Review the build differences & pick the one that’s right for you.

• Modern build (minified) For new environments like Chrome, Firefox, IE ≥ 9, & Safari ≥ 5.1
• Compatibility build (minified) For new & old environments like IE ≤ 8 & PhantomJS

Installation

In a browser:

<script src="lodash.js"></script>

In an AMD loader:

require(['lodash'], function(_) {});

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

CDN copies are available on cdnjs & jsDelivr. Create custom builds with only the features you need. Looking for more functional usage? Try lodash-fp.
