Class('Person', {
    
    methods : {
        eat : function (food) {
            console.log('yummy')
            
            return 'yummy'
        }
    }
})



Class('Person.Tidy', {
    isa : Person,
    
    before : {
        eat : function (food) {
            this.washHands()
        }
    },
    
    after : {
        eat : function (food) {
            this.brushTeeth()
        }
    },
    
    methods : {
    
        washHands : function (food) {
            console.log('washing hands')
        },
        
        brushTeeth : function (food) {
            console.log('brushing teeth')
        },
        
        eat : function (food) {
            this.SUPER(food)
        }
    }
})


var person = new Person.Tidy()

Joose is a self-hosting meta object system for JavaScript with support for classes, inheritance, roles (aka traits), method modifiers and much more.

The main goal of Joose is to make JavaScript Object Oriented Programming easier, more consistent and less tedious. With Joose you can to think more about what you want to do and less about the mechanics of OOP.

The Joose framework has been successfully used in multiple production systems for twelve months now and has been proven to be very stable. Joose is being tested using an automated unit-test suite that is being run in all major browsers (Firefox, IE, Safari, Opera and Chrome).

Joose also fully supports NodeJS platform.

Joose core package is only 8kb (YUI+gz).

From npm

[sudo] npm install joose --unsafe-perm=true

Many thanks to the whole Moose community for being icebreaker in the meta world.

Special thanks to Dave Rolsky for the excellent Moose documentation, on which this document is based.
