They are not a new type of component but rather a function that takes a component and returns a new component with additional functionality. HOCs enable you to add behavior to components without modifying their underlying structure or code.

In this blog, we will explore what HOCs are, how they work, and some practical use cases for applying this pattern in your React applications.

Syntax of an HOC:

const EnhancedComponent = higherOrderComponent(WrappedComponent);

Where:
