Why won't firstChild work for the code challenge?

Here's the code that works:

let myList = document.getElementsByTagName("ul")[0];
let firstListItem = myList.children[0];

Why wont the following code work? Doesn't it mean the same thing?

let myList = document.getElementsByTagName("ul")[0];
let firstListItem = myList.firstChild;

The "children" property returns only elements but the "firstChild" property returns the first node, which is not guaranteed to be an element.

What you probably want instead is "firstElementChild".
