## Introduction

### What is React Native?

React Native is an open-source framework developed by Facebook for building mobile applications using JavaScript and React. It allows developers to create native mobile apps for iOS and Android platforms using a single codebase. React Native uses native components, which makes the apps look and feel like native apps built using Swift or Java. It also provides a hot reloading feature, which allows developers to see the changes instantly without recompiling the entire app.

### Why is React Native popular among freelance developers?

React Native is popular among freelance developers for several reasons. Firstly, it allows developers to leverage their existing JavaScript skills to build mobile apps, eliminating the need to learn new programming languages. Secondly, it offers a fast development cycle, allowing developers to quickly iterate and deliver projects on time. Lastly, React Native has a strong community support with a vast number of open-source libraries and components, making it easier for freelance developers to find solutions to common problems and speed up development.

The E-commerce App project is aimed at building a mobile application for an online store. Users can browse through products, add them to the cart, and make purchases. The app also includes features like user authentication, product search, and order tracking.

### Features

- User authentication (login and registration)
- Product browsing and searching
- Product details with images, descriptions, and prices
- Add to cart and cart management
- Checkout and payment processing
- Order tracking and history

### Technologies Used

- React Native for building the UI components and managing the app's state
- Redux for state management
- React Navigation for handling navigation between screens
- Firebase for user authentication and backend services

#### Code Example

```javascript
// src/screens/ProductDetailsScreen.js

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

const ProductDetailsScreen = ({ route }) => {
  const { title, image, price } = route.params;

  return (
    <View>
      <Image source={image} />
      <Text>{title}</Text>
      <Text>{price}</Text>
      <Button title="Add to Cart" onPress={() => addToCart()} />
    </View>
  );
};

export default ProductDetailsScreen;
```

Explanation:

1. The `ProductDetailsScreen` component receives the `route` object as a prop from the navigation stack.

  };

  useEffect(() => {
    // Logic to fetch user's posts from the backend
  }, []);

  return (
    <View>
      <TextInput
        placeholder="What's on your mind?"
        value={postText}
        onChangeText={text => setPostText(text)}
      />
      <Button title="Post" onPress={() => handlePost()} />
    </View>
  );
};

export default PostScreen;
```

Explanation:
