What are Custom Hooks?

Accepted Answer

Custom Hooks are reusable functions in React that allow you to extract logic from components.

Custom Hooks are functions that start with the word 'use' and can call other Hooks if needed.
They are used to share stateful logic between components without using higher-order components or render props.
Custom Hooks can be used to handle common tasks like fetching data, managing form state, or subscribing to events.
They promote code reusability and make it easier to separate concerns in your React components.

Accepted Answer

A Custom Hook is a function in Javascript whose name begins with ‘use’ and which calls other hooks. It is a part of React v16.8 hook update and permits you for reusing the stateful logic without any need for component hierarchy restructuring.
In almost all of the cases, custom hooks are considered to be sufficient for replacing render props and HoCs (Higher-Order components) and reducing the amount of nesting required. Custom Hooks will allow you for avoiding multiple layers of abstraction or wrapper hell that might come along with Render Props and HoCs.
The disadvantage of Custom Hooks is it cannot be used inside of the classes.
