title: Running javascript standalone engine?
body: <p>Bit of a strange question here i know.</p>
  
  <p>but i wanted to know if some kind of standalone engine for javascript exists..</p>
  
  <p>basically i want to test running of my javascript without having to load a web page...</p>
  
  <p>Maybe it doesn't exist? Like some kind of ide where i can run commands directly without launching IE etc...</p>
  
  <p>I have a great editor but it doesn't support that.. i still need to launch ie / firefxo</p>
  
  <p>What i was thinking of some kind of standalone javascript engine existed that i could write my code here and make debugging a bit easier... and then copy to my webpage.</p>
  
  <p>I know firebug exists but you can't specifically do what i am asking cna you?</p>
  
  <p>Any ideas?</p>
