It improves performance by only rendering visible items instead of the entire list.\n\n---\n\n## 📌 Features\n\n- ⚡ High-performance list rendering with virtualization\n- 📏 Auto responsive sizing using `AutoSizer`\n- 🧠 Efficient rendering using `List` component\n- 📝 Dynamic content generation using `lorem-ipsum`\n- 🖼️ Image + text list items\n- 🔄 Smooth scrolling with overscan optimization\n\n---\n\n## 🛠️ Tech Stack\n\n- React\n- react-virtualized\n- lorem-ipsum\n- CSS\n\n---\n\n## 📂 Project Structure\n\nsrc/ │ ├── components/ │ └── ListItem.jsx │ ├── App.js ├── App.css └── index.js\n\n```bash\n\n---\n\n## 📦 Installation\n\n# Clone the repository\ngit clone https://github.com/DeveloperMonirBD/react-virtualized-list.git\n\n# Navigate into the project\ncd react-virtualized-list\n\n# Install dependencies\nnpm install\n\n```\n\n## ▶️ Run the App\n\n```Bash\nnpm start\n```\n\nApp will run at:\n\n```\nhttp://localhost:5173\n```\n\n## 🧠 How It Works\n\n- `react-virtualized` renders only the visible rows in the viewport.\n- `AutoSizer` automatically adjusts width and height based on the container.\n- `List` component handles rendering large datasets efficiently.\n\n## 📌 Key Code Example\n\n```JavaScript\n\n\u003cAutoSizer\u003e\n  {({ width, height }) =\u003e (\n    \u003cList\n      width={width}\n      height={height}\n      rowHeight={50}\n      rowCount={5000}\n      rowRenderer={renderRow}\n      overscanRowCount={5}\n    /\u003e\n  )}\n\u003c/AutoSizer\u003e\n\n```\n\n## ⚠️ Performance Tips\n\n- Use `useMemo` to avoid recreating large datasets on every render.\n- Use `React.memo` for list items to prevent unnecessary re-renders.\n- Keep row height fixed for better performance.\n\n## 🧩 Dependencies\n\n```Bash\nnpm install react-virtualized lorem-ipsum\n```\n\n## 📸 Demo Data\n\n- 👤 Name\n- 🖼️ Image (placeholder)\n- 📝 Random sentence (generated via lorem-ipsum)\n\n## 📈 Use Cases\n\n- Chat applications\n- Infinite scrolling feeds\n- Large data tables\n- Logs viewer\n- Social media feeds\n\n## 🤝 Contributing\n\nContributions are welcome!
