Example 2: 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'
