Expo is a third-party service. It removes a lot of complexity, and provides lots of convenience & utility features.
In other words, It is a thin extra layer between your app and the vanilla React Native.
For detail, you can find the first step here “https://expo.io/learn“.
React Native CLI
You can do fine-grained control for raw React Native app. However, you need to setup/manage development environment manually…
It requires high skills and deep knowledge about developments.
Which is Better?
For beginners, definitely “Expo CLI Tool“. Because it’s so much more convenient!
Then, if you need the full flexibility for some reasons, you can switch to “React Native CLI" by “eject“.
