v3.1.1 -- 2017.03.15
* Improve documentation
* Improve error messages
* Update dependencies
v3.1.0 -- 2016.06.03
* Fix internals of symbol detection
* Ensure Symbol.prototype[Symbol.toPrimitive] in all cases returns primitive value
(fixes Node v6 support)
* Create native symbols whenver possible
v3.0.2 -- 2015.12.12
* Fix definition flow, so uneven state of Symbol implementation doesn't crash initialization of
polyfill. See #13
v3.0.1 -- 2015.10.22
* Workaround for IE11 bug (reported in #12)
v3.0.0 -- 2015.10.02
* Reuse native symbols (e.g. iterator, toStringTag etc.) in a polyfill if they're available
Otherwise polyfill symbols may not be recognized by other functions
* Improve documentation
v2.0.1 -- 2015.01.28
* Fix Symbol.prototype[Symbol.isPrimitive] implementation
* Improve validation within Symbol.prototype.toString and
Symbol.prototype.valueOf
v2.0.0 -- 2015.01.28
* Update up to changes in specification:
* Implement `for` and `keyFor`
* Remove `Symbol.create` and `Symbol.isRegExp`
* Add `Symbol.match`, `Symbol.replace`, `Symbol.search`, `Symbol.species` and
`Symbol.split`
* Rename `validSymbol` to `validateSymbol`
* Improve documentation
* Remove dead test modules
v1.0.0 -- 2015.01.26
* Fix enumerability for symbol properties set normally (e.g. obj[symbol] = value)
* Introduce initialization via hidden constructor
* Fix isSymbol handling of polyfill values when native Symbol is present
* Fix spelling of LICENSE
* Configure lint scripts
v0.1.1 -- 2014.10.07
* Fix isImplemented, so it returns true in case of polyfill
* Improve documentations
v0.1.0 -- 2014.04.28
* Assure strictly npm dependencies
* Update to use latest versions of dependencies
* Fix implementation detection so it doesn't crash on `String(symbol)`
* throw on `new Symbol()` (as decided by TC39)
v0.0.0 -- 2013.11.15
* Initial (dev) version

# es6-symbol
## ECMAScript 6 Symbol polyfill
For more information about symbols see following links
- [Symbols in ECMAScript 6 by Axel Rauschmayer](http://www.2ality.com/2014/12/es6-symbols.html)
- [MDN Documentation](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Symbol)
- [Specification](http://people.mozilla.org/~jorendorff/es6-draft.html#sec-symbol-constructor)
### Limitations
Underneath it uses real string property names which can easily be retrieved, however accidental collision with other property names is unlikely.
### Usage
If you'd like to use native version when it exists and fallback to [ponyfill](https://ponyfill.com) if it doesn't, use *es6-symbol* as following:
```javascript
var Symbol = require('es6-symbol');
```
If you want to make sure your environment implements `Symbol` globally, do:
```javascript
require('es6-symbol/implement');
```
If you strictly want to use polyfill even if native `Symbol` exists (hard to find a good reason for that), do:
```javascript
var Symbol = require('es6-symbol/polyfill');
```
#### API
Best is to refer to [specification](http://people.mozilla.org/~jorendorff/es6-draft.html#sec-symbol-objects). Still if you want quick look, follow examples:
```javascript
var Symbol = require('es6-symbol');
var symbol = Symbol('My custom symbol');
var x = {};
x[symbol] = 'foo';
console.log(x[symbol]); 'foo'
// Detect iterable:
var iterator, result;
if (possiblyIterable[Symbol.iterator]) {
iterator = possiblyIterable[Symbol.iterator]();
result = iterator.next();
while(!result.done) {
console.log(result.value);
result = iterator.next();
}
}
```
### Installation
#### NPM
In your project path:
$ npm install es6-symbol
##### Browser
To port it to Browser or any other (non CJS) environment, use your favorite CJS bundler. No favorite yet? Try: [Browserify](http://browserify.org/), [Webmake](https://github.com/medikoo/modules-webmake) or [Webpack](http://webpack.github.io/)
## Tests [![Build Status](https://travis-ci.org/medikoo/es6-symbol.png)](https://travis-ci.org/medikoo/es6-symbol)
$ npm test
