using the .end() method

why didn't we have to use the .end() method when putting together our other requests to the different routes? We used .json() as the last method in some of the other routes, does this also end the request?

Hi Nicholas Lansing,

You are correct in that using... 

res.json(/* some data goes here */)

...to send back data essentially ends a response. I say essentially, because other information can be chained to a res.json() statement (like a status code).

An example of a reason you might use res.end() is if a request has been made to delete a resource. In this case, there would be nothing to send back to the client (as the resource has been deleted), so you would just end the response with res.end().

Hope that helps. And really good question.

Thanks a lot for the response, Brandon! All clear now, that makes sense.
