Learn Basic OOP by Building a Shopping Cart - Step 48

Tell us what’s happening:

The command asks: Declare a variable tax and assign it the value of calling your new .calculateTaxes() method, passing subTotal as the argument.

My code

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

And it gives me an error and tells me the following:

Assign the value of calling your new .calculateTaxes() method, passing subTotal as the argument, to the tax variable.

I need help, I have already tried several things and I don’t know what else to do.

It looks as if you havent chained a method to the function, in other words you need this. Good luck

Remember that calculateTotal and calculateTaxes are both methods of the ShoppingCart class. In the subTotal line you referred to items (which is a property of the ShoppingCart class) using correct syntax. Bearing this in mind, try writing the const tax line again

Thanks for your answer!! I just tried the following code, and it didn’t work:

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

And it keeps giving me the same error:
Assign the value of calling your new .calculateTaxes() method, passing subTotal as the argument, to the tax variable.

Exact! I also assigned it to the tax variable, but it didn’t work. I don’t know which variable I should assign the .calculateTaxes() method to, and that is what is causing me confusion.

Here is some information about what you need to do:

I hope this helps!

Thank you so much! I read the article and was able to solve it!! I used the this as a global reference so I could assign the method!
