React Native bold fonts support PR hangs almost a year

React Native’s first principle is meeting user’s expectations of the platform. https://reactnative.dev/blog/2020/07/17/react-native-princip...

Since the platform doesn’t provide shadow support, React Native can’t provide that support on Android either. React Native’s shadow API works for the platforms that do support it, like iOS, Windows, and macOS.

Just like regular react and lots of other tools, React Native is as popular as it is because it was one of the first (and credit where credit is due, it changed the landscape), and because of corporate marketing and hype along with a generous helping of people wanting to use it to ensure they are employable.

Nativescript IMO is the better framework down to it's core, though it's ecosystem can be quite dated at times (you may come across a lib that has not been changed in years, and that may be because it works and the outstanding issues aren't deal breakers).
