Cars Report
This example shows a loading state followed by a text-based report of cars priced under $2,000, formatted as lines like “2009 Ford F150: $1950”. It uses asynchronous JavaScript with a `Promise` and `setTimeout` to simulate fetching car data from a JSON string, then filters and maps the array with `Array.filter`, `Array.map`, and `Array.join`. The code imports and exports functions via ES modules, and updates the DOM by setting the `textContent` of a `<pre>` element. The report is generated entirely in the browser without any external visualization library.
