I have been stuck on this question can anyone help me?

Question

var s = document.
getElementsByTagName("span");
for(var x=0; x<s.length;x++) {
s[_].style.backgroundColor = "#33EA73";
}

Answer 1

Just replace s[_] with s[x]

One tips : actually it's a bad practice to compute length on every iteration
Better idea is to cache it. Find below the code snippet for for-loop
for(var x = 0, l = s.length; x < l; x = x + 1){
s[x].style.backgroundColor = "#33EA73";
}

Answer 2

Never mind i just figured it out

Answer 3

Ok
