        const productId = btn.dataset.id;

        const productCountEl = document.querySelector(`.count[data-id="${productId}"]`);

        let productCount = parseInt(productCountEl.textContent);

        console.log('minus click')

        if (productCount > 0) {
            productCount--
            productCountEl.textContent = productCount;
            updateCart(productId, productCount);
        }
    }
    const minusFunction = () => {
        const minusBtns = document.querySelectorAll('.minus-btn');
        console.log('nothing');
        minusBtns.forEach(btn => btn.removeEventListener('click', minusItem));
        minusBtns.forEach(btn => {
            btn.addEventListener('click', () => minusItem(btn));
        });
    }
  
    function plusItem(btn) {
        const productId = btn.dataset.id;
        const productCountEl = document.querySelector(`.count[data-id="${productId}"]`);
        console.log(productCountEl)
        let productCount = parseInt(productCountEl.textContent);
        productCount++;
        productCountEl.textContent = productCount;
        updateCart(productId, productCount);
    }
    const plusFunction = () => {
        const minusBtns = document.querySelectorAll('.plus-btn');
        console.log('nothing');
        minusBtns.forEach(btn => btn.removeEventListener('click', plusItem));
        minusBtns.forEach(btn => {
            btn.addEventListener('click', () => plusItem(btn));
        });
    }
