Ultimate Guide to React Native: Learn App Development Step-by-Step

React Native is a widely used framework for developing cross-platform mobile applications. This framework allows developers to create native mobile apps for multiple platforms simultaneously. With React Native, you can develop full-fledged mobile applications for both iOS and Android using a single programming language—JavaScript. This is a significant advantage because it saves development time and cost while avoiding the steep learning curves associated with platform-specific native languages such as Java or Kotlin for Android, and Swift or Objective-C for iOS.

React Native is not just a web technology wrapped inside a mobile app; it generates real native applications. It leverages native components under the hood, making it possible to deliver high-performance mobile experiences.

What is React Native?

React Native is an open-source JavaScript framework created to build mobile apps that work on both iOS and Android. The key idea behind React Native is to allow developers to write the code once and deploy it on multiple platforms without rewriting the app for each operating system.

The framework was first released by Facebook in March 2015 and has since evolved through contributions from both the community and corporate users. It provides a consistent and efficient way of building user interfaces by using components that map directly to native UI elements.

How React Native Works

React Native uses JavaScript to describe the user interface and the app’s logic. This JavaScript code interacts with native platform APIs through a bridge, which translates JavaScript commands into native calls. This approach allows React Native to deliver a native-like performance and appearance, unlike traditional hybrid frameworks that rely on web views.

The UI components in React Native correspond directly to native UI widgets on iOS and Android. For example, a <View> in React Native corresponds to a UIView in iOS and a View in Android. This direct mapping ensures a native look and feel for the applications.

Why Use React Native?

Cross-Platform Development

One of the most significant benefits of React Native is its ability to build apps that run on both iOS and Android platforms using a shared codebase. This drastically reduces the development time and effort since you don’t need to write separate code for each platform. Minor platform-specific tweaks can be implemented when necessary.

JavaScript as the Development Language

React Native uses JavaScript, one of the most popular programming languages worldwide. This choice makes the framework accessible to a wide pool of developers, especially those with web development experience. It eliminates the need to learn platform-specific languages such as Kotlin, Swift, or Objective-C, which can have steeper learning curves.

Performance

React Native apps perform nearly as well as native apps because they use native components for the user interface. The bridge that connects JavaScript and native code is efficient, and React Native also offers features like hot reloading, which allows developers to see code changes instantly without restarting the app. This accelerates development and testing cycles.

Large Developer Community and Continuous Improvement

The React Native community is vast and active, ensuring robust support for developers. Community contributions regularly add new features, fix bugs, and improve the framework’s performance and capabilities. This vibrant ecosystem also offers numerous libraries, tools, and third-party plugins to extend app functionalities easily.

Adoption by Industry Leaders

Many well-known companies have adopted React Native to build their mobile apps due to its advantages in speed, cost-effectiveness, and performance. The popularity of React Native is reflected in the growing demand for skilled React Native developers in the job market.

Core Concepts of React Native

Before diving into the practical part of creating a React Native application, it is essential to understand some fundamental concepts that the framework uses.

Components

In React Native, the entire user interface is composed of components. Components are reusable building blocks that define parts of the UI. Components can be functional or class-based, and each component manages its state and properties.

JSX Syntax

React Native uses JSX, a syntax extension for JavaScript, which allows developers to write HTML-like code within JavaScript. JSX simplifies the creation of UI components by combining markup and logic in one place.

State and Props

Two important concepts to understand in React Native are state and props.

  • State: State holds data that can change over time within a component. When the state changes, the component re-renders to reflect the updated data. 
  • Props: Props (short for properties) are used to pass data from one component to another. Unlike state, props are immutable within the component receiving them. 

Styling

React Native uses JavaScript for styling components. Styling is done through a style prop, which takes an object containing style rules similar to CSS but written in camelCase instead of kebab-case. Developers can use inline styles or a StyleSheet component to define styles.

View

The View component is the fundamental building block for layout and structure in React Native. It acts as a container that supports styling, layout, touch handling, and accessibility features. It maps directly to the native view components on both Android and iOS.

React Native Vs. Platform-Specific Apps

It’s useful to compare React Native applications with platform-specific apps to understand their strengths and trade-offs.

