Need help with task

Hi! The task says select all links in the nav element. <nav> <ul> <li><a href="index.html" class="selected">Portfolio</a></li> <li><a href="about.html">About</a></li> <li><a href="contact.html">Contact</a></li> </ul> </nav> <footer> <li><a href="index.html">Portfolio</a></li> <li><a href="about.html">About</a></li> <li><a href="contact.html">Contact</a></li> </footer>

I can not make this one line. If I write: let navigationLinks = document.getElementsByTagName ("a"); I have error: Was expecting 3 links not 6 If I write: let nav = document.getElementsByTagName ("nav"); let navigationLinks = nav.getElementsByTagName ("a"); This gives an error: undefinet is not a function (evaluating 'nav.getElementsByTagName ("a")') If I am adding same class for all links inside nav elements and: let navigationLinks = document.getElementsByClassName("selected"); I have error: Was expecting 3 links not 1 Please help???

Hi men, you should apply this:

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

In this way you selected all the a links inside of nav element.
