5,877 PointsQuestion with else statement for error message in this video
Here's the code from the video...
else {
const message = there was an error getting the profile for ${username} (${response.statusCode})
;
const statusCodeError = new Error(message);
printError(message);
}
I don't understand why we are creating the statusCodeError variable, could someone please explain why this is required? And if it is required?
Thanks!

But first, you have an error in your code. The last line is to print the error string, and should be:
printError(statusCodeError);
So now with that fixed, when an error occurs in getting the profile, the statusCodeError which was filled in with a message explaining what went wrong will appear on the screen. Without all this, if a problem occurred, you would just not see anything at all.

The reason we make an error variable is to utilize the printError function. Remember the printError function needs the parameter passed in to be an error since it calls error.message. We could simply print the string to display the error but using the printError function brings neatness and consistency to our code since we already used it to print all of our other errors.
