title: What's the difference between e.preventDefault(); and return false?
body: <pre><code>$("a.avatar").click(function(e){
        e.preventDefault();
        $("#thumbnails").fadeIn();
      });
  </code></pre>
  
  <p>and </p>
  
  <pre><code>$("a.avatar").click(function(e){
        $("#thumbnails").fadeIn();
            return false;
      });
  </code></pre>
  
  <p>Both can achieve the same goal for me.</p>
