###**Introduction**
React Native is a popular open-source framework for building mobile applications using JavaScript and React. It was created by Facebook in 2015 and has gained a lot of popularity among developers due to its ease of use, flexibility, and performance. In this article, we will explore the reasons why React Native is a good choice for mobile app development, provide some small examples, and highlight the key differences between React Native, Flutter, and native mobile development.

####**Why React Native is a good choice ?!**🤔

**1. Cross-platform compatibility**
React Native allows developers to build applications that can run on both iOS and Android platforms, saving development time and costs. Instead of writing separate code for each platform, developers can use a single codebase for both platforms.

**2. Easy to learn and use**
Developers who are familiar with React will find it easy to learn and use React Native. The framework uses a similar syntax and structure to React, making it easy to get started with.

**3. Fast development**
React Native's hot reloading feature allows developers to see the changes they make in real-time, speeding up the development process. The framework also has a large number of pre-built components, allowing developers to quickly create complex UIs.

**4. Performance**
React Native uses a bridge to communicate between the JavaScript code and the native platform, allowing for smooth and fast performance. The framework also uses native components, ensuring that the app looks and feels like a native app.

####**Let's take a look at some small examples** ✅
#####Example 1: Creating a basic Hello World application
```
import React from 'react';
import { Text, View } from 'react-native';

const App = () => {
  return (
    <View>
      <Text>Hello World!</Text>
    </View>
  );
}

export default App;
```

#####Example 2: Creating a button that changes color when pressed
```
import React, { useState } from 'react';
import { View, Button } from 'react-native';

const App = () => {
  const [color, setColor] = useState('red');

  const changeColor = () => {
    setColor('blue');
  }

  return (
    <View>
      <Button title="Change color" onPress={changeColor} />
      <View style={{ backgroundColor: color, height: 100, marginTop: 20 }}></View>
    </View>
  );
}

export default App;
```

####**Key Differences between React Native, Flutter, and Native Mobile Development**

**1. Language**
React Native uses JavaScript, while Flutter uses Dart. Native mobile development uses platform-specific languages like Java or Kotlin for Android and Swift or Objective-C for iOS.

**2. Performance**
Flutter uses its own rendering engine, which allows for fast and smooth performance. React Native uses a bridge to communicate between the JavaScript code and the native platform, which can sometimes lead to performance issues. Native mobile development offers the best performance since it directly uses the platform-specific APIs.

**3. Tooling**
Flutter comes with a complete set of development tools, including an integrated
