[![NPM version](https://badge.fury.io/js/es-symbol.svg)](http://badge.fury.io/js/es-symbol)

[![Build Status](https://secure.travis-ci.org/goatslacker/es-symbol.svg)](http://travis-ci.org/goatslacker/es-symbol)

[![Coverage Status](https://img.shields.io/coveralls/goatslacker/es-symbol.svg?style=flat)](https://coveralls.io/r/goatslacker/es-symbol)

[![Dependency Status](https://david-dm.org/goatslacker/es-symbol.svg)](https://david-dm.org/goatslacker/es-symbol)

* No unnecessary dependencies

* Works in node + browser (IE8--Modern browsers)

* Uses native `Symbol` if possible otherwise exports a polyfill

## Usage

```sh

npm install es-symbol

```

```js

var Symbol = require('es-symbol')

var sym = Symbol('foo')

var obj = {}

obj[sym] = 'hello'

// The following are true

obj.foo === undefined

obj[sym] === 'hello'

```

Disclaimer: This depends on ES5. If you need to support legacy browsers consider using an ES5 shim.
