Full Stack JavaScript Techdegree Graduate 15,990 PointsAm I thinking about this Correctly
I'm getting bummer: One or more of the buttons do not affect their previous sibling paragraphs.
Am I on the right track or way off?
var list = document.getElementsByTagName('ul')[0];
list.addEventListener('click', function(e) {
if (e.target.tagName == 'BUTTON') {
let button = event.target.parentNode;
let prevP = button.previousElementSibling;
let p = button.parentNode;
if(p){
p.className = "highlight";
}
}
});
