Expo is how the large majority of new React Native projects begin, and this official tutorial is the fastest route to a finished app rather than a collection of disconnected examples. You build a small image-sharing application, and in doing so you touch the things every real app needs: screen navigation, camera roll access, device permissions, gesture handling and creating a build you can share.
It is deliberately opinionated, which is exactly what a beginner wants. Rather than pausing to explain every alternative, it makes sensible choices and keeps you moving, so you finish with working software and the confidence to start your own project.
