Haxe is my favorite programming language. I recommend hanging out in the Discord, the community is quite active! We have had new frameworks like Ceramic [0] popping up and one of the (imo) best UI libraries: HaxeUI [0] be continuously developed. There is a bit of unrest on the future of Haxe, but I have seen development pick back up recently.
