That looks really interesting. I'm curious, are there any performance drawbacks to updating DOM via WebAssembly or is it negligible? I.e. let's say you are building an editor of some kind. If the entire app is in Go, that means sending the keydown event to the WASM module and having it update HTML back. Is it not better (from performance perspective) to just use JavaScript all the way?
