This example demonstrates asynchronous data handling by displaying a filtered list of cars below a price threshold. A loading message appears first, then after a two-second delay, the report renders in large text. The code uses JavaScript Promises with `getCars` and `setTimeout` to simulate a delayed API response, while `generateReport` chains `filter`, `map`, and `join` operations to format car details from a hardcoded JSON array. The `formatCar` module constructs each line.
