Integrating a New Frontend Framework

Provide an example of how to integrate a modern frontend framework like React, Vue, or Angular into an existing project to stay current with industry trends.

// Install React via npm
npm install react react-dom

This command installs React and ReactDOM, which are the essential packages for integrating React into a project.

import React from 'react';
import ReactDOM from 'react-dom';

// Create a simple React component
function App() {
  return (
    <div>
      <h1>Hello, World!</h1>
    </div>
  );
}

// Mount the React application to the existing DOM element
ReactDOM.render(
  <React.StrictMode>
    <App />
  </React.StrictMode>,
  document.getElementById('root')
);

This code imports React and ReactDOM, defines a simple React component called 'App', and then uses ReactDOM to render this component inside an existing DOM element with the ID of 'root'.

// Add a new div with id 'root' in your HTML file where you want the React app to hook into
<div id="root"></div>

This HTML div element acts as the mounting point for the React application. The 'root' ID is targeted by the 'ReactDOM.render' method to inject the React component.
