title: What is the difference between $() and $.?
body: <p>I would like to figure out the difference between using <code>$()</code>  and <code>$.</code> from other developers.</p>
  
  <p>As far as my understanding goes, <code>$()</code> refers to objects within the <code>DOM</code>, but I am not <code>100%</code> clear as to how the <code>$.</code> works. I have used the <code>$.</code> format before, but never understood how it works. </p>
  
  <p>For example:</p>
  
  <p><code>$.each(element, function() {});</code> or <code>$.fn</code> etc...</p>
  
  <p>It would be nice to shed some light and clarity on this topic.</p>
