         <p>An alternative construct to the complete callback option, the <code>.always()</code> method replaces the deprecated <code>.complete()</code> method.</p>
         <p>In response to a successful request, the function's arguments are the same as those of <code>.done()</code>: data, textStatus, and the jqXHR object. For failed requests the arguments are the same as those of <code>.fail()</code>: the jqXHR object, textStatus, and errorThrown. Refer to <code><a href="/deferred.always/">deferred.always()</a></code> for implementation details.</p>
