3,645 PointsUsing h1 for TagName
Since we can use "p" as a tag, could we use h1 like the the following? document.getElementsByTagName("h1")[1] I tryed it but it doesn't work
var fullName;
var lastName;
<!DOCTYPE html>
<html>
<head></head>
<body>
<h1 id="full_name"><span class="first_name">Andrew</span> <span class="last_name">Chalkley</span></h1>
<script src="app.js"></script>
</body>
</html>

47,913 PointsIn JavaScript, array indexes start counting from 0. Therefore, to get the first (and only, it seems) h1 element on the page, you would use this code:
//Notice the 0, instead of a 1
document.getElementsByTagName("h1")[0];

3,645 PointsIsn't "h1" [0] for first_name ? . Otherwise how would we access the first name using h1 Tag?

47,913 PointsIn your code, it would be getting both the span with the class "first_name" and the span with the class "last_name". Personally, if I was going to access the span with the class "first_name", I'd just do the following:
document.getElementsByClassName("first_name")[0];
However, if you want to access it by going through the h1, you could do something like this:
document.getElementsByTagName("h1")[0].getElementsByClassName("first_name")[0];
