How do I get my code to return all three links? My code: let navigationLinks = document.getElementsByTagName('nav');

When my code appears as follows, i get the error "Was expecting 3 links not 1": let navigationLinks = document.getElementsByTagName('nav');

I'm not sure why it's not returning all the elements with in <nav></nav>?

js/app.js 
let navigationLinks = document.getElementsByTagName('nav');
let galleryLinks;
let footerImages;

There are multiple navs on the page, as you are selecting them, you are actually selecting multiple, so you need to specify which one, its the first nav on the page, so it would be index of 0. Then you need to get the links nested inside that nav. theres many ways to do it. But heres one. 

let navigationLinks= document.getElementsByTagName('nav')[0].getElementsByTagName('a');
let galleryLinks;
let footerImages;
