Function Components vs Class Components

Function Components vs Class Components

1. 1Function components use simple JavaScript functions to create component.
2. 2Class components use ES6 class syntax that extends React.Component class
3. 3Function components return UI directly using JSX
4. 4Class components return UI using render() method
5. 5Function components use Hooks like useState, useEffect to manage state and side effects
6. 6Class components use this.state and lifecycle methods like componentDidMount, componentDidUpdate, and componentWillUnmount
7. 7Function components do not use the "this" keyword
8. 8Class components use "this" to access props and state
9. 9Function components are cleaner, shorter, and easier to test
10. 10Class components are more verbose and harder to reuse
11. 11Hooks work only in function components, not in class components
12. 12Function components support custom hooks for logic reuse
13. 13Class components require higher-order components (HOC) or render props for logic reuse
14. 14Function components can use useContext, useReducer, and other advanced hooks
15. 15Class components are less commonly used in modern React apps
16. 16Function components are used in modern React (React 16.8 and above)
17. 17Class components were the standard before React introduced Hooks
