# lodash.where v3.0.0
|
||||
|
||||
The [modern build](https://github.com/lodash/lodash/wiki/Build-Differences) of [lodash’s](https://lodash.com/) `_.where` exported as a [Node.js](http://nodejs.org/)/[io.js](https://iojs.org/) module.
|
||||
|
||||
## Installation
|
||||
|
||||
Using npm:
|
||||
|
||||
```bash
|
||||
$ {sudo -H} npm i -g npm
|
||||
$ npm i --save lodash.where
|
||||
```
|
||||
|
||||
In Node.js/io.js:
|
||||
|
||||
```js
|
||||
var where = require('lodash.where');
|
||||
```
|
||||
|
||||
See the [documentation](https://lodash.com/docs#where) or [package source](https://github.com/lodash/lodash/blob/3.0.0-npm-packages/lodash.where) for more details.
