    About stdlib...
  </summary>
  <p>We believe in a future in which the web is a preferred environment for numerical computation. To help realize this future, we've built stdlib. stdlib is a standard library, with an emphasis on numerical and scientific computation, written in JavaScript (and C) for execution in browsers and in Node.js.</p>
  <p>The library is fully decomposable, being architected in such a way that you can swap out and mix and match APIs and functionality to cater to your exact preferences and use cases.</p>
  <p>When you use stdlib, you can be absolutely certain that you are using the most thorough, rigorous, well-written, studied, documented, tested, measured, and high-quality code out there.</p>
  <p>To join us in bringing numerical computing to the web, get started by checking us out on <a href="https://github.com/stdlib-js/stdlib">GitHub</a>, and please consider <a href="https://opencollective.com/stdlib">financially supporting stdlib</a>. We greatly appreciate your continued support!</p>

## Installation

```bash
npm install @stdlib/assert-is-numeric-array
```

</section>

<section class="usage">

## Usage

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

#### isNumericArray( value )

Tests if a value is a numeric array.

```javascript
var Int8Array = require( '@stdlib/array-int8' );

var bool = isNumericArray( new Int8Array( 10 ) );
// returns true

bool = isNumericArray( [ 1, 2, 3 ] );
// returns true

bool = isNumericArray( [ '1', '2', '3' ] );
// returns false
