Calculating total in cypress - cypress

Question

I am trying to calculate the total price in the following way. However, when I log the total value at the bottom, I always get 0 logged.
I wish to store total in a variable so I can use it later on to compare values.
let total = 0;
cy.get('[cy-data="order-summary-products-product"]').each(
($product, index, $list) => {
const productQuantity = $product.attr("cy-data-product-quantity");
const productPrice = $product.attr("cy-data-product-price");
total += productPrice * productQuantity;
cy.wrap($product)
.find('[cy-data="order-summary-products-modifier"]')
.each(($modifier, index2, $list2) => {
const modifierQuantity = $modifier.attr("cy-data-modifier-quantity");
const modifierPrice = $modifier.attr("cy-data-modifier-price");
total += modifierPrice * modifierQuantity;
});
}
);
cy.log(total) //Always get 0 logged

Cypress has a env() method that you can use globally to store whatever you need.
Cypress.env('totalQuantity') = 0;
cy.get('[cy-data="order-summary-products-product"]').each(
($product, index, $list) => {
const productQuantity = $product.attr("cy-data-product-quantity");
const productPrice = $product.attr("cy-data-product-price");
Cypress.env('totalQuantity') += productPrice * productQuantity;
cy.wrap($product)
.find('[cy-data="order-summary-products-modifier"]')
.each(($modifier, index2, $list2) => {
const modifierQuantity = $modifier.attr("cy-data-modifier-quantity");
const modifierPrice = $modifier.attr("cy-data-modifier-price");
Cypress.env('totalQuantity') += modifierPrice * modifierQuantity;
});
});
