# lodash._baseisequal v3.0.0
|
||||
|
||||
The [modern build](https://github.com/lodash/lodash/wiki/Build-Differences) of [lodash’s](https://lodash.com/) internal `baseIsEqual` 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._baseisequal
|
||||
```
|
||||
|
||||
In Node.js/io.js:
|
||||
|
||||
```js
|
||||
var baseIsEqual = require('lodash._baseisequal');
|
||||
```
|
||||
|
||||
See the [package source](https://github.com/lodash/lodash/blob/3.0.0-npm-packages/lodash._baseisequal) for more details.
