Question

A browser fetch request completes normally at the network level, but the server returns HTTP 404. Which statement correctly explains how a UI should detect this error? Select one answer.

Accepted Answer

`fetch()` fulfills with a Response; check `response.ok` or `response.status` before treating it as success.

Answer

An HTTP error can only be detected by checking `navigator.onLine`.

Answer

The response is automatically converted into an Error object when `response.json()` is called.

Answer

`fetch()` always rejects its promise for HTTP 404, so checking the status is unnecessary.
