A comment on Why Google Sheets ported its calculation worker from JavaScript to WasmGC. Parent comment

Great work Alon! Yet another case of impressive engineering. I have a couple of questions:

1. How is the landscape of wasmGC browser support? Given it's relatively new is it OK to use this and ship production apps now? How does sheets handle older/unsupported browsers?

2. In Google IO the Workspace team mentioned they'd leverage Kotlin Multiplatform to achieve use cases like this. I see Sheet's using the in-house J2CL compiler but is there cases where KMM is used to target WASM - in sheets or docs? What are your thoughts?

For current support, see

https://webassembly.org/features/

Chrome (and other Chromium-based browsers) and Firefox have had WasmGC enabled for a few releases now. But Safari doesn't yet last I heard.

Sheets can serve a JS version to browsers without WasmGC, since they can compile the same code to either JS or Wasm.

About Kotlin, I know they have a working WasmGC toolchain that works very well, so personally I think it is a good option in general. But I don't know offhand about current users or plans.
