It allows, for example, to create bindings as I did for raylib graphics library. exaequOS can run any program that can be built to WebAssembly It will soon support WASI p1 and p2. So many programming languages will be possible for creating programs targeting exaequOS

Is there not a way to use the browser native js execution environment for that? You lose a non-trivial amount of performance running js inside quickjs inside of wasm vs the browser native js engine. I wouldn't be surprised if that's 10 or even 20 times slower, and of course requires loading more code into the browser (slower startup, more ram usage). Maybe you don't care about that, but all of that is pretty orthogonal to the environments I an embedded engine like this is intended for.

Maybe with plugins. The WebAssembly way is cross platform. You would be very surprised with the performances of WebAssembly. I have built a Fibonacci test program in Rust that runs faster when built to Wasi than the native target on my MacBook
