An endpoint requires a JSON object with a string orderId. What must happen after JSON.parse succeeds?

1. Check that the result is a non-null, non-array object and that orderId is a string.
2. Nothing; valid JSON syntax guarantees the endpoint shape.
3. Call JSON.stringify on the parsed value and compare string lengths.
4. Check only that typeof result is object.
