What information is typically available within the error handler function?

The error handler function receives three arguments: `jqXHR` (the XMLHttpRequest object), `textStatus` (a string describing the type of error), and `errorThrown` (an error object, if one was thrown). `jqXHR` provides details about the request, `textStatus` gives a human-readable error message (e.g., 'timeout', 'error', 'abort'), and `errorThrown` contains the specific error details.
