using nodejs cart price calculation

To calculate the total price of items in a cart using Node.js, you can follow these steps:

1. First, create a new Node.js project or navigate to an existing one.

2. Next, define the items in the cart and their prices, either by hardcoding them or retrieving them from a database or external source.

3. Then, write a function to iterate through the items in the cart and calculate the total price based on the quantity of each item and its price.

4. After that, implement any discounts or promotions that may apply to the items in the cart, adjusting the total price accordingly.

5. Finally, return or display the total price of the items in the cart, taking into account any discounts or promotions that have been applied.
