title: Jquery replace text every 2 seconds with words from an array
body: <p>I want to replace a text in a span with the id "words" with words from an array every 2 seconds</p>
  
  <pre><code>$('#words').delay(1000).fadeOut(1000);
      $(this).delay(3000).text('word2').fadeIn(1000);
  $(this).delay(5000).text('word3').fadeIn(1000);
  $(this).delay(7000).text('word4').fadeIn(1000);
  </code></pre>
  
  <p>This is what I've got but obviously it stops working after 7 seconds.. how can I repeat this? Or even use an array to hold the words.. Thank you!</p>
