title: Array.prototype.join not working in IE 8
body: <p>I have used the code snippet like below in my working scenario. It’s working fine in IE's latest versions but join function is not working in IE 8 Version.</p>
  
  <pre><code>&lt;!DOCTYPE html&gt;
  &lt;html xmlns="http://www.w3.org/1999/xhtml"&gt;
      &lt;head&gt;
          &lt;title&gt;&lt;/title&gt;
      &lt;/head&gt;
      &lt;body&gt;
          &lt;script type="text/javascript"&gt;
              var str = "TEST\n";
              var lines = str.split(/\r?\n/).join("\r\n");
              debugger;        
          &lt;/script&gt;
     &lt;/body&gt;
  &lt;/html&gt;
  </code></pre>
