title: Which way to test if an element is checked is better? .is(':checked') or .prop('checked')
body: <p>Both <code>.is(':checked')</code> and <code>.prop('checked')</code> can be used to test if a checkbox is checked.</p>
  
  <p>Are there any interesting/important differences between those two ways of querying the <em>checked</em> state or is it pretty much only a matter of personal preference?</p>
