title: How different is Ext JS from others like jQuery and Mootools
body: <p>When looking at Ext JS, I don't get the feeling that it's meant for the same things as jQuery and Mootools.</p>
  
  <p>Whilst jQuery and Mootools help with the general workings of a site, Ext JS seems to be focussed on tables and storing data, plus manipulating it.</p>
  
  <p>So, is this observation correct, or is Ext Js fit for the same work as jQuery and Mootools?</p>
