I have this two var abjects I created with raphael.js, and I am trying to pass this two variables into a a third one, but have no clue of how to do it. The script is supposed to resize the object based on its class (.awesome, awful) into its own canvas. I have created a http://jsfiddle.net/creativestudio/7uUgz/

    Congrats, you just leveled up as a programmer. You need to structure your code in functions. Functions reuse lines of code that do the same thing, only with a couple of parameters. There are several ways in which you could restructure your code, but here is a quick version:

    http://jsfiddle.net/emAUh/

    It should be easy to grasp for you because you have clearly defined the bits of reusable code with comments. Instead of doing this:

    /* ==|== AWESOME SMILE STARTS
/* ==|================================= */
    var awesome = paper.set();
    // ... draw everything 
// AWESOME SMILE ENDS

    You do this: 

    awesomeSmileGenerator(paper) {
  var awesome = paper.set();
  //draw everthing;
  return awesome;
}

    This allows you to do things later as…

    var face = awesomeSmileGenerator(paper);
console.log(face); //YOUR SET IS HERE, MAGIC!
