Purescript or Javascript for web development.

It's really an issue of types. Languages like Java, Python and Javascript don't have quite the same approach to types, but their worldviews there are not that different. Anything coming from the ML family just isn't going to translate, and that is going to happen regardless of how insular the communities might be. Existing Javascript features actively make most of the things a Haskell programmer would want just not work at all. This is why you hear them talk about how Javascript sucks: Everything they'd want involves taking things out first, and that is never going to happen.

So don't blame in on the community here, bad as some elements might be: The differences just cannot be negotiated away. You might as well ask people to open their mind and breathe carbon dioxide and sulfur so they can go visit you in Venus: It's a barrier that is too hard to be worth crossing in either direction. Trying to add Javascript or Python features to Haskell would get you in a similar boat.

It's written in Haskell. How much more "coming from the Haskell community" could it be?
