What this example teaches
Fetch API
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 Fetch API example: async function loadOrders() {.
- Line 2 adds one required part of the working pattern: const response = await fetch("/api/orders");.
- Line 3 adds the decision or filter that controls the result: if (!response.ok) throw new Error("Could not load orders");.
- Line 4 exposes the output so you can verify the behavior: return response.json();.
- Line 5 adds one required part of the working pattern: }.
Why this example is useful
