1st question.... Yay! "You didn't set the `target` attributes on the `.external` links." I think I did, any help?

I thought this was straight forward I might need to use .attr() but at this point I'm lost.

I would like just a hint if possible :D

js/app.js 
var $target = ('target="_blank"');

$(".external").append('$target');
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>
    <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>

Hey Spencer,

You are close. You just need to take what you are doing with 2 lines of code and put it into one. And, you are right in needing to use attr. 

$(".external").attr("target", "_blank");

Hope that helps. Keep Coding! :)

You will need to use the .attr() method.

Here is a hint on how to use this method

$(".external").attr("attribute_name", "attribute_value");

"attribute name" will be the attribute you are trying to target. ("target").

"attribute value" will be the value you are trying to pass. ("_blank")

I hope this helps.
