Example 1: mongofindoneandupate

try {
db.grades.findOneAndUpdate(
   { "name" : "A.B. Abracus" },
   { $set: { "name" : "A.B. Abracus", "assignment" : 5}, $inc : { "points" : 5 } },
   { sort: { "points" : 1 }, upsert:true, returnNewDocument : true }
);
}
catch (e){
   print(e);
}

Example 2: returned value by findOneAndUpdate

const filter = { age: 17 };
const doc = { $set: { name: "Naomi" } };
const options = { new: true };

Cat.findOneAndUpdate(filter, doc, options, (err, doc) => {
    if (err) console.log("Something wrong when updating data!");
    console.log(doc);
});

Example 3: findone and update mongoose

// Using queries with promise chaining
Model.findOne({ name: 'Mr. Anderson' }).
  then(doc => Model.updateOne({ _id: doc._id }, { name: 'Neo' })).
  then(() => Model.findOne({ name: 'Neo' })).
  then(doc => console.log(doc.name)); // 'Neo'

// Using queries with async/await
const doc = await Model.findOne({ name: 'Neo' });
console.log(doc.name); // 'Neo'
