require(["delite/Stateful"], function (Stateful) { new Stateful(); })
Base class for objects that provide named properties with optional getter/setter control and the ability to watch for property changes.
The class also provides the functionality to auto-magically manage getters
and setters for class attributes/properties. Note though that expando properties
(i.e. properties added to an instance but not in the prototype) are not supported.
Getters and Setters should follow the format of _setXxxAttr or _getXxxAttr where the xxx is a name of the attribute to handle. So an attribute of "foo" would have a custom getter of _getFooAttr and a custom setter of _setFooAttr. Setters must save and announce the new property value by calling this._set("foo", val), and getters should access the property value as this._fooAttr.

Examples
Example 1
var MyClass = dcl(Stateful, { foo: "initial" });
var obj = new MyClass();
obj.watch("foo", function(){
console.log("foo changed to " + this.foo);
});
obj.foo = bar;
// Stateful by default interprets the first parameter passed to
// the constructor as a set of properties to set on the widget
// immediately after it is created.Example 2
var MyClass = dcl(Stateful, { foo: "initial" });
var obj = new MyClass({ foo: "special"});- Source:
