# isNegativeNumberArray

> Test if a value is an array-like object containing only negative numbers.

<section class="usage">

## Usage

```javascript
var isNegativeNumberArray = require( '@stdlib/assert/is-negative-number-array' );
```

#### isNegativeNumberArray( value )

Tests if a `value` is an array-like object containing **only** negative numbers.

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

```javascript
var Number = require( '@stdlib/number/ctor' );

var bool = isNegativeNumberArray( [ -3.0, new Number(-3.0) ] );
// returns true

bool = isNegativeNumberArray( [ -3.0, '-3.0' ] );
// returns false
```

#### isNegativeNumberArray.primitives( value )

Tests if a `value` is an array-like object `array` containing **only** primitive negative numbers.

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

```javascript
var Number = require( '@stdlib/number/ctor' );

var bool = isNegativeNumberArray.primitives( [ -1.0, -5.0, -10.0 ] );
// returns true

bool = isNegativeNumberArray.primitives( [ -3.0, new Number(-1.0) ] );
// returns false
```

#### isNegativeNumberArray.objects( value )

Tests if a `value` is an array-like object `array` containing **only** object negative numbers.

<!-- eslint-disable no-new-wrappers, max-len -->

```javascript
var Number = require( '@stdlib/number/ctor' );

var bool = isNegativeNumberArray.objects( [ new Number(-1.0), new Number(-1.0) ] );
// returns true

bool = isNegativeNumberArray.objects( [ -1.0, -5.0, -10.0 ] );
// returns false
```

// returns true

// returns false

bool = isNegativeNumberArray( [ -1, 'abc', -3 ] );
// returns false

bool = isNegativeNumberArray( -78.0 );
// returns false
