yeah, but I feel they have a reason to exist. Clojure exists because it has interesting ideas about immutability, and is a lisp. Elm exists because FP. This exists because... Why? They thought we needed a new syntax for JSX? They thought we needed another language that was kind of like coffescript, but different in subtle ways? I don't know, and I can't see what this is bringing to the table.
Then don't use it? There's no reason to bash on anyone for making something, even if it's absolutely useless:
Sorry, I didn't mean to bash on them for making. Let me clarify my opinion. What annoys me is that they made a thing, which is of debatable use, and talked it up as the next big thing, which everyone should use, because it's amazing. That bugs me.
Pretty sure they are still considered new or at least exotic from a "typical" developer's point of view.
