What is the purpose of hooks in React?

Hooks in React provide a way to add state and other React features in functional components. They allow you to use state and other React features without having to write a class.

Hooks make it easier to manage and update state in functional components, simplifying the process of writing components. They provide commonly used hooks functions such as useState, useEffect, useContext, and more.

1. useState is used to add and manage state in functional components. It returns a state value and a function to update the state, which can be accessed using array destructuring.
2. useEffect is used to perform side effects after each render, such as subscribing to data or updating the DOM. It takes a callback function and executes it after the component renders.
3. useContext is utilized to access and use React Context in functional components. It takes in a Context object and returns the value of the current context.
4. Other commonly used Hooks also include useReducer, useCallback, useMemo, etc., which can help you better manage the state and logic of components.

Using hooks can make code cleaner, more readable, and improve the testability and reusability of components. At the same time, hooks can also help you better understand and grasp the basic concepts and principles of React.
