If I remember correctly, there is a project to create an Ada-to-WASM (Web Assembly) compiler (via LLVM? I am not sure).
Anyway, if such project exists and someone here is involved, I would like to point out to the fairly new Web Assembly builders community [1]. I just registered, but I think that it would be nice to have someone involved in the Ada-to-WASM project.
