 There are actually more events, the [modern specification](http://www.w3.org/TR/XMLHttpRequest/#events) lists them (in the lifecycle order):
 
 - `loadstart` -- the request has started.
-- `progress` -- a data packet of the response has arrived, the whole response body at the moment is in `responseText`.
+- `progress` -- a data packet of the response has arrived, the whole response body at the moment is in `response`.
 - `abort` -- the request was canceled by the call `xhr.abort()`.
 - `error` -- connection error has occurred, e.g. wrong domain name. Doesn't happen for HTTP-errors like 404.
 - `load` -- the request has finished successfully.
