title: Is plain vanilla JavaScript better than using frameworks like jQuery or MooTools?
body: <p>I am wondering if it is a good idea to rely on frameworks like jQuery or <a href="http://en.wikipedia.org/wiki/MooTools" rel="noreferrer">MooTools</a> or should we just use plain JavaScript?</p>
  
  <p>Apart from avoiding the re-invention of wheel, do they add any specific value?</p>
  
  <p>Since the frameworks are open to the public, can there be possibility of exploitation of any security holes that might appear (of course, unintentionally :) ) in the frameworks?</p>
  
  <p>Are there any other points that are to be considered when choosing a framework or otherwise?</p>
