Ex:
let collection = 'users';
let key = '_id';
let value = '1234567';

dbObj.delete(collection, key, value);  // returns a promise

Update object

let collection = 'users';
let key = '_id';
let value = '1234567';

dbObj.update(collection, key, value, {username: 'John Doe'});  // returns a promise

let criteria = {};
let projection = {};
let limit = 0; // 0 for getting all objects found.

dbObj.findInCollection(collection, criteria, projection, limit);  // returns a promise
