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

How do you retrieve a list within a navigation with only one variable declaration?

I went through the entire tutorial regarding different ways of selecting items from the HTML but none of them went specifically over this. How did you approach it? What other tutorials can you recommend?

The return of a list vs. a single element is based on the method used. For example, document.querySelector returns one single element, but document.querySelectorAll returns an HTMLcollection, which is essentially a list of elements.

The latter when used with a descendant selector ("nav a") is a good solution for task 1 of the challenge.

You can use " document.querySelectorAll("nav li") ", where the value "nav li" is called the descendent selector which means that select all <li> element that is inside <nav> element; You can also use it with other HTML elements like "nav a" meaning select all anchor (<a>) element that is inside <nav> elements.

And for selecting elements in HTML use can watch:-

  2. JavaScript and the DOM
  3. DOM scripting with example

Close, except that "li" elements are list items, but the challenge is asking for links.

oh I just read the question and thought that the question is to select the list items with in <nav> elements.
