Tell us what’s happening:

You should create a calculateTotal method in the ShoppingCart class.

Above is the error mesage I am receiving.

Your code so far

<!-- file: index.html -->


/* file: styles.css */


/* file: script.js */
// User Editable Region

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

// User Editable Region

this.items is an invalid parameter name, you can’t use it there
