This below quiz is from changing elements.
What is the array number? And how to find it?

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

Answer 1

x.
s contains an array of span elements. you are looping from 0 until the last index of the array and storing that in x. so s[x]. style.etc is what you want.
