title: Are Shared WebWorkers supported in IE 11?
body: <p>I tried to implement <a href="https://stackoverflow.com/a/36146764/702977">this code</a>, here is <a href="http://www.matrixlead.com/testWorker/fileA.html" rel="nofollow noreferrer">the link</a>. It works in Chrome, whereas in IE 11 it gives an error <code>'SharedWorker' is undefined</code>. But according to <a href="http://caniuse.com/#feat=webworkers" rel="nofollow noreferrer">caniuse</a>, WebWorkers are supported in IE 11. </p>
  
  <p>Does anyone know who is right?</p>
