javascript - I have some doubts regarding the fetch api in case of errors

Question

I have been experimenting with the fetch api, and it's still not clear when it is rejected. For example when I try the following: fetch("https://stackoverflow.com/") it is rejected whereas if i insert a completely random text like "aoishoaisoab" it is resolved eventhough such URL doesnt exists. I have read that it is only rejected if there is a network error. Then how come it is rejected?

Be sure that you are not making this request from your browser, you will get a CORS error since the fetched page is not hosted on the same domain as the JS Code.

For testing purposes you can use a CORS plugin that allows requests like that.
