How to print Hello World in React JS in Detail
To print "Hello" in a React component, you can follow these steps:
1. Create a new React component: First, create a new React component by extending the React.Component class. You can name the component anything you like, but for this example, let's call it Hello.
import React from 'react';
class Hello extends React.Component {
render() {
return (
<div>
{/* code to print "Hello World" will go here */}
</div>
);
}
}
2. Add JSX to the render method: In the render method of your Hello component, add JSX that will output the text "Hello". To do this, you can use the <p> element to wrap the text and then include the text "Hello" within it.
import React from 'react';
class Hello extends React.Component {
render() {
return (
<div>
<p>Hello World</p>
</div>
);
}
}3. Render the Hello component: Finally, you can render the Hello component by importing it into another component and including it in that component's JSX. For example, you could render the Hello component in the App component like this:
import React from 'react';
import Hello from './Hello';
class App extends React.Component {
render() {
return (
<div>
<Hello />
</div>
);
}
}
When you run your React application, you should see the text "Hello World" displayed on the page.
