title: What has happened to javascript helper in cakePHP 2?
body: <p>I have used this <a href="http://bakery.cakephp.org/articles/agusti/2010/02/02/transparent-datepicker-with-jquery" rel="nofollow noreferrer">item</a> and get this error :</p>
  <pre><code>Missing Helper
  Error: JavascriptHelper could not be found.
  Error: Create the class JavascriptHelper below in file: app/View/Helper/JavascriptHelper.php
  &lt;?php
       class JavascriptHelper extends AppHelper {
   }
  </code></pre>
  <p>Well indeed, this file does not exists, and I tried to use 'Js' in my helper array.</p>
  <pre><code>class myClassController expend AppController {
      var $helpers = array('Html', 'Js'); // and not 'Javascript');
  </code></pre>
  <p>In the code, the method <code>$this-&gt;Javascript-&gt;codeBlock</code> is called to add a javascript method (in the middle of the content instead of the header) but there is no $this-&gt;Js-&gt;codeBlockcodeBlock either.</p>
  <pre><code>$output .= $this-&gt;Js-&gt;codeBlock(&quot;datepick('&quot; . $htmlAttributes['id'] . &quot;','01/01/&quot; . $options['minYear'] . &quot;','31/12/&quot; . $options['maxYear'] . &quot;');&quot;);
      
  </code></pre>
  <p>Could you explain me what happened to the old Javascript helper or how to get the code working?</p>
  <p>Is there an other helper which could work with CakePHP-2.0?</p>
  <p>Cordially,</p>
