# What is React Hooks?

Hooks are functions that let you “hook into” React state and lifecycle features from function components. Hooks don’t work inside classes — they let you use React without classes.

**Basic Hooks**
- useState
- useEffect
- useContext

**Additional Hooks**
- useReducer
- useCallback
- useMemo
- useRef
- useImperativeHandle
- useLayoutEffect
- useDebugValue
- useDeferredValue
- useTransition
- useId

**Library Hooks**
- useSyncExternalStore
- useInsertionEffect
