|
## Usage
|
||
|
|
||
|
```javascript
|
||
|
var isNumberArray = require( '@stdlib/assert/is-number-array' );
|
||
|
```
|
||
|
|
||
|
#### isNumberArray( value )
|
||
|
|
||
|
Tests if a `value` is an array-like object of `numbers`.
|
||
|
|
||
|
```javascript
|
||
|
var bool = isNumberArray( [ 1, 2, 3, 4 ] );
|
||
|
// returns true
|
||
|
```
|
||
|
|
||
|
#### isNumberArray.primitives( value )
|
||
|
|
||
|
Tests if a `value` is an array-like object containing **only** `number` primitives.
|
||
|
|
||
|
<!-- eslint-disable no-new-wrappers -->
|
||
|
|
||
|
```javascript
|
||
|
var Number = require( '@stdlib/number/ctor' );
|
||
|
|
||
|
var bool = isNumberArray.primitives( [ 1, 2, 3 ] );
|
||
|
// returns true
|
||
|
|
||
|
bool = isNumberArray.primitives( [ 1, new Number( 2 ), 3 ] );
|
||
|
// returns false
|
||
|
```
|
||
|
|
||
|
#### isNumberArray.objects( value )
|
||
|
|
||
|
Tests if a `value` is an array-like object containing **only** `Number` objects.
|
||
|
|
||
|
<!-- eslint-disable no-new-wrappers -->
|
||
|
|
||
|
```javascript
|
||
|
var Number = require( '@stdlib/number/ctor' );
|
||
|
|
||
|
var bool = isNumberArray.objects( [ new Number( 1 ), new Number( 2 ) ] );
|
||
|
// returns true
|
||
|
|
||
|
bool = isNumberArray.objects( [ new Number( 1 ), 2 ] );
|
||
|
// returns false
|
||
