Answer
updateOne() updates the first matching document using operators like $set, $inc, or $push.
Quick Answer
updateOne() updates the first document matching a filter. Takes two args: filter (which docs to match) and update (what to change). Use $set to change specific fields without replacing the whole document. Returns an object with matchedCount and modifiedCount. If you want to update all matching documents, use updateMany() instead.
