I am confused... again

Am I on the right track here ? Or should I make another pot of coffee?

index.html 
<!DOCTYPE html>
<html>
    <head>
        <title>DOM Manipulation</title>
    </head>
    <link rel="stylesheet" href="style.css" />
    <body>
        <ul>
            <li id="first">First Item</li>
            <li id="second">Second Item</li>
            <li id="third">Third Item</li>
        </ul>
        <script src="app.js"></script>
    </body>
</html>
app.js 
let myList = document.querySelector('ul'); 
let firstListItem = $('li').first();

I don't think jQuery is available to the challenges in this course.

But there are still several ordinary JavaScript ways to get that first li element, including:

  • you could use querySelector, it returns the first element by default
  • you could get the children of myList, and then subscript it (index 0) to get the first one
  • you could use getElementById since it has the unique ID "first"
