what's the difference between these two javascript calls?
<p>what does the 'function' do in the following:</p>

<pre><code>$('.event-row').on('mouseover',function(){
  arc.event_handler.event_row_over();
  });

$('.event-row').on('mouseover',arc.event_handler.event_row_over );
</code></pre>

<p>thx in advance</p>
