mongodbHow to use findoneandupdate in MongoDB?

MongoDB's findOneAndUpdate() method is used to find a single document and update it. It takes a filter, an update, and an optional options document as arguments. The filter is used to select the document to update, the update is used to specify the modifications to be made, and the options document can be used to specify additional options such as the sort order.

Example

db.collection.findOneAndUpdate(
   <filter>,
   <update>,
   {
     upsert: <boolean>,
     returnOriginal: <boolean>,
     sort: <document>,
     projection: <document>,
     maxTimeMS: <number>,
     ...
   }
)

Output example

{
   "_id" : ObjectId("5f3d2f8a7f8ea6d7f8b2d8fe"),
   "name" : "John Doe",
   "age" : 25,
   "status" : "A"
}
