JS framework with conditionally loaded fragments
<p>I'm doing a single-page, responsive, mobile first design. I found <a href="http://24ways.org/2011/conditional-loading-for-responsive-designs" rel="nofollow">this article</a> about conditionally loaded fragments but am wondering what the different js frameworks have build-in to handle this?</p>

<p>I'm imagining the mobile version with a list view fragment that transitions to a show view fragment. A larger portal could just show both fragments and change the show fragment when items in the list are clicked.</p>

<p>I'd love thoughts on what is available from the various frameworks, not an argument. Ember?, Angular?, etc. Maybe I'm missing it, but I'm not seeing the responsive fragments issue brought up in the various demos I've found so far.</p>
