Creating the handleError function

You should have noticed that the login() and register() functions have a catchError function that points to another function called the handleError. At this moment in time, we are going to create this function, which is in charge of showing the possible errors that our request may have.

Add the following code right after the getUser() function:

private  handleError(error:  HttpErrorResponse) {
        if (error.error  instanceof  ErrorEvent) {
                // A client-side error.
                console.error('An error occurred:',                error.error.message);
        } else {
                // The backend error.
                return  throwError(error);
        }
        // return a custom error message
        return  throwError('Ohps something wrong happen here; please try again later.');
}

We are logging the error ...
