# lodash.intersectionby v4.0.0
|
||||
|
||||
The [lodash](https://lodash.com/) method `_.intersectionBy` exported as a [Node.js](https://nodejs.org/) module.
|
||||
|
||||
## Installation
|
||||
|
||||
Using npm:
|
||||
```bash
|
||||
$ {sudo -H} npm i -g npm
|
||||
$ npm i --save lodash.intersectionby
|
||||
```
|
||||
|
||||
In Node.js:
|
||||
```js
|
||||
var intersectionBy = require('lodash.intersectionby');
|
||||
```
|
||||
|
||||
See the [documentation](https://lodash.com/docs#intersectionBy) or [package source](https://github.com/lodash/lodash/blob/4.0.0-npm-packages/lodash.intersectionby) for more details.
