React Native brings [**React**'s][r] declarative UI framework to iOS and Android. With React Native, you use native UI controls and have full access to the native platform. - **Declarative.** React makes it painless to create interactive UIs. Declarative views make your code more predictable and easier to debug. - **Component-Based.** Build encapsulated components that manage their state, then compose them to make complex UIs. - **Developer Velocity.** See local changes in seconds. Changes to JavaScript code can be live reloaded without rebuilding the native app. - **Portability.** Reuse code across iOS, Android, and [other platforms][p]. React Native is developed and supported by many companies and individual core contributors. Find out more in our [ecosystem overview][e].

You may use Windows, macOS, or Linux as your development operating system, though building and running iOS apps is limited to macOS. Tools like Expo can be used to work around this. 🎉 Building your first React Native app Follow the Getting Started guide. The recommended way to install React Native depends on your project. Here you can find short guides for the most common scenarios: - [Trying out React Native][hello-world] - [Creating a New Application][new-app] - [Adding React Native to an Existing Application][existing] [hello-world]: https://snack.expo.dev/@samples/hello-world [new-app]: https://reactnative.dev/docs/getting-started [existing]: https://reactnative.dev/docs/integration-with-existing-apps 📖 Documentation The full documentation for React Native can be found on our [website][docs]. The React Native documentation discusses components, APIs, and topics that are specific to React Native. For further documentation on the React API that is shared between React Native and React DOM, refer to the [React documentation][r-docs]. The source for the React Native documentation and website is hosted on a separate repository, [**@facebook/react-native-website**][repo-website].
