There is AssemblyScript, a more basic language targeting WASM directly. https://www.assemblyscript.org/ https://www.assemblyscript.org/ AssemblyScript seems like it can become the Cython for TypeScript - close enough to mainline TS that you could consider porting or lowering some of your existing application for performance. However as a WASM only language, the use cases are quite specific. I think I would prefer to rewrite slow algos in Rust, where they could be re used natively in a wider variety of contexts like inside a native app or in a native Rust backend service.
