The documentation here doesn't provide much of an explanation for why there are two different operations to accomplish the same thing, so I'm wondering what the differences are between them. Why might I choose to use one over the other?
This function differs slightly from Model.findOneAndRemove() in that findOneAndRemove() becomes a MongoDB findAndModify() command, as opposed to a findOneAndDelete() command. For most mongoose use cases, this distinction is purely pedantic. You should use findOneAndDelete() unless you have a good reason not to.