React Native Platform-Specific
Cross-platform: works on iOS & Android Designed for a single platform (iOS or Android)
Developers usually come from web backgrounds Developers have strong platform-specific knowledge
Faster build time Slower build time
Ideal for simple to moderately complex apps Suitable for complex apps requiring full platform capabilities
Suited for smaller teams with limited resources Requires experienced teams with extensive resources
Continuous updates from the community Long-term support guaranteed by platform owners

React Native offers an excellent balance between development speed and app performance, especially when building apps targeting both platforms without complex native integrations.

Prerequisites for Learning React Native

To get the most out of React Native, some foundational knowledge is beneficial.

You should be familiar with basic programming concepts like functions, objects, arrays, and classes. A solid understanding of JavaScript is essential since React Native development revolves around it. Familiarity with HTML and CSS is helpful, especially because React Native’s styling system borrows heavily from CSS concepts. Additionally, if you have experience working with React for web development, many concepts like components, state, and props will already be familiar.

Having these skills will enable you to quickly adapt to React Native development and understand the tutorials and examples more easily.

Setting Up the Development Environment

To build React Native applications, you need to set up your development environment. The easiest way to get started is by using the Expo framework. Expo is a set of tools built around React Native that simplifies development, building, and deploying applications.

Installing Node.js

Node.js is a JavaScript runtime required to run React Native commands and manage packages. You can download and install Node.js from its official website.

Installing Expo CLI

Expo CLI is a command-line tool used to initialize and manage React Native projects using Expo. Once Node.js is installed, you can install Expo CLI globally using the following command in your terminal or command prompt:

nginx

CopyEdit

npm install -g expo-cli

 

Creating a New React Native Project

After installing Expo CLI, you can create a new React Native project by running:

csharp

CopyEdit

expo init todo-app

 

During the setup, choose the blank template with Expo workflow features included.

Navigate into your project folder with:

bash

CopyEdit

cd todo-app

 

Start the development server by running:

sql

CopyEdit

npm start

 

This command will open a browser tab with the Expo developer tools.

Previewing the App

You have two options to preview the app:

  • Run the app on an Android emulator, which requires installing Android Studio. 
  • Use the Expo Go app on your physical Android device to scan the QR code displayed in the Expo developer tools. This allows you to run the app directly on your phone. 

Choosing a Code Editor

You will also need a code editor for writing your React Native code. Visual Studio Code is a popular choice due to its features and extensions, but you can also use other editors such as Atom or Sublime Text.

With your development environment set up, you are ready to start building your React Native app.

1. React Native Navigation: Managing Screen Transitions

Mobile applications usually consist of multiple screens, and managing navigation between these screens is a critical aspect of app development. React Native does not include built-in navigation components, so developers commonly rely on third-party libraries such as React Navigation or React Native Navigation.

React Navigation Overview

React Navigation is a popular and flexible routing library designed for React Native apps. It supports several types of navigators:

  • Stack Navigator: Manages a stack of screens (like a call stack) where users can push and pop screens. 
  • Tab Navigator: Implements bottom or top tab bars for switching between different sections. 
  • Drawer Navigator: Provides a side menu for app-wide navigation. 

Setting Up React Navigation

To install React Navigation, you generally run:

npm install @react-navigation/native

npm install react-native-screens react-native-safe-area-context

 

For stack navigation:

npm install @react-navigation/native-stack

 

Then, configure the navigation container in your app’s root component:

import { NavigationContainer } from ‘@react-navigation/native’;

import { createNativeStackNavigator } from ‘@react-navigation/native-stack’;

 

const Stack = createNativeStackNavigator();

 

export default function App() {

  return (

    <NavigationContainer>

      <Stack.Navigator>

        <Stack.Screen name=”Home” component={HomeScreen} />

        <Stack.Screen name=”Details” component={DetailsScreen} />

      </Stack.Navigator>

    </NavigationContainer>

  );

}

 

Navigating Between Screens

Inside a screen component, you use the navigation prop to programmatically move between screens:

function HomeScreen({ navigation }) {

  return (

    <Button

      title “Go to Details”

      onPress={() => navigation.navigate(‘Details’)}

    />

  );

}

 

React Navigation handles the animations and back button behavior natively on both iOS and Android.

2. State Management in React Native: Beyond useState

As apps grow in complexity, managing state purely with React’s useState can become cumbersome. For larger apps, state management libraries like Redux, MobX, or Recoil are often used.

