Cart Overview

How the E-commerce Website Works

Users can browse products, add them to their cart, and proceed to checkout. The cart stores products temporarily using state or localStorage and calculates totals on the fly.

Products are displayed from a static array or fetched via JSON/API.
Cart items are stored in an array or object with quantity tracking.
Users can view, update, or remove items from the cart.
Checkout form collects basic shipping information.
Optional: Save cart in localStorage to persist data on refresh.
