Creating Reusable React Components

The DRY Principle

"Don't Repeat Yourself" (DRY) is a fundamental principle of software development. In React, this means creating reusable components. A well-designed component can be used in multiple places throughout your application, saving you time and making your code easier to maintain.

Composition over Inheritance

React favors a compositional model. Instead of creating complex component hierarchies through inheritance, you should build complex UI by composing simpler components. The children prop is a powerful mechanism for this.

function Card({ children }) {
return

{children}

;
}

Props as an API

Think of your component's props as its public API. Design them to be clear, concise, and flexible. Use PropTypes or TypeScript to document and enforce the expected props, making your components easier for other developers (and your future self) to use.
