Nim looks awesome. Does anyone know why it doesn't have first-class support for wasm? That's the only thing that would keep me from diving into it more.
I think the short answer is it's built on top of C tooling so it doesn't really need another way to do it because you can use emscripten. Search their forum for "web assembly".
I did ask him about it eight years ago: https://forum.nim-lang.org/t/1392#8675
But that was a little early on and there have been other priorities for the language.
The reason I ask is that I was poking around and saw some projects to help with wasm compilation, and on this random list of wasm-capable languages [0], Nim is listed as "Work in Progress." Notably, Swift is ranked higher, and I view Swift as extremely experimental when it comes to wasm
