JavaScript Error: Correcting 'each' Function Usage with 'closest' in jQuery

The problem with this code is that you are using the `each` function on the closest element, which will iterate over all matching elements. However, the `closest` function only returns the closest ancestor element that matches the given selector, so there is no need to iterate over it. \n\nTo fix this, you can simply remove the `each` function and directly assign the closest element to a variable. Here's the corrected code:\n\njavascript\nvar closestItem = $('#'+item_id).closest('.qcart_item');\n\n\nNow, `closestItem` will contain the closest element with the class `qcart_item` to the element with the given `item_id`.
