title: Different ways of saying document ready in jQuery?
body: <p>Are these both the same thing, i.e. ways of saying document ready:</p>
  
  <pre><code>$(function() {
    //
  });
  </code></pre>
  
  <p>and </p>
  
  <pre><code>$(function($) {
     //
  })(jQuery);
  </code></pre>
  
  <p>or is there a difference between the two, if so then when should I use which?</p>
