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

Stuck on Challenge Task 1 of 3, at the end of first segment of Javascript and the Dom

Can someone just tell me the answer? I cannot figure out the answer, and the site offers no way for me to move forward without the correct answer, nor will it show me the correct answer so I could review and understand it. I'm at a complete impasse with no way forward. PLEASE!

The hint is to use the descendant selector which is a space followed by your target(s) which is all links in the nav.

let navigationLinks = document.querySelectorAll('nav a');

Using nav a is done so you don't grab the anchors you don't need like the as in the gallery ul.

If you want a little more practice ---> https://www.w3schools.com/css/css_combinators.asp

Thank you Blake. I tried selecting ('nav li') which was incorrect, but was not told why exactly it was incorrect, nor offered any other option other than to try again. For the record, it is extremely, EXTREMELY irritating that Treehouse does not offer any other way to see simply see the answer in the event you get stuck. You cannot move on from a question without getting it right. God damn it.

Just to add on, you can search the specific challenges or videos in the community that have most likely been asked in the past and will have detailed answers on how to pass it.

In the community you can click the buttons that lead to similar questions. This one would be JavaScript > JavaScript and the DOM > Getting a Handle on the DOM > Practice Selecting Elements, and that will filter out the questions so it's all the questions in this track or this specific challenge set.

It looks like Blake already addressed your issue, but you should know how to skip ahead if you get stuck.

You can skip a challenge (or any course step) by clicking on the next circle on the progress bar that goes across the top of the page. The current page is represented by the circle with the ring around it.

If you're on the very last circle, you can skip to the next stage by going back to the course index using the link at the top left (above the bar with the circles). From there, you can go directly to any page in the course.

Thank you Steven for replying. I do know you can skip the entire segment, but you cannot complete a challenge segment or be shown the answer unless you get it correct.

The challenge itself may remain incomplete, but it won't hold you up. Sometimes if you move on, you'll learn something in later lessons that will allow you to come back later and complete the challenge.
