>>105829319Windows 11 UI is written in react native/javascript, it probably compiles to native, but this overhead of javascript -> native is what make it slow, windows 11 is laggy compared to windows 10.
GJS is GNOME's "react native", it is less shitty than react native, you can tell by using gnome, it's not as slow and laggy as windows 11.
KDE is Qt (C++), but KDE shell developers are retarded, it's buggy.
React is Facebook's UI framework for web (it works by changing browser's DOM), it got ported to desktop (hence react ""native""), but it's not true native if it's written in javascript.
