Will `fetch` reject the promise on a 404 response?

✓Correct answer: No: you have to check the status yourself via res.ok
2Yes: any 4xx or 5xx status rejects the promise with an error object
3Yes, but only for 5xx; 4xx responses are considered successful

Explanation

An HTTP error response is still a response. You need an explicit check: if (!res.ok) throw new Error(res.status). The promise rejects on network failure, CORS blocking or cancellation via AbortController.
