List of Object patterns for js (extracted from The Principles of Object-Oriented JavaScript, by Nicholas C.Zakas)

mixins.js

function mixin(receiver, supplier) {
    for (var property in supplier) {
        if (supplier.hasOwnProperty(property)) {
            receiver[property] = supplier[property]
        }
    }
    return receiver;
}

module_pattern.js

var person = (function () {
    //private stuff
    var age = 25;
    return {
        //public stuff
        name: "Nicholas",
        getAge: function () {
            return age;
        },
        growOlder: function () {
            age++;
        }
    };
}());

module_pattern_with_constructor.js

//If you want private data to be shared across all instances (as if it were on the prototype)
var Person = (function () {
    // everyone shares the same age
    var age = 25;
    function InnerPerson(name) {
        this.name = name;
    }

    InnerPerson.prototype.getAge = function () {
        return age;
    };

    InnerPerson.prototype.growOlder = function () {
        age++;
    };
    return InnerPerson;
}());
