Joose is an open-source self-hosting meta object system for JavaScript with support for classes, inheritance, mixins, traits and aspect oriented programming.

The Joose meta-object system is multi-paradigm. It supports class-based and prototype-based programming styles as well as class-based inheritance and role-based extension. While other JavaScript frameworks often specialize on DOM-access and AJAX, Joose specializes solely on bringing successul programming techniques to the JavaScript programming language. Joose is thus often used in conjunction with another DOM/Ajax JavaScript framework and is tested with jQuery, YUI, Dojo, ExtJS, Prototype, Mootools and PureMVC.

Joose was heavily inspired by Moose, the object system for Perl 5 which was itself inspired by Perl 6 object system, but unlike Perl and Moose, Joose doesn't support multiple inheritance.

Example

Two classes written in Joose:

Class("Point", {
    has: {
        x: {is: "rw"},
        y: {is: "rw"}
    },
    methods: {
        clear: function () {
            this.setX(0);
            this.setY(0);
        }
    }
});
 
Class("Point3D", {
    isa: Point,
    has: {
        z: {is: "rw"}
    },
    after: {
        clear: function () {
            this.setZ(0);
        }
    }
});

Point3D is a subclass of Point. It has another attribute defined and additional code to run after running the superclass clear() method. The "rw" means the attribute is readable and writable with a pair of get/set accessors generated automatically.
