Determine if the JS environment has Symbol support. Supports spec, or shams.
## Example
```js
var hasSymbols = require('has-symbols');
hasSymbols() === true; // if the environment has native Symbol support. Not polyfillable, not forgeable.
var hasSymbolsKinda = require('has-symbols/shams');
hasSymbolsKinda() === true; // if the environment has a Symbol sham that mostly follows the spec.
```
## Supported Symbol shams
- get-own-property-symbols [npm](https://www.npmjs.com/package/get-own-property-symbols) | [github](https://github.com/WebReflection/get-own-property-symbols)
- core-js [npm](https://www.npmjs.com/package/core-js) | [github](https://github.com/zloirock/core-js)
## Tests
Simply clone the repo, `npm install`, and run `npm test`
