Objektify

The objektify module provides utility functions for working with objects. The following functions are provided: copy, extend, merge, mixin, and clone.

Usage

The copy function

The copy function copies all enumerable properties from a source object to a target object and returns the target object.

var copy = require("objektify").copy,
    obj = copy(new MyObject(), {foo: "bar"});

The extend function

The extend function creates a new object, sets the prototype and any extra properties provided, then returns the new object.

var extend = require("objektify").extend,
    proto = {foo: "bar"},
    obj = extend(proto, {bar: "bazz"});

The merge function

The merge function copies enumerable properties from a source object to a target object, but will not overwrite any properties set on the target which are not inherited.

var merge = require("objektify").merge,
    defaults = {foo: "bar", bar: "bazz"},
    obj = merge(new Foo(), defaults);

The mixin function

The mixin function copies enumerable properties from a mixin to a target without overwriting any properties on the target.

var mixin = require("objecktify").mixin,
    Mixin = require("my-mixin");

function Class() {
    Mixin.call(mixin(this, Mixin));
}

The clone function

The clone function clones a source object, creating a new object with the same prototype and with all enumerable properties copied over.

var clone = require("objektify").clone,
    MyFoo = require("my-foo"),
    foo = new MyFoo();

var cloned = clone(foo);
assert(cloned instanceof MyFoo);
