React JS Example: Simple Greeting Component

Here's an example of a simple React component that displays a greeting message:

import React from 'react';

class Greeting extends React.Component {
  render() {
    return (
      <div>
        <h1>Hello, ' + this.props.name + '!</h1>
        <p>Welcome to my website.</p>
      </div>
    );
  }
}

export default Greeting;

In this component, we define a 'Greeting' class that extends the 'React.Component' class. The 'render()' method returns a JSX element that displays a greeting message, using the 'name' prop passed to the component. We export the 'Greeting' component as the default export, so that it can be imported and used in other parts of our application.
