# Transform Scala lambda

[![Greenkeeper badge](https://badges.greenkeeper.io/xtuc/babel-plugin-transform-scala-lambda.svg)](https://greenkeeper.io/)

> Enable Scala lambda style

## Motivations

* Allow a more consice syntax for simple things.

* Scala is a great language (you should take a look at [Scala.js](http://www.scala-js.org))

## Installation

```sh

npm install --save-dev babel-plugin-transform-scala-lambda

```

## Usage

Add the following line to your .babelrc file:

```json

{

    "plugins": ["transform-scala-lambda"]

}

```

## Examples

### Sum a list of numbers

#### Using lambda style

```js

const sum = [1, 1, 1].reduce(_ + _);

```

#### Without it

```js

const sum = [1, 1, 1].reduce((a, b) => a + b);

```

### Get property from object

#### Using lambda style

```js

const users = [{ name: "Sven" }, { name: "James" }];

const userNames = users.map(_.name);

```

#### Without it

```js

const users = [{ name: "Sven" }, { name: "James" }];

const userNames = users.map(u => u.name);

```
