04/03/2023, 3:15 PMCurrently when you use "onWasmReady" only skiko (skia + kotlin bindings) part is wasm.
With 1.8.20 k/wasm, we'll be able to compile Compose to wasm too. Currently (with k/js) it's compiled to js.

04/03/2023, 6:24 PMI have a hard time picturing what that means for developer and user experience. Is it preferred over js and if so why? I'm missing a larger picture: when do I want kotlin js and when wasm?

04/03/2023, 6:26 PMTo me personally anything is preferable over js... But for most it will be the abscence of js kinks that es built in over the years
