body: <p>Found the answer some some of my problems, html5 web workers!!!</p>
  
  <p>How do I pass an argument to a web worker though using this basic example?</p>
  
  <p>contents of worker.js:</p>
  
  <pre><code>function doSomething() {
      postMessage( ' done');
  }
  setTimeout ( "doSomething()", 3000 );
  </code></pre>
  
  <p>js code:</p>
  
  <pre><code> var worker = new Worker('worker.js');
    worker.onmessage = function (event) {
      alert(event.data);
    };
  </code></pre>
