React Hooks

Hooks are functions that let you “hook into” react state and lifecycle features from function components. They were introduced in React 16.8.

Basic Hooks

• useState: Lets you add state to a functional component.
• useEffect: Lets you perform side effects in functional components. This can be for data fetching, subscriptions, or manually changing the DOM.
• useContext: Accepts a context object and returns the current context value.

Additional Hooks

• useReducer: An alternative to useState. Often preferred for complex state logic.
• useCallback: Returns a memoized callback.
• useMemo: Returns a memoized value.

Hooks allow you to reuse stateful logic without changing your component hierarchy, which is a major advantage over class components.
