Introduction:
Higher-Order Components (HOCs) provide a powerful way to enhance and extend the functionality of React components. In this guide, we will explore advanced patterns and techniques for using Higher-Order Components with function components in React. From prop manipulation to composability, these patterns will empower you to create reusable and flexible components, promoting a modular and scalable architecture in your React applications.