Redux

Redux is a predictable state container widely used for complex applications. It maintains a single source of truth (the store), where the entire app’s state lives. Changes to the state occur via actions and reducers.

Core Concepts of Redux:

  • Store: The object holding the app state. 
  • Actions: Plain objects describing what happened. 
  • Reducers: Pure functions that specify how the state changes in response to actions. 
  • Dispatch: The method to send actions to the store. 

Setting Up Redux in React Native

Install Redux and React Redux:

npm install redux react-redux

 

Create a reducer:

const initialState = { count: 0 };

 

function counterReducer(state = initialState, action) {

  switch (action.type) {

    case ‘INCREMENT’:

      Return { count: state.count + 1 };

    Case ‘DECREMENT’:

      Return { count: state.count – 1 };

    Default:

      return state;

  }

}

 

Create the store:

import { createStore } from ‘redux’;

const store = createStore(counterReducer);

 

Wrap your app in the Provider component to pass the store:

import { Provider } from ‘react-redux’;

 

export default function App() {

  return (

    <Provider store={store}>

      <YourMainComponent />

    </Provider>

  );

}

 

Use the Redux hooks inside components:

import { useSelector, useDispatch } from ‘react-redux’;

 

function Counter() {

  const count = useSelector(state => state.count);

  const dispatch = useDispatch();

 

  return (

    <>

      <Text>{count}</Text>

      <Button title=”Increment” onPress={() => dispatch({ type: ‘INCREMENT’ })} />

      <Button title=”Decrement” onPress={() => dispatch({ type: ‘DECREMENT’ })} />

    </>

  );

}

 

Alternatives: Context API and Recoil

For simpler global state needs, React’s Context API can suffice. Recoil is a newer library designed for state management with an easier learning curve and better performance for certain use cases.

3. Networking and API Integration

Most mobile apps interact with remote servers to fetch or send data. React Native developers use standard web APIs, such as fetch, or third-party libraries like Axios for networking.

Using the fetch API

Fetch is built into JavaScript and widely used for making HTTP requests.

Example of a GET request:

import React, { useEffect, useState } from ‘react’;

import { View, Text, ActivityIndicator } from ‘react-native’;

 

export default function UserList() {

  const [users, setUsers] = useState([]);

  const [loading, setLoading] = useState(true);

 

  useEffect(() => {

    fetch(‘https://jsonplaceholder.typicode.com/users’)

      .then(response => response.json())

      .then(data => {

        setUsers(data);

        setLoading(false);

      })

      .catch(error => {

        console.error(error);

        setLoading(false);

      });

  }, []);

 

  if (loading) {

    return <ActivityIndicator size=”large” />;

  }

 

  return (

    <View>

      {users.map(user => (

        <Text key={user.id}>{user.name}</Text>

      ))}

    </View>

  );

}

 

Using Axios

Axios provides a simpler and more feature-rich HTTP client.

Install Axios:

npm install axios

 

Example:

import axios from ‘axios’;

 

axios.get(‘https://jsonplaceholder.typicode.com/users’)

  .then(response => console.log(response.data))

  .catch(error => console.error(error));

 

4. Handling User Input and Forms

Collecting input from users is fundamental in apps. React Native provides several components for this purpose, primarily TextInput.

Basic TextInput Usage

import React, { useState } from ‘react’;

import { TextInput, View, Text } from ‘react-native’;

 

function InputExample() {

  const [text, setText] = useState(”);

 

  return (

    <View>

      <TextInput

        style={{ height: 40, borderColor: ‘gray’, borderWidth: 1 }}

        placeholder “Type here”

        value={text}

        onChangeText={setText}

      />

      <Text>You typed: {text}</Text>

    </View>

  );

}

 

Form Validation

You can add validation logic either manually or use libraries like Formik with Yup for robust form handling and schema validation.

