This example renders a minimal React page that loads the React production library from a CDN and logs the React object to the browser console. The page displays no visual output, only an empty HTML body with a script that calls `console.log(React)`. It serves as a bare-bones demonstration of including React via a script tag without any additional setup or rendering logic. The accompanying `index.js` file contains only a placeholder `console.log('Hello world')` statement, showing the simplest possible JavaScript integration.
