JavaScript JavaScript and the DOM (Retiring) Getting a Handle on the DOM Practice Selecting Elements

Is there a method for selecting the children of an html element with no class? Say, a nav element?

I feel like having to create a loop for the sake of selecting all child elements of a parent is a bit excessive. Is there a way of doing this with less code?

I'm stuck here, as it seems like Gil didn't show me how to do this in the videos prior to this challenge.

Maybe I'm wrong. What am I missing?

js/app.js 
let navigationLinks = document.querySelectorAll('nav:child');
let galleryLinks;
let footerImages;
index.html 
<!DOCTYPE html>
<html>
  <head>
    <meta charset="utf-8">

You can use the children property. It's a read-only property that returns all the children from a parent element, inside a HTMLCollection. They can be retrieved similar to values in an Array. For example, if you wanted to get the nav, you could something like:

var headerChildren = document.querySelector("header").children,
nav = headerChildren[1];
