Hi, I Hope You're Well.
Core functionality: When the quantity of any item in the shopping cart is changed, the total price is recalculated in real time and the updated total, along with related details, is rendered on the same page without a full page reload. The output is returned to the user as a JSON response containing the item total, taxes, and the grand total.
Benefits: Faster user experience with seamless updates, reduced pricing errors at checkout, and simultaneous display of the updated total as quantities change.
How to use: The user adjusts the quantity of each product via the UI; the change is sent to the server via an AJAX request, the total price is recomputed, and the result is presented to the user.
Practical note: Designed for non-technical users to easily manage item quantities and see the exact price impact of each change.
Outcome: A smoother, error-free checkout experience with accurate pricing from start to finish.
