title: In AngularJS, how do I optionally wrap item in a link
body: <p>I have a person with a name and an optional home page. How do I optionally wrap their name in an anchor tag?</p>
  
  <pre><code>&lt;ul ng-repeat='person in people'&gt;
    &lt;li&gt;
      &lt;a href="{{person.website}}"&gt;
        {{person.name}}
      &lt;/a&gt;
    &lt;/li&gt;
  &lt;/ul&gt;
  </code></pre>
  
  <p>or in the case where <code>person.website</code> is nil</p>
  
  <pre><code>&lt;ul ng-repeat='person in people'&gt;
    &lt;li&gt;
      {{person.name}}
    &lt;/li&gt;
  &lt;/ul&gt;
  </code></pre>
  
  <p>In rails I would use the method <code>&lt;%= link_to_unless person.website.blank?, seller.name, seller.website %&gt;</code></p>
  
  <p>How do I do this in AngularJS?</p>
