# isNaNArray

> Test if a value is an array-like object containing only NaN values.


<section class="usage">

## Usage

``` javascript
var isNaNArray = require( '@stdlib/assert/is-nan-array' );
```

#### isNaNArray( value )

Tests if a `value` is an array-like object containing __only__ `NaN` values.

``` javascript
var bool = isNaNArray( [ NaN, NaN, NaN ] );
// returns true

bool = isNaNArray( [ NaN, 2 ] );
// returns false
```


#### isNaNArray.primitives( value )

Tests if a `value` is an array-like object containing __only__ primitive `NaN` values.

<!-- eslint-disable no-new-wrappers -->

``` javascript
var bool = isNaNArray.primitives( [ NaN, NaN, NaN ] );
// returns true

bool = isNaNArray.primitives( [ NaN, new Number( NaN ) ] );
// returns false
```

#### isNaNArray.objects( value )

Tests if a `value` is an array-like object containing __only__ object `NaN` values.

<!-- eslint-disable no-new-wrappers -->

``` javascript
var bool = isNaNArray.objects( [ new Number( NaN ), new Number( NaN ) ] );
// returns true

bool = isNaNArray.objects( [ NaN, new Number( NaN ) ] );
// returns false

bool = isNaNArray.objects( [ NaN, NaN, NaN ] );
// returns false
```
