React Hooks
React Hooks are functions introduced in React 16.8 that allow developers to use state and other React features in functional components, eliminating the need for class components. They provide a way to reuse stateful logic across components without changing component hierarchy, making code more readable and maintainable. Common hooks include useState for state management, useEffect for side effects, and useContext for accessing context.
Developers should learn React Hooks to write cleaner, more concise React applications, as they simplify component logic and reduce boilerplate code compared to class components. They are essential for modern React development, enabling features like custom hooks for reusable logic and improving performance with hooks like useMemo and useCallback. Use cases include building interactive UIs, managing form state, handling API calls, and integrating with global state management.
