React Native Documentation

React Native is a popular JavaScript framework for building native mobile applications using React. This documentation provides a comprehensive guide to help you get started with React Native development.

Getting Started

Before you begin, make sure you have the following prerequisites:

Node.js and npm installed
React and React Native installed globally
A mobile device or emulator for testing

To get started, follow these steps:

Create a new React Native project using the React Native CLI:
```
npx react-native init MyNewProject
```
Navigate to your project directory:
```
cd MyNewProject
```
Start the development server:
```
npx react-native start
```

Run your app on a device or emulator:

npx react-native run-android
# or
npx react-native run-ios

Key Concepts

Here are some key concepts in React Native:

Components: Building blocks of your app, similar to React components.
State: Data that changes over time and is used to update the UI.
Props: Data passed to components to configure their behavior.
Styles: CSS-like styles for styling your components.
Navigation: Managing navigation between different screens in your app.

Sample Code

Here's a simple example of a React Native component:

import React from 'react';
import { View, Text, StyleSheet } from 'react-native';

const App = () => {
  return (
    <View style={styles.container}>
      <Text style={styles.title}>Hello, React Native!</Text>
    </View>
  );
};

const styles = StyleSheet.create({
  container: {
    flex: 1,
    justifyContent: 'center',
    alignItems: 'center',
    backgroundColor: '#F5FCFF',
  },
  title: {
    fontSize: 20,
    textAlign: 'center',
    margin: 10,
  },
});

export default App;
