Shopping Cart
A shopping cart is a software component or feature in e-commerce systems that allows users to temporarily store and manage items they intend to purchase online. It functions as a virtual basket where customers can add, remove, or modify products before proceeding to checkout. This concept is fundamental to online retail, enabling a seamless shopping experience by simulating the physical act of collecting items in a store.
Developers should learn about shopping carts when building or maintaining e-commerce websites, mobile apps, or any platform involving online transactions. It's essential for implementing core functionalities like product selection, quantity adjustments, and price calculations before payment. Understanding this concept helps in integrating with payment gateways, managing user sessions, and ensuring data security for sensitive customer information.
