## Overview

Modern Shopping Cart is a client-side React shopping-cart UI. Its main workflow initializes the app, displays sample products, lets shoppers change quantities, and recalculates item subtotals and the cart total; a separate star-rating interaction provides personalized feedback. The graph reflects the documented capabilities and the sampled component calls. No persistence, checkout processing, or backend integration is shown; the cart data is in-memory sample data.

Main entry points: [`src/App.jsx`](https://github.com/divyansh-attrii/react-shopping-cart/blob/main/src/App.jsx) (App composition), [`src/components/Cart.jsx`](https://github.com/divyansh-attrii/react-shopping-cart/blob/main/src/components/Cart.jsx) (Cart and totals), [`src/main.jsx`](https://github.com/divyansh-attrii/react-shopping-cart/blob/main/src/main.jsx) (React entry), [`src/components/CartItem.jsx`](https://github.com/divyansh-attrii/react-shopping-cart/blob/main/src/components/CartItem.jsx) (Cart item display)
