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.
