Today, we look at a representative comment, sent to us by Nona. This particular comment was in a pile of code delivered by an offshore team.

// https://stackoverflow.com/questions/46744740/lodash-mongoose-object-id-difference/46745169

"Wait," you say, "what's the WTF about a comment pointing to a Stack Overflow page. I do that all the time?"

In this case, it's because this particular comment wasn't given any further explanation. It also wasn't in a block of code that was doing anything with either lodash, Mongoose, or set differences. It was, however, repeated multiple times throughout the codebase, because the entire codebase was a pile of copy-pasta glued together with the bare minimum code to make it work.

In at least one place, the comment was probably correct and helpful. But it got swept up as part of a broader copy/paste exercise, and now is scattered through the code without any true purpose.
