Serious question, in what use cases do you see JavaScript especially (but also Python) competing in the "on top of WASM" space?

Any time I see a language that compiles directly to WASM my instinct is that it will compete with Zig, Rust or C/C++/emscripten.

In the "on top of WASM" case, I imagine that the advantage of Python and JS will be exactly the same as the "not on top of WASM case". Namely, mainly development convenience at the cost of performance.

So it's scenarios where the deployment target has to be WASM, and these languages are chosen to be used on top of it. Like some of these new FaaS clouds which are targeting WASM-only deployments, or e.g. Fastly edge compute?

That makes sense, the mention of JS got me thinking about browsers which is where I spend most of my time.
