How to update and return document in MongoDB?

To update and return document in MongoDB, we can call findAndUpdare with the returnOriginal option set to false.

For instance, we write

collection.findOneAndUpdate({
    code
  }, {
    $set: updatedFields
  }, {
    returnOriginal: false
  },
  (err, documents) => {
    //...
    db.close();
  }
);

to call findOneAndUpdate to update the entries with code set to code with the updatedFields object values.

We set returnOriginal to false so that documents in the callback would return the updated versions of the updated documents.

Finally, we call db.close to close the database connection.