Install Formik and Yup:

npm install formik yup

 

Example:

import React from ‘react’;

import { Button, TextInput, View, Text } from ‘react-native’;

import { Formik } from ‘formik’;

import * as Yup from ‘yup’;

 

const SignupSchema = Yup.object().shape({

  email: Yup.string().email(‘Invalid email’).required(‘Required’),

  password: Yup.string().min(6, ‘Too Short!’).required(‘Required’),

});

 

export default function SignupForm() {

  return (

    <Formik

      initialValues={{ email: ”, password: ” }}

      validationSchema={SignupSchema}

      onSubmit={values => console.log(values)}

    >

      {({ handleChange, handleBlur, handleSubmit, values, errors, touched }) => (

        <View>

          <TextInput

            placeholder “Email”

            onChangeText={handleChange(’email’)}

            onBlur={handleBlur(’email’)}

            value {values.email}

            keyboardType=”email-address”

            autoCapitalize=”none”

          />

          {errors.email && touched.email && <Text>{errors.email}</Text>}

 

          <TextInput

            placeholder “Password”

            onChangeText={handleChange(‘password’)}

            onBlur={handleBlur(‘password’)}

            value {values.password}

            secureTextEntry

          />

          {errors.password && touched.password && <Text>{errors.password}</Text>}

 

          <Button onPress={handleSubmit} title=”Submit” />

        </View>

      )}

    </Formik>

  );

}

 

5. Accessing Native Device Features

React Native provides APIs and community modules to access native device features like the camera, GPS, accelerometer, and more.

Permissions

Starting with Android 6.0 (API 23), apps must request permissions at runtime.

React Native’s PermissionsAndroid API helps manage Android permissions:

import { PermissionsAndroid } from ‘react-native’;

 

async function requestCameraPermission() {

  try {

    const granted = await PermissionsAndroid.request(

      PermissionsAndroid.PERMISSIONS.CAMERA,

      {

        title: “Camera Permission”,

        message: “This app needs access to your camera”,

        buttonNeutral: “Ask Me Later”,

        buttonNegative: “Cancel”,

        buttonPositive: “OK”

      }

    );

    if (granted === PermissionsAndroid.RESULTS.GRANTED) {

      console.log(“Camera permission granted”);

    } else {

      console.log(“Camera permission denied”);

    }

  } catch (err) {

    console.warn(err);

  }

}

 

For iOS, you declare permissions in the Info.plist file.

Using Community Modules

Camera

Use react-native-camera or expo-camera (if using Expo) to access camera functionalities.

Example with Expo Camera:

import React, { useState, useEffect, useRef } from ‘react’;

import { View, Button } from ‘react-native’;

import { Camera } from ‘expo-camera’;

 

export default function CameraExample() {

  const [hasPermission, setHasPermission] = useState(null);

  const cameraRef = useRef(null);

 

  useEffect(() => {

    (async () => {

      const { status } = await Camera.requestCameraPermissionsAsync();

      setHasPermission(status === ‘granted’);

    })();

  }, []);

 

  if (hasPermission === null) return <View />;

  if (hasPermission === false) return <Text>No access to camera</Text>;

 

  const takePicture = async () => {

    if (cameraRef.current) {

      const photo = await cameraRef.current.takePictureAsync();

      console.log(photo.uri);

    }

  };

 

  return (

    <View style={{ flex: 1 }}>

      <Camera style={{ flex: 1 }} ref={cameraRef} />

      <Button title=”Take Picture” onPress={takePicture} />

    </View>

  );

}

 

Geolocation

React Native includes Geolocation for getting location data.

navigator.geolocation.getCurrentPosition(

  position => {

    console.log(position.coords.latitude, position.coords.longitude);

  },

  Error => console.error(error),

  { enableHighAccuracy: true, timeout: 20000, maximumAge: 1000 }

);

 

For advanced location features, third-party libraries like react-native-geolocation-service are preferred.

6. Performance Optimization

Use Pure Components and React. memo

Avoid unnecessary re-renders by using React memo for functional components or PureComponent for class components.

const MyComponent = React.memo(function MyComponent({ prop }) {

  return <Text>{prop}</Text>;

});

 

Optimize Images

Large images can slow down the app. Use optimized formats and sizes. Libraries like react-native-fast-image provide better caching and performance.

Avoid Inline Functions and Objects

Inline objects and functions cause unnecessary re-renders due to reference changes. Define styles with StyleSheet.create and functions outside render or memoize them.

Use InteractionManager for Expensive Tasks

Heavy computations or animations should be deferred until interactions are complete.

import { InteractionManager } from ‘react-native’;

 

InteractionManager.runAfterInteractions(() => {

  // Expensive task here

});

 

Minimize Overdraw

Avoid excessive overlapping views to reduce GPU load.

7. Animations in React Native

Animations improve user experience by providing feedback and guiding attention.

Animated API

React Native provides the Animated API for performant animations.

