What's the purpose of sending a response when sending a post request?

I understand every bit of the request code here, but I'm not completely understanding the res.json() part. Is this just for verification on the client end that the request was properly received and stored?

Yes, it is for verification for the client that the request was properly received and stored. This response would then be used by an app to say "Comment Posted" or "Profile Image Created", etc, and then display it on the page as it appears on the server side.

I'd never really questioned it. On some operations, the returned value might differ from the posted one. For instance, the updated record could have an id or generated or transformed fields maybe.
