title: What is the use of @jsControl helper in dust.js?
body: <p>I see that dust.js has @jsControl helper. Reference <a href="http://www.slideshare.net/veenabs/curious-case-of-dust" rel="nofollow">http://www.slideshare.net/veenabs/curious-case-of-dust</a> Slide #29. I would like to know what it is and when and where to use.
