why did he not also use request.on("end", ... ) to get the url query string?

In the Node.js Basic course, he explained that the 'data' event gives data in parts which is why we also need the 'end' event to get the complete data. I am guessing the reason why he is not using it is because the query string is so short that the data is send in one go? Or perhaps the response.end() is the same as the 'end' event? Or maybe it is something else?

This implementation relies on the data being complete in one package, which is adequate for the particular info being requested.. A more generic and robust implementation would just collect on "data" events, and respond on the "end" event as you saw in the previous example.

The call to "response.end()" completes and sends the outgoing message and is not related to the "end" event of the incoming one.
