Also keep in mind React Native is based on React repo project. On top of that you have a lot of work by community in:
- expo https://github.com/expo/expo
- react native reanimated https://github.com/software-mansion/react-native-reanimated
- react navigation https://github.com/react-navigation/react-navigation
- react native skia https://github.com/Shopify/react-native-skia
All of those packages are highly maintained and are pretty used in all RN projects and considered standard.
