kodash

kodash
======


Knockout dependency detection in chained lodash (soon to be underscore as well) calls.

It's a simple extension of KnockoutJS which allows you to call lodash functions on observableArrays and observables.


Getting the value from the wrapper
==================================
``
var x = ko.observableArray([1,2,0,0,3,4,5]);
x._().filter().value();
//=>[1,2,3,4,5]
`


Mutating
========
Now let's say you want to mutate your observableArray
with the current value of your lodash calls

`
var x = ko.observableArray([1,2,0,0,3,4,5]);
x._().filter().mutate();
x();
//=>[1,2,3,4,5]
`
Making observableArrays
==================
`
var x = ko.observableArray([1,2,0,0,3,4,5]);
var y = x._().filter().observe();
x([1,2,0,0,3]);
y();
//=>[1,2,3]
`

Chaining dependencies
=====================
`
var x = ko.observableArray([1,2,3,4,5]);
var y = ko.observableArray([1]);
var z=x._().difference(y).observe();
z();
//=>[2,3,4,5]
`

But with another call
`
y([1,2]);
z();
//=>[3,4,5]
``

One thing to note. Lodash unwraps it's lodashWrapper class on certain calls. If you expect lodash to do this for one of your calls, make sure that you chain it.
