Passing props in Class Components
When working with React components, understanding props is essential. Props allow data to flow from parent components to child components, enabling dynamic content and efficient communication within your application. Whether you’re dealing with class components or functional components, the principles remain consistent.
Example: Program to demonstrate the use of props in class components.
// Filename - App.js
import React from "react";
class App extends React.Component {
render() {
return <h1>{this.props.data}</h1>;
}
}
class propsExample extends React.Component {
constructor(props) {
super(props);
this.state = { change: true };
}
render() {
return (
<div>
<button
onClick={() => {
this.setState({ change: !this.state.change });
}}
>
Click Here!
</button>
{this.state.change ? (
<App data="Welcome to w3wiki" />
) : (
<App data="A Computer Science Portal for Geeks" />
)}
</div>
);
}
}
export default App;

React Class Components
Class Components are the reusable code blocks or classes that extends the React.Component. React class components are the backbone of most modern web applications built using React JS. In this article, we’ll learn what class components are, their advantages, how to manage the state and events of the application and how to use them effectively.
