I have got to know a few small teams in my local area, developing in niche languages (including Haxe and Dart), and they do not talk about it on forums or on meetups. They are busy developing their product, and the platform's the quality and features help them, the performance is good, and they don't care what the rest of the world thinks with the current hype trends that would fade soon anyway. I lost track how many times I've heard my friends cursing JS and even TypeScript, and telling me they wish they could use a sane language instead. Well, you actually can, and I believe should.
