# lodash v3.10.1 The [modern build](https://github.com/lodash/lodash/wiki/Build-Differences) of [lodash](https://lodash.com/) exported as [Node.js](http://nodejs.org/)/[io.js](https://iojs.org/) modules. Generated using [lodash-cli](https://www.npmjs.com/package/lodash-cli): ```bash $ lodash modularize modern exports=node -o ./ $ lodash modern -d -o ./index.js ``` ## Installation Using npm: ```bash $ {sudo -H} npm i -g npm $ npm i --save lodash ``` In Node.js/io.js: ```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](https://github.com/lodash/lodash/tree/3.10.1-npm) for more details. **Note:**<br> Don’t assign values to the [special variable](http://nodejs.org/api/repl.html#repl_repl_features) `_` when in the REPL.<br> Install [n_](https://www.npmjs.com/package/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](https://www.npmjs.com/package/lodash),
