> Also, its very strange to see these concepts illustrated with Javascript. I imagine thats something like trying to learn Chinese using the roman alphabet. Not that it can't be done, but a lot of important details are necessarily missing.

I think you're being sincere in expressing a common attitude within the Lisp/FP community, but it's an unfortunately limiting attitude. It would appear strange to an ancient Sumerian to see the Epic of Gilgamesh translated into English, but the translation is far more accessible and thus far more influential than the original.

I'm a front-end dev and I got into Clojure and Elm because of some books/libraries for functional programming in Javascript. It's doubtful I would've ever had enough interest to learn if no one in those communities made an effort to translate some of their concepts into a language that I already use.
