IE11 'Blob is undefined' error
<p>I'm trying to download a file from the browser.</p>

<p>In JS I try to create a Blob from the data I get returned from the server but in IE11 the Blob is undefined and therefore cannot be created. </p>

<blockquote>
  <p>JS fails in this line with error : 'Blob' is undefined</p>
</blockquote>

<p>Works correctly in Chrome and Firefox.</p>

<pre><code>var blob = new Blob([data], {'type':"application/csv"});
</code></pre>

<p>Any suggestions?</p>
