Expo Application Services (EAS) is the cloud toolchain for production React Native apps. It handles complex native builds, app store submissions, and over-the-air updates. The main footgun is confusing it with the local `expo` CLI for development.
Expo Application Services (EAS) is the cloud toolchain for building, deploying, and updating production React Native apps, handling native complexities so you don't have to.
