Mascara JavaScript

Generated Javascript 1.2

// this is some sample Mascara JavaScript
// the second line should generate a warning
var x : int = 17;
var y : int = 18.5;

// example of generics:
var d = new Array.<Date>;
d[1] = new Date();
d[2] = "hello"; // error!

// nullable types
var a : ?boolean = null; // OK!
var b : !Object = null; // error!

// example of classes and inheritance:
class Car {
   var color : String;
   function Car(color : String) { 
     this.color = color; 
   }
}
class Volvo extends Car {
    function Volvo() : super("red") {}
}

var v : Car = new Volvo();
v.color;
