Question 1
What would happen if we skipped the following line of code in the ‘responseError’ function of the interceptor?
return $q.reject(response);It’s just a precaution. It’s not really needed here.
The call will still return to the caller and it will look like our promise ‘resolved’ when it fact, the promise failed. The caller code will treat the response object as if it’s the expected result which will probably cause errors.
Everything will resolve successfully.
The HTTP call will fail and throw errors.
