THIS IS A TEMPORARY FORK OF LODASH FOR INTERNAL USE IN KIBANA

lodash v3.10.1

The modern build of lodash exported as Node.js/io.js modules.

Generated using lodash-cli:

$ lodash modularize modern exports=node -o ./
$ lodash modern -d -o ./index.js

Installation

Using npm:

$ {sudo -H} npm i -g npm
$ npm i --save lodash

In Node.js/io.js:

// load the modern build
var _ = require('lodash');
// or a method category
var array = require('lodash/array');
// or a method (great for smaller builds with browserify/webpack)
var chunk = require('lodash/array/chunk');

See the package source for more details.

Note: Don’t assign values to the special variable _ when in the REPL. Install n_ for a REPL that includes lodash by default.

Module formats

lodash is also available in a variety of other builds & module formats.

• npm packages for modern, compatibility, & per method builds
• AMD modules for modern & compatibility builds
• ES modules for the modern build
