Not sure how to select links within the element

This challenge requests: in the app.js file on line 1, select all links in the nav element and assign them to navigationLinks.

I don't know how to isolate the links in the nav element for my selection.

js/app.js 
let navigationLinks;
let galleryLinks;
let footerImages;
index.html 
<!DOCTYPE html>

  <head>
    <meta charset="utf-8">

This might be a good place to use the querySelectorAll function with a descendant selector as the argument. In a descendant selector, you name a containing element along with your target element(s) with a space in between them.

Happy coding!

I had trouble with this as well until I saw the answer on the first comment. I know answers arent supposed to be written without explanation but Steven Parker did a good job explaining it. Also, it was pretty self explanatory by just looking at it. Thanks to all you guys for all the great help! :)
