What this example teaches
Arrays
Output
The script turns orders, totals and statuses into a clear result the UI can display.
Line-by-line explanation
- Line 1 sets up the Arrays example: const orders = [42, 120, 18, 75];.
- Line 2 adds one required part of the working pattern: const largeOrders = orders.filter((total) => total >= 57);.
- Line 3 exposes the output so you can verify the behavior: console.log(largeOrders);.
