# 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 Native incrementally.
### Using a Framework
We believe that the best way to experience React Native is through a Framework, a toolbox with all the necessary APIs to let you build production ready apps. [Expo](https://docs.expo.dev/get-started/set-up-your-environment/) is a production-grade React Native Framework, with file-based routing, a standard library of native modules, and much more.
To create a new Expo project, run the following in your terminal:
npx create-expo-app@latest
Then follow the rest of [Expo's getting started guide](https://docs.expo.dev/get-started/set-up-your-environment/) to start building.
### Without a Framework
You can also use React Native without a Framework, however we've found that most developers benefit from one — navigation, native dependencies, and platform tooling are problems the ecosystem has already solved. If a Framework doesn't suit your app, follow [Getting Started Without a Framework](https://reactnative.dev/docs/getting-started-without-a-framework).
