Report a bunch of dragon that you saw.

You saw the following dragons:

• RedSpot
• FireBreath
• SnowedIce
• BlueJay

Let's conver this into an array of dragon first.

["RedSpot", "FireBreath", "SnowedIce", "BlueJay"]

In CoffeeScript this is as simple as:

    sky = ["RedSpot", "FireBreath", "SnowedIce", "BlueJay"]
    saw = (dragon) -> console.log(dragon);
    saw dragon for dragon in sky

Which is translated to JavaScript:

    var dragon, i, len, saw, sky;

    sky = ["RedSpot", "FireBreath", "SnowedIce", "BlueJay"];

    saw = function(dragon) {
      return console.log(dragon);
    };

    for (i = 0, len = sky.length; i < len; i++) {
      dragon = sky[i];
      saw(dragon);
    }

Generated code is pretty much the best piece of code, so thank js2.coffee
