Hooks are a new feature in React that allow you to add state and other React features to functional components. Prior to Hooks, the only way to add state and other React features to a component was by using class components, but with Hooks, it's possible to do so in functional components as well.
Some common Hooks include:
useState: This Hook allows you to add state to your functional component. It takes an initial state as its argument and returns an array with two elements: the current state and a function that can be used to update the state.
useEffect: This Hook lets you perform side-effects in functional components. It takes a callback function as its argument and runs it after every render.
useContext: This Hook lets you access the context object
useReducer: This Hook is similar to useState, but it allows you to manage complex state transitions and actions.
Hooks make it easier to reuse state logic and side-effects across multiple components and make your code more maintainable, testable and readable. By using Hooks, you can write functional components that have the same capabilities as class components, but with a simpler syntax.
It's important to note that Hooks are a React-specific feature, and are not part of the JavaScript language itself.
