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

Posted by Fanny Petersen

Need some help with this task.

In this challenge, you're going to select various elements from index.html. First, select all links inside the <nav> element and assign them to the variable navigationLinks. (HINT: Use a descendant selector to match elements that are descendants of an element.)

I don't understand why I'm suddenly supposed to use a method that was not introduced in the course?

js/app.js 
let navigationLinks;
let galleryLinks;
let footerImages;
index.html 
<!DOCTYPE html>
<html>
  <head>
    <meta charset="utf-8">
    <title>Nick Pettit | Designer</title>
    <link rel="stylesheet" href="css/normalize.css">
    <link href='http://fonts.googleapis.com/css?family=Changa+One|Open+Sans:400italic,700italic,400,700,800' rel='stylesheet' type='text/css'>

    <link rel="stylesheet" href="css/responsive.css">

  <body>

      <nav>
        <ul>

          <li id="3"><a href="contact.html">Contact</a></li>
        </ul>
      </nav>
    </header>
    <div id="wrapper">
      <section>
        <ul id="gallery">

let navigationLinks = document.querySelectorAll('nav a');;
let galleryLinks;
let footerImages;

You need to select all <a> element than are children of <nav> . To do that you need to use querySelectorAll with first parameter the parrent element/class/id then to make an empty space then to type the children element/class/id .
