Is there an error in the code?

Shouldn't there be 2 times .parentNode in the last part of code? Seems, that having it once (like in the video) doesn't remove the whole box only some of the elements.

const li = e.target.parentNode.parentNode;

ul.addEventListener('click', (e) => {
  if (e.target.tagName === 'BUTTON') {
    const li = e.target.parentNode.parentNode;
    const ul = li.parentNode;
    ul.removeChild(li);
  }
});

The parent of the button is the list item, so there should only be one "parentNode" when creating the "li" reference.

You didn't refer to the video, but I'm guessing that the intent of the button is to remove only the list item the button is on, not the whole list.
