# React Native

React Native lets you build native apps using [React](https://react.dev/). Written
in JavaScript, rendered with native code.

- **Native UI.** React Native primitives render to native platform UI, meaning your app
  uses the same native platform APIs other apps do. Gestures, text scaling, and
  accessibility behave the way users expect on each OS.
- **React, everywhere.** Declarative UI, components, hooks, and Suspense, reused
  across Android, iOS, and [other platforms](https://reactnative.dev/docs/out-of-tree-platforms).
- **Developer Velocity.** See local changes in seconds. Changes to JavaScript code are applied with Fast Refresh, without rebuilding the native app.
- **Extend it yourself.** Native Modules let you call platform code directly from JavaScript, synchronously and type-safe — or reach for [thousands of existing libraries](https://reactnative.directory/).

React Native is developed and supported by many companies and individual core contributors. Find out more on the [React Foundation website](https://react.foundation/).

## Building your first React Native app

Follow the [Getting Started guide](https://reactnative.dev/docs/environment-setup) for a new app, or [Integration with Existing Apps](https://reactnative.dev/docs/integration-with-existing-apps) to adopt React
