title: Call a javascript function at distinct time intervals
body: <p>I've created a stock ticker function and need to call it every 2 minutes.</p>
  
  <p>I've succeeded in doing this with the javascript <code>setInterval</code> function, but the problem is on the first call it waits 2 minutes before calling the function, whereas I want the first load to be called right away.</p>
  
  <pre><code>function CallFunction() {
    setInterval("GetFeed()", 2000);
  }
  </code></pre>
