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.
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
