And speaking of back ends, I'd love for Kotlin to support a fourth one: Web Assembly. Rust just added support for it and a "Hello world" program is around 200 bytes (!). Much better than going through Javascript

But Web Assembly preview already part of Kotlin/Native. Or are you talking about generating webassembly binaries directly, without llvm? Does it really make sense?

Indeed, wasm is already there for quite some time. Spinner demo includes an example.

I meant “does it make any sense to generate wasm binaries directly (new Kotlin backend) instead of LLVM and convert them to wasm then how it implemented already in K/N?”

Does it have any advantage to do it manually if LLVM can do it and we have LLVM backend?
