title: HTML5 Javascript API Intellisense support in visual studio
body: <p>I started playing with HTML5/CSS3 and the new JavaScript API</p>
  
  <p>something i noticed in VS 2010 is it doesn't have any support for the new JavaScript API i was wondering if there is anything i can do about it</p>
  
  <p>so in Vs2010 if i type :</p>
  
  <pre><code>     var canvas = document.getElementById('diagonal');
       var context = canvas.getContext('2d');
  </code></pre>
  
  <p>i don't get any intellisense for the "getContext" method etc..</p>
  
  <p>i dont wanna write the code and compile and pray it works.</p>
  
  <p>any idea how can i enable intellisense for new javascript ?</p>
