What is textStatus when an HTTP error is received from an AJAX request?

Question

In jQuery, when an AJAX request fails due to an HTTP error (e.g., 500 Internal Server Error) what is the value of the textStatus argument to the error handler? E.g.,

$.ajax(...).fail(function(jqXHR, textStatus, errorThrown) {
    console.log(textStatus); // What is this when an HTTP error occurs?
});

The jQuery documentation for $.ajax() simply lists the possible values, but there is no clear explanation as to when they occur. Particularly, jQuery mentions:

When an HTTP error occurs, errorThrown receives the textual portion of the HTTP status, such as "Not Found" or "Internal Server Error."

But it does not say what the value of textStatus will be.

@RoryMcCrossan If there was an `httperror` status, I'd agree. — Uyghur Lives Matter, Jan 24 '18 at 16:28
If you mean that you want to get the HTTP status code from the response, you can do that: https://stackoverflow.com/questions/5344145/how-to-get-response-status-code-from-jquery-ajax — Rory McCrossan, Jan 24 '18 at 16:30
@RoryMcCrossan I don't particularly care about the exact HTTP status code, just whether the response is specifically an HTTP response error (e.g., 4xx or 5xx) as oppose to some other potential error (e.g., transport, timeout, etc.). — Uyghur Lives Matter, Jan 24 '18 at 16:33

When you receive an HTTP error response (e.g., 500 Internal Server Error), the value of the textStatus argument will be "error". This was determined through testing.
