title: Scala to JavaScript compilation effective?
body: <p>I just read about the <a href="http://www.j2js.com/scala-demo/index.html" rel="nofollow noreferrer">java 2 javascript parser</a> and the demo with scala.</p>
  
  <p>Do you have any experience with this framework?</p>
  
  <p>What about performance?</p>
  
  <p>Can i use existing JS code/frameworks?</p>
  
  <p>I appreciate any help.</p>
  
  <h2>EDIT</h2>
  
  <p>This is a very good scala to javascript cross compiler:
