# responseType property

String responseType
read / write

String telling the server the desired response format.

Default is `String`. Other options are one of 'arraybuffer', 'blob', 'document', 'json', 'text'. Some newer browsers will throw NS_ERROR_DOM_INVALID_ACCESS_ERR if `responseType` is set while performing a synchronous request.
