title: Ember: How to script with intervals
body: <p>I have a span-area like this</p>
  
  <pre><code>&lt;span class="blinky"&gt;I'm blinking&lt;/span&gt;
  </code></pre>
  
  <p>and now I want it to blink.
  In vanilla JS, I would write a simple piece of code using jQuery which starts an interval for this.</p>
  
  <p>However: <strong>How can I implement this in ember in a proper way?</strong></p>
