Built-in React hooks

The list of built-in React hooks.

React 16 introduced hooks, a new way of using stateful features in React components. React both has built-in hooks and provides a way to write custom hooks.

The following table summarizes the built-in React hooks:

Hook	Description
`useState`	Provides a way to store and update a stateful value. Updating the value triggers re-rendering.
`useEffect`	Used to perform side effects. By default, the effect runs after each render.
`useLayoutEffect`	Unlike `useEffect`, fires synchronously after DOM mutations while re-rendering.
`useContext`	Returns the current value of a React context.
`useReducer`	Similar to `useState`, but uses the same signature as Redux reducers.
`useMemo`	Returns a memoized value.
`useCallback`	Returns a memoized callback.
`useRef`	Used to store component instance variables.
`useImperativeHandle`	Used with `forwardRef` for exposing `ref` handlers to parent components.
`useDebugValue`	Used for development/debugging.
