## Overview

This is a lightweight browser-based ecommerce storefront. Users browse and filter a product catalog, view rendered products, and add items to a cart or wishlist; the cart persists in browser storage and can be displayed with a total. Reviews and analytics are also represented in the sampled code. Checkout, order history, profile, and admin pages exist in the tree, but their behavior and wiring are not shown. The graph omits speculative links for those pages and other unsampled integrations.

Main entry points: [`js/modules/render.js`](https://github.com/viratvasu0/simple-ecommerce-webapp/blob/main/js/modules/render.js) (Product rendering), [`js/modules/cart.js`](https://github.com/viratvasu0/simple-ecommerce-webapp/blob/main/js/modules/cart.js) (Cart), [`data/products.js`](https://github.com/viratvasu0/simple-ecommerce-webapp/blob/main/data/products.js) (Product data), [`js/modules/wishlist.js`](https://github.com/viratvasu0/simple-ecommerce-webapp/blob/main/js/modules/wishlist.js) (Wishlist)
