How do I find get or reference specific <ul> tags when there are many?

It's easy to reference it in this code by just using document.querySelector('ul') because it's the only one. How do I find a specific one in more complex code with multiple <ul> tags?

To get a NodeList of all the <ul> elements on a page, you could do document.querySelectorAll('ul'). You could then select a particular node by its index number, such as document.querySelector('ul')[3].

You could add a class or id to the <ul> element, and select the element using the class or id.

You could change your selector to make it more specific, such as document.querySelector("nav ul").

If there are multiple ul's in the markup they will usually have classes or id's attributed to them , which you would use to select them by.

For instance: using the example were currently working with:

<ul class = "thisClass" aria-live="polite">

const x = document.querySelector('.thisClass');

console.log(x)

returns:
      <ul class = "thisClass" aria-live="polite">
       ....
      </ul>

If i understand your question well you're asking how to target a specific class if you have multiple classes of the same name, well I think the best way is using the qurerySelector() method. with that you'll be able to use more specific css selectors like nthchild and others to target your markup.

hope this helps.
