Using nextSibling()

Can i use this as a solution to the problem mentioned in the video-

 if (event.target.className == 'down') {
      let li = event.target.parentNode;
      let nextLi = li.nextElementSibling;
      if (nextLi) {
        let temp = nextLi ; 
        nextLi = li ; 
        li = temp;
      }

It looks like your code just changes the values in your variables. But the code in the video calls the "insertBefore" method to make changes happen on the page.

It just changes which elements the variables refer to.
