  /**
   * This function handles adding and removing a producer's product from the consumer's cart.
   * It checks whether the product is already in the cart and toggles its state accordingly.
   */

  // Check if the producer's product is not in the current cart
  if (currentCart.indexOf(producer.get("name")) === -1) {
    // Ensure the consumer has enough money in their wallet
    if (player.get("wallet") >= productPrice) {
      // Add the producer's product to the cart
      currentCart.push(producer.get("name"));

      // Check if the product has a warranty
      if (String(warrants.slice(-1)[0]).toUpperCase() === "TRUE") {
        // Deduct the product price plus warranty cost from the wallet
        player.set("wallet", player.get("wallet") - (productPrice + warrantCost));
      } else {
        // Deduct only the product price from the wallet
        player.set("wallet", player.get("wallet") - productPrice);
      }

      // Update the player's cart with the modified cart array
      player.set("cart", currentCart);

      // Notify the user that the product has been added to the cart
      toast("🛒 Product added to cart!");
    }
  } else if (currentCart.indexOf(producer.get("name")) !== -1) {
    // If the product is already in the cart, remove it and refund the money

    // Remove the product from the cart using a filter
    currentCart = currentCart.filter((p) => p !== producer.get("name"));

    // Update the player's cart with the modified cart array
    player.set("cart", currentCart);

    // Check if the product had a warranty
    if (String(warrants.slice(-1)[0]).toUpperCase() === "TRUE") {
      // Refund the product price plus warranty cost to the wallet
      player.set("wallet", player.get("wallet") + (productPrice + warrantCost));
    } else {
      // Refund only the product price to the wallet
      player.set("wallet", player.get("wallet") + productPrice);
    }

    // Notify the user that the product has been removed from the cart
    toast("🚮 Product removed from cart!");
  }

  // Debugging information (optional)
  // console.log("currentCart: ", currentCart);
}

Logic Explanation

1. Check if the product is already in the cart:

   • Uses currentCart.indexOf(producer.get("name")) to determine if the product is in the cart.
   • If not in the cart (-1), it adds the product to the cart.
   • If in the cart, it removes the product.

2. Handle wallet updates:

   • Deducts the product price (and warranty cost, if applicable) when adding a product.
   • Refunds the product price (and warranty cost, if applicable) when removing a product.

3. Update the cart and wallet:

   • Uses player.set("cart", currentCart) to update the cart.
   • Uses player.set("wallet", player.get("wallet") ± productPrice) to update the wallet balance.

4. Notifications:

   • Displays a toast message indicating whether the product was added or removed from the cart.
