Here's a few hints to help you solve it yourself:

  • a convenient way to select elements is with the document.querySelectAll() method
  • the instructions already hint to use a descendant selector as the method argument
  • a descendant selector is where you have a container and target selector separated by a space
  • you want the <a> elements inside the <nav>, so the container is "nav" and the target is "a"
  • assign the result of calling the method to the variable navigationLinks
