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

Challenge 1

Could anyone provide any help on the following challenge as I'm unable to solve it. "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.)" When running my code it tells me I have selected the wrong links but when I run the code in the browser console I'm getting back an array of 3 elements which are pointing to the correct links as far as I can see. Any help on what I'm missing would be greatly appreciated

js/app.js 
let navigationLinks;
let galleryLinks;
let footerImages;

navigationLinks = document.querySelectorAll('nav li');
index.html 
<!DOCTYPE html>

Hi, I'm quite a 'newbie' so sorry if I confuse or am no help but I noticed you're not selecting the links (anchor tags) the question is asking for the links, not the list elements on their own?

Also in the hints it mentions using a descendent selector to choose descendent's of an element, ie; the Anchor Tags are children of the list elements etc

let children = node.children;

I hope I have been of some help in pointing you the right way!! I get stuck like this all the time!!

Hi Alex, you where absolutely right I was selecting the list elements and not the links. Once I corrected that I was able to pass without any issues :)
