What are Custom Hooks in React?

Custom Hooks are reusable JavaScript functions that contain React Hook logic. They allow developers to extract common functionality from components and reuse it across multiple parts of an application. A custom hook must start with the word 'use', such as useFetch or useAuth. This improves code organization, maintainability, and reusability.
