const db = require('quick.db');
// Pushing an element to an array (that doesn't exist yet) in an object:
db.push('userInfo.items', 'Sword')
// -> { difficulty: 'Easy', items: ['Sword'] }
// Repeating previous examples:
db.push('userInfo.items', 'Watch')
// -> { difficulty: 'Easy', items: ['Sword', 'Watch'], balance: 500 }
// Fetching individual properties
db.get('userInfo.items') // ['Sword', 'Watch']
