Understanding Custom Hooks in React
Introduction
React hooks, introduced in version 16.8, revolutionized the way developers write functional components by allowing state and side effects to be managed without the need for class components. While React provides built-in hooks like useState, useEffect, and useContext, developers can also create their custom hooks. These custom hooks enable you to extract and reuse logic across components, making your code more modular, readable, and maintainable.
In this blog, we’ll explore what custom hooks are, how they work, and how to create and use them effectively in your React applications.
What are Custom Hooks?
A custom hook is a JavaScript function whose name starts with the word “use” and can call other hooks inside it. It allows you to encapsulate logic that can be shared across multiple components. Custom hooks don’t return JSX; instead, they return a value or a set of values (such as state or functions) that can be used by the components that call them.
Custom hooks are a powerful way to abstract complex logic, enhance code reusability, and improve the readability of your codebase.
