And yet, that is not the case! While ReactNative might not result in quite as big of a performance penalty as embedding a browser engine, its performance can still be worse than actual native apps, given that it adds additional abstractions to make developer's lives easier and allow for cross-platform development: https://medium.com/swlh/flutter-vs-react-native-vs-native-de...

While one could argue that there aren't that many visually driven experiences like that out in the wild, the benchmarks still prove that most abstractions have drawbacks.

Of course, there are good reasons for using them, which is also why many choose even the previously mentioned Electron platform for development, instead of something like Qt/GTK on desktop.

But for the discussion at hand, it simply serves as a suggestion that there's more at play here than just "Java uses a lot of memory and can be slow".
