Accepted Answer

In React, hooks are functions that allow you to use state and other React features in functional components, which were previously only available in class components. Hooks provide a way to manage state and perform side effects in functional components without the need for classes.

Here are some commonly used hooks in React:

useState: This hook allows you to add state to functional components. It returns a stateful value and a function to update that value.
useEffect: This hook enables you to perform side effects in functional components. It runs after every render and can be used to handle things like data fetching, subscriptions, or manually changing the DOM.
useContext: This hook allows you to access the value of a context in a functional component. It retrieves the current value of the context provided by a parent component using the Context API.
