This example displays the static text "hi" in a large HTML `<pre>` element. It imports a hard-coded JSON array of used cars—each with a year, make, model, and price—from `cars.js` using a JavaScript `export`, but that data is not rendered. The app runs in React with a standard `index.html` loading a `bundle.js` built by the framework; it relies solely on `document.getElementById` and `textContent` to update the message.
