Zena
I'm working on a new programming language for WebAssembly GC, called Zena: https://zena-lang.dev/ It's like a fixed up TypeScript specifically tailored for Wasm GC that can produce very small and fast binaries, but also has features like pattern matching, ownership / borrow checking for resources, pipeline, tail call elimination, multi-value returns, direct WASI component integration and a lot more.
