How am I supposed to assign three links that inside of the nav tag, to the variable navigationLinks?

Whenever I try "document.getElementsByTagName('nav')" I select one link of three. How can I select three of them?

js/app.js 
let navigationLinks;
let galleryLinks;
let footerImages;
index.html 
<!DOCTYPE html>
<html>
  <head>
    <meta charset="utf-8">
    <title>Nick Pettit | Designer</title>

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

You weren't selecting a link there. Links are implemented with anchor (a) elements. And there's only one "nav" element, which is what you were asking for.

This is a good place to use "querySelectorAll", since it takes a CSS-style selector and a descendant selector can be used to specifically target the links (a) that are inside the nav.
