This example displays a report of cars priced under $2000, listing them by year, make, model, and price. It also shows a "Loading ..." message before the data appears. The code uses JavaScript objects, arrays, and modules, employing `Promise`, `setTimeout`, and `JSON.parse` to simulate an asynchronous data fetch. The report is generated via the `generateReport` function, which filters and maps car data, and is then displayed in a `<pre>` element.
