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

The goal is to select the links within the list elements, not the list elements themselves.

Let me know if this helps here

We want to select all the a elements within the nav.

We write this the same way we would in CSS which is 'nav a'. Use this string for the parameter for querySelectorAll().

That's not quite right.

Your answer originally had 'nav li'.

You're right. I was conflating an answer I gave for a different question dealing with lists just before this one.

Sorry for the confusion.
