Output
The script turns orders, totals and statuses into a clear result the UI can display.

- Line 1 sets up the Functions example: const lesson = "Functions";.
- Line 2 adds one required part of the working pattern: const checklist = ["understand", "run", "change", "explain"];.
- Line 3 exposes the output so you can verify the behavior: console.log(lesson + ": " + checklist.join(" -> "));.