Example: Fade-in effect

import React, { useRef, useEffect } from ‘react’;

import { Animated, View, Text } from ‘react-native’;

 

function FadeInView(props) {

  const fadeAnim = useRef(new Animated.Value(0)).current;

 

  useEffect(() => {

    Animated.timing(fadeAnim, {

      toValue: 1,

      duration: 1000,

      useNativeDriver: true,

    }).start();

  }, [fadeAnim]);

 

  return (

    <Animated.View style={{ …props.style, opacity: fadeAnim }}>

      {props.children}

    </Animated.View>

  );

}

 

export default function App() {

  return (

    <FadeInView style={{ flex: 1, justifyContent: ‘center’, alignItems: ‘center’ }}>

      <Text>Fading in</Text>

    </FadeInView>

  );

}

 

Reanimated Library

For more complex animations, React Native Reanimated offers better performance and smoother animations by offloading work to the native thread.

8. Testing React Native Applications

Unit Testing

Use Jest, the default test runner with React Native, for testing functions and components.

Example test:

import React from ‘react’;

import renderer from ‘react-test-renderer’;

import MyComponent from ‘../MyComponent’;

 

test(‘renders correctly’, () => {

  const tree = renderer.create(<MyComponent />).toJSON();

  expect(tree).toMatchSnapshot();

});

 

Integration and UI Testing

  • React Native Testing Library helps simulate user interactions. 
  • Detox provides end-to-end testing on real devices or emulators. 

9. Deploying React Native Apps

Building for Production

  • For iOS, use Xcode to archive and upload apps to the App Store. 
  • For Android, use Gradle commands or Android Studio to generate a signed APK or App Bundles for the Play Store. 

Using Expo for Easier Deployment

Expo offers Expo Application Services (EAS) for building and submitting apps without native code knowledge.

10. Best Practices and Tips for React Native Development

  • Modularize code: Break down UI into reusable components. 
  • Use PropTypes or TypeScript: Add type safety for better maintainability. 
  • Handle errors gracefully: Show user-friendly messages and fallbacks. 
  • Optimize for accessibility: Use accessible, accessibilityLabel, and similar props. 
  • Keep dependencies up to date: Regularly update libraries for bug fixes and new features. 
  • Monitor app performance: Use tools like React DevTools and Flipper for debugging. 

Mastering React Native involves understanding its navigation patterns, state management options, networking techniques, and access to native device features. Performance optimization, animations, testing, and deployment are equally important for delivering smooth, maintainable, and scalable applications.

By combining the power of JavaScript, the flexibility of React components, and native platform capabilities, React Native empowers developers to build high-quality mobile apps efficiently. The ecosystem’s rapid growth and vibrant community ensure that tools, libraries, and best practices continue to evolve, making React Native a top choice for cross-platform mobile development.

Final Thoughts on Mastering React Native Development

React Native has transformed the way mobile applications are built, offering a powerful blend of native performance and cross-platform flexibility. As we conclude this comprehensive guide, it’s important to reflect on the journey of learning React Native and to consider some key takeaways, best practices, and future directions for your development career.

The Power of Cross-Platform Development

One of React Native’s greatest strengths is its ability to enable developers to write a single codebase that runs on both iOS and Android platforms. This capability significantly reduces development time and maintenance overhead compared to developing two fully separate native apps. For businesses, this means faster time to market and cost savings, while for developers, it means the opportunity to reach a wider audience without having to master two completely different programming environments.

However, while React Native strives to cover a broad range of use cases, it’s essential to remember that it is not a silver bullet for every scenario. Understanding when to rely on pure React Native components and when to delve into native modules or custom native UI components is key. This balance allows you to deliver smooth, performant applications that leverage the unique strengths of each platform without sacrificing development speed.

Embracing the Hybrid Nature of React Native

React Native lives at the intersection of native and JavaScript worlds. This hybrid nature brings enormous power but also complexity. On one hand, you write declarative UI code in JavaScript and React. On the other hand, you sometimes need to communicate with native platform APIs or third-party SDKs via the native bridge.

This hybrid approach encourages developers to deepen their knowledge not only of React and JavaScript but also of native iOS and Android development paradigms. Gaining familiarity with Objective-C/Swift and Java/Kotlin can be invaluable when implementing custom native modules or debugging platform-specific issues.

