# isNegativeIntegerArray

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

<section class="usage">

## Usage

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

#### isNegativeIntegerArray( value )

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

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

```javascript
var bool = isNegativeIntegerArray( [ -3, new Number(-3) ] );
// returns true

bool = isNegativeIntegerArray( [ -3, '3.0' ] );
// returns false
```

#### isNegativeIntegerArray.primitives( value )

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

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

```javascript
var bool = isNegativeIntegerArray.primitives( [ -1.0, -10.0 ] );
// returns true

bool = isNegativeIntegerArray.primitives( [ -1.0, 0.0, -10.0 ] );
// returns false

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

#### isNegativeIntegerArray.objects( value )

Tests if a `value` is an array-like object containing **only** `Number` objects holding negative `integer` values.

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

```javascript
var bool = isNegativeIntegerArray.objects( [ new Number(-1.0), new Number(-10.0) ] );
// returns true

bool = isNegativeIntegerArray.objects( [ -1.0, 0.0, -10.0 ] );
// returns false

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

## Examples

<!-- eslint no-undef: "error" -->

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

var bool = isNegativeIntegerArray( [ -5, -2, -3 ] );
// returns true

bool = isNegativeIntegerArray( [ -4, -3, -2, -1 ] );
// returns true

bool = isNegativeIntegerArray( [ -1, new Number( -6 ), -3 ] );
// returns true

bool = isNegativeIntegerArray( [ -3, -2, -1, 0 ] );
// returns false

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

bool = isNegativeIntegerArray( [ -2.3, -1, -3 ] );
// returns false

bool = isNegativeIntegerArray( [] );
// returns false
