fetch resolves even if 404?

Question

Using this code :

fetch(\'notExists\') // <---- notice 
    .then(
        function(response)
        {
           alert(response.status)
        }
    )         


        

Answer 1

Reject handler is for networking and CORS errors iirc. If the request reaches the server and it responds with a valid http response, the promise gets fulfilled, even if the response is of code 4xx or 5xx.
