Higher-Order Components (HOCs) are a design pattern in React that allows you to reuse component logic and behavior. They are not a part of the React API but rather a pattern built on the principles of component composition and function chaining. HOCs take a component as input and return a new component with additional functionality or props.
Example Code:
Let's create a simple HOC that adds a "click count" feature to a component.
In this code:
This demonstrates how HOCs can be used to add or modify functionality in a reusable and composable manner in React.
Effective Use of HOCs:
While HOCs are a powerful pattern, it's important to use them judiciously, as overuse can lead to complex component hierarchies. Additionally, consider other patterns like Render Props or Hooks, which offer alternatives to achieving similar functionality in a more idiomatic way in modern React applications.
