The #wasm folks are on the warpath to blow up the distinction. Across languages even!

#Wasi preview 3 is >80% working on an async model, one where there is no function coloring and the runtime just does the right thing.

#WebAssembly Component Model is promising, but examples are either too simple or too complex.

I built a REPL with plugins that work in both CLI & web, sandboxed by default, and the REPL logic itself compiles to #WASM.

Once again putting mental energy into thinking of how and what to do file systems on the web. I'm pretty #wasi maximalist, as desires go.

But I'm not sure if that's going to be at all usable by typescript. Short of maybe running in jco, a js SpiderMonkey engine running in wasm.

Anyone here who wrote a simple #algorithm, no matter what, in wasm/wasi in one language and than loaded the built code in another one?
I read that it is possible but I didn't see many examples
