Use cases for updateOne over findOneAndUpdate in MongoDB [duplicate]

I think that findOneAndUpdate carries out an atomic operation, so I’m assuming that updateOne does not.

Why are you assuming that?

findOneAndUpdate returns a document whereas updateOne does not (it just returns the _id if it has created a new document).

I think that’s the main difference. So the use case of updateOne is when you don’t need the document and want to save a bit of time and bandwidth.
