Welcome to your comprehensive React Hooks learning resource! This guide covers all React hooks from basic to advanced, with practical examples and interview-ready explanations.
Local component state management, functional updates, lazy initialization, and batching.
Side effects, cleanup functions, dependency arrays, and common pitfalls to avoid.
Synchronous effects after DOM mutations, layout measurements before paint.
DOM references, mutable values, instance variables without triggering re-renders.
Share values across components without prop drilling, context optimization patterns.
Complex state management with pure reducers, actions, and immutable updates.
Memoize expensive computations, referential equality, and optimization strategies.
Stable function references, React.memo optimization, dependency management.
Generate stable, unique IDs for accessibility and SSR-safe applications.
Expose imperative APIs through refs, controlled component interfaces.
Mark updates as non-urgent, improve user experience with concurrent rendering.
Defer expensive updates, lag behind fast-changing values for smooth UX.
Wire form actions into component state, handle pending states and errors.
Access form submission status, create loading states and submission feedback.
Optimistic UI updates, rollback on failure, improved perceived performance.
Build reusable logic: useLocalStorage, useFetch, useDebounce, and more patterns.
Master useState and useEffect before moving to advanced hooks. They form the foundation for everything else.
Each hook page includes runnable examples. Import them into your development environment and experiment.
Understanding the "why" behind each hook is more valuable than memorizing syntax. Focus on the concepts.
💡 Pro Tip: Use this guide as a reference during development. Each hook page is designed for quick lookup and includes common patterns you'll encounter in real projects.
