How to append an attribute? :)

I think I've called the right list items (the ones with the attribute of external) - but now I want to add an attribute. Do I use append for that? How would I go about this?

js/app.js
$('#list li.external').append('target="_blank"');
index.html
<!DOCTYPE html>
<html>
<head>
  <link rel="stylesheet" href="css/style.css" type="text/css" media="screen" title="no title" charset="utf-8">
  <title>Links Page</title>
</head>
<body>
  <h1>Links</h1>
  <ul id='list' >
    <li><a href="http://google.com" class="external">Google</a></li>
    <li><a href="http://yahoo.com" class="external">Yahoo</a></li>
  </ul>
  <script src="//code.jquery.com/jquery-1.11.0.min.js" type="text/javascript" charset="utf-8"></script>
  <script src="js/app.js" type="text/javascript" charset="utf-8"></script>
</body>
</html>

:point_right: No, you want .attr() for that.

Append() is for inserting content (often another element) into an element.

Also, "li" stands for "list item". Links are "a" ("anchor") elements. So the selector for links with the class "external" would be: "a.external".

I realized your initial selector also needs some tweaking and updated my answer. :arrow_heading_up:
