I did not understand whats wrong there are. Probobly ı have not understood the question clearly.

app.js 
const list = document.getElementsByTagName('ul')[0];

list.addEventListener('click', function(e) {
  if (e.target.tagName == 'BUTTON ') {
    let li = e.target.parentNode;
      let beforeLi = li.previousElementSibling;
    let ul = li.parentNode;
    ul.insertBefore(li, beforeLi);
  }
});

The instructions say that "a class of highlight should be added to the paragraph element".

So you won't need to insert any elements. Just change the class attribute of the paragraph.
