```
In Node.js:
```js
// load the full build
var _ = require('lodash');
// load the core build
var _ = require('lodash/core');
// load the fp build for immutable auto-curried iteratee-first data-last methods
var _ = require('lodash/fp');
// or a method category
var array = require('lodash/array');
var object = require('lodash/fp/object');
// or method for smaller builds with browserify/rollup/webpack
var chunk = require('lodash/chunk');
var extend = require('lodash/fp/extend');
```
See the [package source](https://github.com/lodash/lodash/tree/4.1.0-npm) for more details.
**Note:**
Don’t assign values to the [special variable](http://nodejs.org/api/repl.html#repl_repl_features) `_` when in the REPL.
Install [n_](https://www.npmjs.com/package/n_) for a REPL that includes lodash by default.
