const productCards = document.querySelectorAll(".product-card");
productCards.forEach((productCard) => {

addButton.addEventListener("click", function () {

});
});
const checkoutButton = document.querySelector("#checkout-button");
checkoutButton.addEventListener("click", function () {

});
const cartItems = document.querySelector("#cart-items");
cartItems.addEventListener("click", function (event) {
if (event.target.tagName === "BUTTON") {
const productId = parseInt(event.target.parentNode.querySelector("h2").textContent.match(/\d+/)[0]);
cart = cart.filter((product) => product.id !== productId);
updateCart();
}
});
This code adds the following functionality:
1. *Product card generation*: The `generateProductCards` function generates product cards based on the `products` array.
2. *Add to cart functionality*: The `addProductToCart` function adds a product to the cart when the "Add to Cart" button is clicked.
3. *Cart updates*: The `updateCart` function updates the cart display when a product is added or removed.
4. *Checkout functionality*: The `checkout` function simulates a checkout process when the "Checkout" button is clicked.
5. *Event listeners*: The code adds event listeners to the product cards, cart items, and checkout button to handle user interactions.
Note that this is a basic implementation, and you may want to add more features, such as:
- User authentication and authorization
- Payment gateway integration
- Order management and tracking
- Product reviews and ratings
- Search and filtering functionality
