I moved this check to the createResponse() function so it always produces the correct response no matter what XHR instance it's given. This logic belongs here.

@avivasyuta, also note that representing the status codes that must not have a body in an array is more practical in this case than an object. At its core, we want a list of things, so an array is the right choice here!

Yes, at first I thought that it would be more productive to use an object, but for three elements this can be neglected.

Take a look, I've expanded the tests, creating three separate test cases instead of iterating over the list of status codes. It's crucial to keep the tests as flat and straightforward as possible. This means as little logic specific to tests as possible, like test.each(). This results in tests that are easy to find, read, change, and remove.

I made this server route return whichever response status code that was requested by the client.

This is a great approach. I didn't think of it right away.

I liked how you orchestrated the test! This is but a small adjustment.
