db.collection('users').update({email : '[email protected]'},{data : {salary : 4000}})

//Query the database

db.collection('users').findOne({email : '[email protected]'});

/* OPERATION ON VALUES */

//Creates a new key value pair

db.set('myKey','myValue');

//Returns 'myValue'

db.get('myKey');

//Returns undefined

db.get('wrongKey');

//Deletes the myKey pair

db.unset('myKey');

/* OPERATIONS ON LISTS */

//Creates an empty list with 'myList' key

db.list('myList');

//pushes an element on the left of the list

db.rpush('myLyst','RIGHT');
