lodash-deep

Lodash mixins for (deep) object accessing / manipulation.

Version 2.x

In 2.0 most of the methods of this module where removed, because Lodash now supports their functionality natively. E.g.:

_.deepGet(object, 'father.name');
// ->
_.get(object, 'father.name');

_.deepPluck(array, 'father.name');
// ->
_.map(array, 'father.name');

Compatibility

lodash-deep is currently compatible with:

• Node.js
• All ES5 compatible browsers (IE9+, Chrome, Firefox, Safari etc)

Installation

Bower

1. bower install lodash-deep
2. Reference lodash-deep.min.js after lodash.min.js

Node.js

1. npm install lodash
2. npm install lodash-deep

3. var _ = require("lodash");
   _.mixin(require("lodash-deep"));

            level3: {
                value: 'value 3'
            }
