In the previous blog post, we learned how to render a simple component in React using JSX. In this blog post, we will learn how to pass data to a component using props and display it in the component.

Step 1: Create a new file

Create a new file called Person.js in the src folder of your React project.

Step 2: Write the component code

In the Person.js file, write the following code:

import React from 'react';

const Person = (props) => {
  return (
    <div>
      <h1>{props.name}</h1>
      <p>{props.age} years old</p>
    </div>
  );
}

export default Person;

Here, we have created a functional component called Person which accepts props as an argument. Inside the component, we have used the props object to display the name and age of the person.

Step 3: Render the component

In the App.js file, modify the code as follows:

import React from 'react';
import Person from './Person';

function App() {
  return (
    <div>
      <h1>My React App</h1>
      <Person name="John Doe" age="25" />
    </div>
  );
}

export default App;

Here, we have imported the Person component and used it inside the App component by passing name and age as props.

Step 4: Run the application

Save the files and start the React application using the following command in the terminal:

npm start

Visit localhost:3000 in your browser to see the output.

In the browser, you should see the following:

Congratulations! You have successfully passed data to a component using props and displayed it in the component.
