Obi

Obi is a simple object builder that allows you to compose objects together with immutability.
AKA Obi will build an object out of other objects without altering the object references you gave it.
It also does its best to deeply clone an object. See lodash's cloneDeep method for more details.

API

You use Obi by requiring the obi module

var obi = require('obi');

obi

either give obi an object to wrap or just invoke obi. obi will use an empty object by default. The cool part here is that obi will return an method to keep extending the object.
obi() or obi({foo: 'foo'}) will return the extend and done methods for the object state.

extend

if you want to keep building on top of that object, use extend to immutably extend the object. The cool part is obi will recursively return new obi objects while cloning the object you pass in.

obj = obi()
obj.extend({foo: 'foo'}) # => obi({foo: 'foo'})

done

once you're done extending the object you created with obi, use done to return the final object

obj = obi()
obj.extend({foo: 'foo'}).extend({bar: 'bar'}).done() # => {foo: 'foo', bar: 'bar'}
