A modern programming language that makes developers happier.

I came across multiple articles and benchmarks on the web, comparing JS and WASM performance. As I understood in mixed (WASM/JS) environment WASM can be much slower than pure JS because of data marshalling overhead. Do I have this overhead if I use Compose Multiplatform and target WASM? Are there any real world comparisons? And the main question is: Is this possible performance difference important in a general real world web application?

I'm working on an framework targeting both js and wasm, which makes lots of js interop and dom manipulations. In general the performance of simple apps compiled to wasm is better than js.
