React Starter
This example shows a minimal React application that renders a styled text message, “Hello React!”, centered on the page. It demonstrates the basic setup for using React with a browser-based build, where the UI is defined in JSX within a functional component. The app uses React 16.13.1 and ReactDOM to mount the component into a root `<div>` element from the HTML file. The rendering approach relies on `ReactDOM.render`, with the page’s styling applied via a CSS class defined in the `index.html` file.
