Misleading on the comment, LG WebOS is using EnactJS (Framework on top of ReactJS) + Chromium Embedded Browser, not native, just webapp on browser.

But React Native is different , JS code compiled to native code using c/c++ compiler on target system. Flutter also do like this one.

Embedded browser is slower than native app, because extra browser layer than native one.

Sure, but you're compiling two radically different languages. JavaScript is dynamically typed (even with TypeScript) and Dart has a sound static type system.

It's much easier to compile Dart to efficient native code than it is JavaScript.
