title: Best practice to trigger interval sequence
body: <p>Is there a better way to carry out a sequence of animations than using setTimeout intervals to trigger the next item in the sequence? </p>
  
  <pre><code>   setTimeout(function() { 
         // Do something 
      }, 300);
  
      setTimeout(function() { 
         // Do something 
      }, 600);
  
      setTimeout(function() { 
         // Do something 
      }, 900);
  </code></pre>
