DOM manipulation code challenge

'''use strict';

var list = document.getElementsByTagName('ul')[0];

list.addEventListener('click', function (e) { if (e.target.tagName == 'BUTTON') { var thatp = e.target.previousElementSibling; thatp.className += " highlight"; } });''

this code works but for some reason is not passing

I don't know why it doesn't pass, might be because you declare a variable but the task doesn't ask you do that. Tasks are pretty petty sometimes. I passed it with

e.target.previousElementSibling.className += 'highlight';
