Expo

Expo is an open-source framework and platform for building universal native apps using JavaScript or TypeScript. It enables developers to create a single project that runs natively on Android, iOS, and the web, simplifying app development with features like live reload, managed workflows with built-in APIs (camera, location, notifications), and over-the-air (OTA) updates. Expo is ideal for developers and teams looking to quickly build and prototype cross-platform apps without deep native setup, though it has some limitations regarding app size and native module customization.
