Expo Doc:
https://docs.expo.io/versions/latest/introduction/installation/

While Expo is great for fast prototyping and writing your app when only JavaScript code is involved, usually you will at some point add packages with native dependencies and as a result you will have to use React Native.create-react-native-app provides a mechanism of ejecting from Exponent by running npm run eject and continuing to run your application with react-native run-ios or react-native run-android.
