# Building Mobile Apps with React Native React Native lets you build native mobile apps for iOS and Android using JavaScript and React. You write once and deploy across platforms with native-like performance. ## Main Advantages - **Single Codebase**: One project for both iOS and Android. - **Native Components**: Access camera, GPS, and more with bridging. - **Reusable Logic**: Share code with web-based React apps when feasible.
## Example Setup 1. **Install CLI**: `npm install -g expo-cli` 2. **Create App**: `expo init myApp` 3. **Run on Device**: `expo start` React Native’s ecosystem allows you to efficiently build, test, and deploy apps with minimal configuration.
