JS runs natively on the web, it embraces multiple paradigms, it has a huge community, and you can get a job in almost any city on earth if you know how to use it. Haskell may be "better" as a language, (just as Esperanto may be superior to English) but if you want the widest range of opportunities in your life and not just in your language, Javascript/English beats Haskell/Esperanto.
Why not help bring some of Haskell's concepts to a more relevant language instead of bemoaning the entirely rational decisions made by millions of junior and senior developers?
Edit: the rabid insularity of the Haskell community definitely doesn't help. The Python community was dissatisfied with JS and created Coffeescript, and as of ES6 now everyone can enjoy the fat arrow syntax. Less pleasantly, the Java community got class syntax added to ES6, but at least they're trying to contribute. I'm sure Haskell has plenty of really cool things to bring to the table, but I've never heard of any of them, because all the Haskell community wants do is talk about how JavaScript sucks instead of embracing the functional side of it.
