It seems fair. I have an hypothesis beyond the fact that it's a niche so self-motivated people are pre-selected: what somebody needs to learn Haskell are in good part applicable to computer science and programming languages whereas for JavaScript you need to learn the quirks and the specificity of the ecosystem first. The second experience does not translate very well to solving hard problems.
