Desktop like web apps and JS frameworks?
<p>I am still learning javascript and the more i learn the more i ask myself why do i need to learn a js framework like cappuccino, sproutcore, qooxdoo, smartclient etc...? The learning curve for these frameworks is steep, also wouldn't it be better to just make use of JavaScript libraries?</p>

<p>Take note, that my objective is to create desktop like web apps. Thanks in advance for any good view points!</p>
