Users.create({ name: 'virus24', age: 19 });


Users.update(
  user => user.age = 20,
  target => target.name === 'virus'

const user = Users.get(target => target.name === 'virus');
user.age = 20;
user.save();


Users.get(user => user.name === 'virus'); // { name: 'virus', age: 20 }
Users.getMany(user => user.age > 18); // [{ name: 'virus', age: 20 }, { name: 'virus24', age: 19 }]
