title: jQuery .preventDefault and .stopPropagation used inside a function returning false
body: <p>jQuery <a href="http://learn.jquery.com/events/introduction-to-events/" rel="nofollow">documentation</a> states:</p>
  
  <p>"When utilizing both .preventDefault() and .stopPropagation() simultaneously, you can instead return false to achieve both in a more concise manner..."</p>
  
  <p>This is in regard to the example:</p>
  
  <pre><code>// Preventing a default action from occurring and stopping the event bubbling
  $( "form" ).on( "submit", function( event ) {
  
      // Prevent the form's default submission.
      event.preventDefault();
  
      // Prevent event from bubbling up DOM tree, prohibiting delegation
      event.stopPropagation();
  
      // Make an AJAX request to submit the form data
  
  });
  </code></pre>
  
  <p>My question is how does this work, the using of a " return false" in a function to prevent a form or a default action from occurring. Any references to official javascript documentation or jQuery documentation would be invaluable. </p>
