in this video,
// 4: Using traversal, store the second-to-last list item in a variable named prevItem
const prevItem = lastItem.previousElementSibling; prevItem.style.backgroundColor = '#f36f49';
it used this code but in my mind, the previous element sibling of the last item is third item, not a second item. and not a second-to-last list item, only the third item. why it's like this? please let me understand this. thank you so much for everybody!!

If there are four items, the third item is also the "second-to-last" one.
