React JS Hooks
React JS Hooks are functions that let you use state and other React features in functional components. They were introduced in React 16.8 to provide a more straightforward and cleaner way to handle stateful logic in functional components, which were previously stateless. Key React Hooks include:
useState: Allows functional components to manage local state.
useEffect: Performs side effects in functional components, such as fetching data or updating the DOM.
useContext: Provides a way to consume a context (global state) within a functional component.
useReducer: An alternative to
useState
for managing more complex state logic.useRef: Allows functional components to access the DOM nodes or store mutable values persistently.
React Hooks streamline component logic, making functional components as powerful as class components while promoting code reusability and readability.
