Expo Go
Expo Go is a mobile application that allows developers to run and test React Native projects directly on physical iOS and Android devices without needing to build and install native binaries. It provides a sandboxed environment for rapid prototyping, debugging, and sharing apps during development. The tool integrates with the Expo platform to streamline the React Native workflow by handling native module compatibility and over-the-air updates.
Developers should use Expo Go when building React Native apps for quick iteration, testing on real devices, and collaborating with team members or clients without complex setup. It is ideal for prototyping, educational purposes, and projects that rely on Expo-managed workflows, as it eliminates the need for Xcode or Android Studio for basic development. However, it is not suitable for production deployments or apps requiring custom native modules outside Expo's supported libraries.
