Using Javascript, Write a shopping cart constructor that allows you to create a shopping cart to include item names and their prices.

Write a function called cashRegister that takes a shopping cart object. The function should return the total price of the shopping cart.

Create multiple instances of the shopping cart object and show the results for each instance in your choice of display.

Update your Shopping Cart Object to add a taxable field to each item in the cart. Update your cashRegister function to apply 10% tax to the taxible items only, and outputs the correct total. Create multiple instances of the shopping cart object and show the results for each instance in your choice of display.
