Custom Hooks in React are JavaScript functions that allow developers to extract and reuse component logic. These hooks can leverage other React hooks, such as useState, useEffect, or useContext, to encapsulate specific functionalities and manage state.

Key characteristics of Custom Hooks:

1. Reusability- They enable sharing of stateful logic across multiple components without prop drilling or complex inheritance patterns.

2. Modularity- They help organize code into smaller, manageable modules, making components cleaner and easier to understand.

3. Naming convention- Custom hooks should start with use (e.g., useFetch, useCounter) to follow React's rules for hooks.

4. Encapsulation- They can encapsulate any kind of logic, such as API calls, form handling, state management, or even external libraries.

How to create a custom hooks-

Create a function: Define a JavaScript function that starts with use.

Use React hooks: Inside the function, use other React hooks or custom hooks to implement the desired functionality.
