Summary of ReactJS Architecture
| Feature | Description |
|---|---|
| Component-Based | Modular, reusable UI blocks. |
| JSX | Simplifies UI development with HTML-like syntax in JavaScript. |
| Virtual DOM | Efficient DOM updates for performance. |
| State and Props | Manage dynamic data and communication between components. |
| Hooks | Simplifies state and lifecycle management in functional components. |
| Unidirectional Data Flow | Predictable and easier-to-debug data management. |
| Extensible Architecture | Compatible with libraries for routing, state management, and UI components. |
React’s architecture enables developers to build dynamic, high-performance, and maintainable user interfaces with ease.
