I do not understand why this line of code is not working:
p.className = "highlight";
var list = document.getElementsByTagName('ul')[0];
list.addEventListener('click', function(e) {
if (e.target.tagName == 'BUTTON') {
let button = e.target;
let p = button.previousElementSibiling;
p.className = "highlight";
}
});
