231,271 PointsAt about 2:48 in the video, the instructor says "Since fetch is only concerned with sending a request and receiving a response from the server, we should also provide a way of checking for and handling failed HTTP responses."
What he means is that while the catch method responds to errors related to getting any kind of server response, it does not react to a response that is successfully received, but it contains a code indicating that the server encountered a problem while processing the request.
Similar to how the first type of error was demonstrated by misspelling the "api" part of the request URL, you can demonstrate this other kind of error by misspelling the "random" part of the URL.
