> Detect native [`generator function`][generator-function] support.
<section class="usage">
## Usage
```javascript
var hasGeneratorSupport = require( '@stdlib/assert/has-generator-support' );
```
#### hasGeneratorSupport()
Detects if a runtime environment supports ES2015 [`generator functions`][generator-function], i.e. `function*()`.
```javascript
var bool = hasGeneratorSupport();
// returns <boolean>
```
