es-symbol

A spec-compliant as much as it could be, small, and tested ES6 Symbol implementation.

• No unnecessary dependencies
• Works in node + browser (IE8--Modern browsers)
• Uses native Symbol if possible otherwise exports a polyfill

Usage

npm install es-symbol

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.
