# nonEnumerablePropertyNames

> Return an array of an object's own non-enumerable property names.

<section class="usage">

## Usage

<!-- eslint-disable id-length -->

```javascript
var nonEnumerablePropertyNames = require( '@stdlib/utils/nonenumerable-property-names' );
```

#### nonEnumerablePropertyNames( obj )

Returns an `array` of an object's own non-enumerable property names.

```javascript
var defineProperty = require( '@stdlib/utils/define-property' );

var obj = {
    'a': 'b'
};

defineProperty( obj, 'c', {
    'configurable': false,
    'enumerable': false,
    'writable': true,
    'value': 'd'
});

var keys = nonEnumerablePropertyNames( obj );
// returns [ 'c' ]
```

</section>

<!-- /.usage -->

<section class="notes">

## Notes

-   Name order is not guaranteed, as `object` key enumeration is not specified according to the [ECMAScript specification][ecma-262-for-in].  practice, however, most engines use insertion order to sort an `object`'s keys, thus allowing for deterministic extraction.

## Examples
