Full Definition

Hooks (introduced in React 16.8) let functional components use state (useState), run side effects (useEffect), access context (useContext), and more. Before hooks, only class components could have state. Key hooks: useState, useEffect, useContext, useMemo, useCallback, useRef. Custom hooks let you extract reusable stateful logic.

Knowledge Graph

Avoid these mistakes when using React Hooks:

1

Calling hooks inside conditions or loops → Hooks must always be called at the top level of a React function — same order, every render.

2

Forgetting dependencies in useEffect → Include all variables the effect depends on in the dependency array, or use eslint-plugin-react-hooks to catch this.
