The Cars Report example demonstrates how to fetch, filter, and format car data asynchronously using JavaScript promises and ES6 modules. It shows a loading state followed by a text report listing cars with prices under a specified threshold. The code uses the native `Promise` API via `getCars`, `Array.prototype.filter` and `.map` in `generateReport`, and template literals in `formatCar` to construct the output. The HTML page displays the result in a `<pre>` element, with the source data embedded as a JSON string.
