I understand it is a VM like Java. I was just under the impression that it was somehow better, more streamlined, that would offer enough performance improvement that you could start treating it like running a 'native' local app. Like if I build a 'native' app, a 'thick client', I could now run it on WASM in a browser. Thus not need any local installs, but have same performance.

I've seen some apps doing that. But guess it isn't considered 'the way' for the future?
