title: Target="_blank" vs window.open
body: <p>I'm working on an application where users enter some input and they shouldn't leave the page when clicking on share links, e.g. a Facebook share link:</p>
  
  <pre><code>&lt;a href="https://www.facebook.com/sharer.php?u=http%3A%2F%2Fwww.example.com%2F"&gt;Share on Facebook&lt;/a&gt;
  </code></pre>
  
  <p>I know it's very common to use popup windows for such links. But does it have any advantage over a simple <code>target="_blank"</code> attribute? How do you compare the two methods and which is the right practice in such cases?</p>
