How to show "cart is empty" after all items have been removed using Javascript?

by

I am a bit stuck and hoping someone can help me, please.

Basically I have coded a shopping cart and am currently trying to get the cart to display a message saying "Cart is empty" after all of the cart items have been removed.

Everything is working ok apart from the "Cart is empty" message being re-displayed after the cart is empty.

I have tried a few things but cannot seem to get the emptyCartMessage to display when removing the last cart item.

Just for extra context my cart items each have an independent ‘remove’ button attached to them.

My code is below.

Thank you for any help, I do appreciate it!

const currentCartItems = document.getElementsByClassName('cart-item');
const emptyCartMessage = document.createElement('p');
emptyCartMessage.innerHTML = 'Your cart is empty.';


// EMPTY CART ITEM DISPLAY MESSAGE
shoppingCart.appendChild(emptyCartMessage);
    



// SHOPPING AREA BUTTON EVENT LISTENER

for (var i = 0; i < addToCartButton.length; i++) {
    addToCartButton[i].addEventListener('click', createCartItem);
    
}


function createCartItem(event) {

    //CREATE CART LI ITEM
    const newItem = document.createElement('li');
    newItem.className = 'cart-item';
    //newItem.innerHTML = event.target.value;

    //GET AND SET SHOP/CART ITEM VALUE 
    const itemValue = document.createElement('p');
    itemValue.innerHTML = event.target.value;

    //CREATE CART ITEM DESCRIPTION 
    const p = document.createElement('p');
    p.innerHTML = itemDescription;

    //CREATE CANCEL CART ITEM BUTTON
    const cancelItemImage = document.createElement('img');
    cancelItemImage.className = "remove-button";
    cancelItemImage.src = "images/cancel-icon.png";
    cancelItemImage.alt = "red remove icon";
   
    newItem.appendChild(itemValue);
    newItem.appendChild(p);
    newItem.appendChild(cancelItemImage);

    shoppingCart.appendChild(newItem);

    if (currentCartItems.length > 0) {
        emptyCartMessage.className = 'hide-empty-cart';
    } else if (currentCartItems.length <= 0) {
        emptyCartMessage.classList.remove('hide-empty-cart');
    }
    
}

    is a little vanilla. You might peek at Yahoo’s front page and note how they
    create news titles to grab viewers to open the links. You might try
    adding a video or a picture or two to grab people excited about what
    you’ve got to say. In my opinion, it might make your website a little bit more interesting. http://herreramedical.org/vidalista
