title: jQuery alternative to $.each
body: <p>I found that the $.each is very slow and makes problems to the web pages if containing lot of various jQuery effects.</p>
  
  <p>I'd like to know if there is a good alternative to the $.each, for example:</p>
  
  <pre><code>$('ul li').each(function() {
     var singleLi = $(this);
  });
  </code></pre>
  
  <p>without the hover, how can I do the same without using each?</p>
  
  <p>Thanks.</p>
