Answer

1. Simple JSON Object

const shopCart = {
  items: 0,
  list: [],
};

2. Using Object constructor

const shopCart = new Object();

3. Using Function

const ShopCartClass = function () {
  this.items = 0;
  this.list = [];
};

const cart = new ShopCartClass();

4. Using Class

class ShopCartClass {
  this.items = 0;
  this.list = [];
};

const cart = new ShopCartClass();

5. Using Object.create(null) to inherit from the null object and remove all prototype methods

const cart = Object.create(null);

6. Using IIFE (Immediately Invoked Function Expression)

const cart = new (function () {
  this.items = 0;
  this.list = [];
})();
