| Aspect | Composition | Inheritance |
|---|---|---|
| Primary Use Case | Building reusable UI components and managing code complexity | Extending base classes with additional functionality (less common in React) |
| Flexibility | High - Easily mix and match components | Lower - Hierarchical and rigid structure |
| State and Props | State and props are passed explicitly to child components | State and methods are inherited |
| Code Reuse | Promotes code reuse by composing multiple components | Promotes code reuse by inheriting properties and methods |
| Examples | Wrapping components, Higher Order Components (HOCs), Render Props, Hooks | Extending a class-based component |
| Component Updates | Easier to manage and understand updates and side effects | Can be harder to track state and prop changes through inheritance |
| Testing | Easier to test individual components | Testing can be more complex due to tightly coupled functionality |
| Error Handling | Easier to handle errors in isolated components | Errors can propagate through the inheritance chain, making debugging more difficult |
