Cart Functionality refers to the feature that allows users to add products they intend to purchase to a virtual cart. This cart functionality is present in websites that have a shopping cart or checkout page, either using a known ecommerce platform or a custom solution. The cart stores information about the user's selected items and their quantities until they are ready to proceed to the checkout process. Users can add or remove items from their cart as necessary before checking out. Cart functionality also facilitates the calculation of the total cost of the products in the cart by adding up their prices and any applicable taxes, shipping fees, or discounts. Once the user is satisfied with the contents of their cart, they can proceed to checkout where they enter their shipping information, payment details, and complete their purchase. This functionality enhances the user experience by allowing users to browse multiple products at once and make purchases at their convenience without having to complete each transaction individually.

How to use Cart Functionality
Cart functionality is an essential feature for any shopping website. When a customer adds items to the cart, it allows them to keep track of their intended purchases before completing the checkout process.
To implement cart functionality on your website, you can either use a known ecommerce platform like Shopify, WooCommerce, or Magento, or build a custom solution using web technologies.
Here are some general steps to follow for building a custom cart functionality:
Store Cart Data: You need to store the cart data somewhere such as cookies, local storage, session storage or server-side database depending on your application architecture.
Add Items to the Cart: When customers click on the "Add to Cart" button for a product, you should create a new item object representing that product and add it to the cart. This can be done through AJAX calls or server-side requests.
Display Cart Items: Your website should display the cart items in a user-friendly way so that the customer can easily see what they have added to the cart.
Update Cart: The customer should be able to update the cart by changing the quantity or removing items from it.
Calculate Totals: The cart should calculate the total cost of all items and display it to the customer.
Checkout Process: When the customer is ready to check out, the cart should pass the necessary information to the checkout page such as shipping address, payment method, etc.
Order Confirmation: After the customer completes the order, the cart should show an order confirmation page with the details of the purchase.
In summary, cart functionality is an essential feature for any eCommerce website, and it requires storing cart data, adding items to the cart, displaying cart items, updating the cart, calculating totals, facilitating the checkout process and displaying an order confirmation page. Whether you use a pre-built ecommerce platform or custom solution, make sure to test thoroughly to ensure that it works smoothly for your customers.
