What is Expo?
Expo offers mobile infrastructure for developing, validating, deploying, and monitoring applications across iOS, Android, and web platforms. It provides a unified codebase approach, allowing development teams to build and ship applications efficiently. Developers use Expo to build applications, test them on devices or simulators, and deploy them to app stores or as over-the-air updates. The platform includes tools for automating builds, tests, and releases, along with built-in monitoring and observability features to track app behavior in production.