The ecosystem also provides a vast number of community-built native modules that help bridge gaps, but it’s essential to evaluate their quality and maintenance before integrating them. Sometimes rolling your native module is the best option for control, performance, and reliability.

Prioritizing Performance and User Experience

Mobile users expect apps to be fast, responsive, and visually appealing. React Native provides numerous tools to help you optimize performance:

  • Use React. memo and PureComponent to avoid unnecessary re-renders. 
  • Leverage FlatList and SectionList for efficiently rendering large lists. 
  • Offload animations to the native UI thread using Reanimated 2 and Gesture Handler. 
  • Profile and monitor performance regularly using tools like Flipper, Instruments (iOS), and Systrace (Android). 

Delivering a seamless user experience also means handling network unreliability gracefully with offline support and providing smooth navigation transitions. As apps grow, adopting code-splitting and lazy loading strategies can reduce startup time and keep your app feeling snappy.

The Importance of Robust Debugging and Testing

Debugging in React Native requires mastering multiple tools and environments. From JavaScript debugging via Chrome DevTools to native debugging using Xcode and Android Studio, proficiency across these areas helps diagnose problems efficiently.

The React Native ecosystem continues to evolve its debugging tools. For example, Flipper has become a powerful multi-platform debugger integrating React DevTools, network inspection, and performance monitoring in one place.

Beyond debugging, rigorous testing is vital to maintain app stability. Write unit tests for your JavaScript logic, snapshot tests for UI components, and end-to-end tests using tools like Detox. Continuous integration pipelines that automatically run tests on every commit can catch regressions early and streamline collaboration.

Best Practices for Scalable React Native Projects

As your app grows, so does the complexity of managing codebases, dependencies, and builds. Adopting a well-thought-out project structure helps keep your codebase maintainable and scalable. Feature-based folder organization groups related files together, making it easier to onboard new team members and manage changes.

Incorporating TypeScript is highly recommended for larger projects. TypeScript’s static type system catches errors at compile time and improves code readability and editor tooling. It integrates well with React Native and many community libraries, providing a more robust development experience.

Additionally, following consistent coding standards and using linting and formatting tools like ESLint and Prettier helps maintain code quality across teams.

Security: A Non-Negotiable Aspect

Mobile applications often handle sensitive user data, making security paramount. React Native developers must be vigilant about:

  • Securing network communications with HTTPS and certificate pinning. 
  • Using encrypted storage solutions for sensitive data rather than plain AsyncStorage. 
  • Implementing robust authentication flows, including biometrics if possible. 
  • Avoidingthe  exposure of API keys and secrets in the codebase. 
  • Keeping dependencies up to date to patch vulnerabilities. 

Security should be baked into the development process from day one rather than being an afterthought, especially when deploying to production environments.

The Growing Ecosystem and Community Support

React Native benefits from a vibrant and rapidly growing community. Thousands of open-source libraries and tools extend the framework’s capabilities—from navigation and state management to advanced animations and native hardware integration.

Community forums, GitHub repositories, and platforms like Stack Overflow provide rich resources for learning and troubleshooting. Staying engaged with the community through conferences, meetups, and online discussions can accelerate your growth and keep you informed about best practices and emerging trends.

Continuous Learning and Staying Up-to-Date

React Native and its ecosystem evolve rapidly, with frequent releases introducing new features, performance improvements, and breaking changes. To keep your skills sharp:

  • Follow the official React Native blog and release notes. 
  • Monitor popular repositories for updates. 
  • Experiment with new APIs in side projects. 
  • Read blog posts and watch tutorials from thought leaders. 
  • Engage in open-source contributions. 

By embracing lifelong learning, you can adapt quickly to changes and leverage new capabilities to build better apps.

Final Words: The Future of React Native

React Native has come a long way since its inception and shows no signs of slowing down. Its model of “learn once, write anywhere” aligns well with the needs of modern app development teams that demand agility and efficiency.

New initiatives like React Native’s Fabric architecture and TurboModules promise to further improve performance and modularity by reducing bridge overhead and enabling synchronous native module calls.

Additionally, React Native’s integration with the broader React ecosystem, including React Hooks and Concurrent Mode, will unlock even more powerful patterns for building responsive, concurrent user interfaces.

As mobile and web convergence continues, projects like React Native for Web enable you to reuse React Native components on the web, creating truly universal apps.
