Describe the Issue

When working through the Shopping Cart Step 43, it's expected from the user to create a calculateTotal() method that internally uses a reduce() to make a sum, like the following:

calculateTotal() {
  const subTotal = this.items.reduce((total, item) => total + item.price, 0);
}

But when presented the following solution, making the reduce's callback sum the other way around, it doesn't pass:

calculateTotal() {
  const subTotal = this.items.reduce((total, item) => item.price + total, 0);
}

Your code

calculateTotal() {
  const subTotal = this.items.reduce((total, item) => item.price + total, 0);
}

Expected behavior

Because of the Commutative property of addition, the previous presented solution should work.
