title: What is the difference between .on('click tap') and .on('click || tap')?
body: <p>What is the difference between </p>
  
  <pre><code>$('.classname').on('click tap', function(){});
  </code></pre>
  
  <p>and in the second case there is an OR sign ('||') between the events</p>
  
  <pre><code>$('.classname').on('click || tap', function(){});
  </code></pre>
  
  <p>Both seem to work fine but I would really like to know if adding an OR sign in the second case makes a difference?</p>
