Learn how Hooks let you manage state, side effects, context, refs, and more directly in functional components—without needing class components legacy.reactjs.org GeeksforGeeks . Core Built‑in Hooks: useState – Introduce state in function components and update it easily FreeCodeCamp legacy.reactjs.org . useEffect – Handle side effects like fetching data, subscriptions, timers, and cleanup FreeCodeCamp Built In . useContext – Access context values directly, bypassing tedious prop drilling FreeCodeCamp GeeksforGeeks . useReducer – Manage complex state logic using reducer patterns, similar to mini-Redux inside a component FreeCodeCamp GeeksforGeeks . useRef – Access DOM elements or store persistent values without causing re-renders FreeCodeCamp GeeksforGeeks . useCallback – Memoize functions to avoid unnecessary re-creation on renders FreeCodeCamp blog.openreplay.com . useMemo – Cache expensive calculation results to improve performance FreeCodeCamp blog.openreplay.com . Advanced Hooks You Should Know: useLayoutEffect – Like useEffect, but runs synchronously after DOM updates—great for measuring layout or performing animations Built In GeeksforGeeks . useImperativeHandle – Customize values exposed by refs in parent components GeeksforGeeks . useDebugValue, useDeferredValue, useTransition, useId, useSyncExternalStore, useInsertionEffect – Useful in specialized scenarios for debugging, deferred rendering, concurrent UI updates, ID generation, and integration with external stores or CSS insertion legacy.reactjs.org GeeksforGeeks Built In . Rules & Best Practices: Only call Hooks at the top level of React function components or custom Hooks—no loops, conditions, or nested functions legacy.reactjs.org uxpin.com . Hooks must be used in React functional components or custom Hooks—not in plain JavaScript functions legacy.reactjs.org uxpin.com . Leverage useCallback and useMemo smartly to optimize performance; avoid stale closures and unnecessary recomputations uxpin.com Medium . Custom Hooks: Learn how to extract reusable, stateful logic into your own Hooks. Follow naming conventions (useSomething) for consistency and tooling compatibility legacy.reactjs.org GeeksforGeeks . See real-world examples like useWidth or data-fetching Hooks for practical reusability GeeksforGeeks Built In . Why Watch This Video?
