    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

<section class="usage">

## Usage

```javascript
var isComplex128Array = require( '@stdlib/array-base-assert-is-complex128array' );
```

#### isComplex128Array( value )

Tests if a value is a [`Complex128Array`][@stdlib/array/complex128].

```javascript
var Complex128Array = require( '@stdlib/array-complex128' );

var arr = new Complex128Array( 10 );
var bool = isComplex128Array( arr );
// returns true
```

<section class="notes">

## Notes

-   This function is not robust and that is intentional. This function provides a lower cost way to reasonably determine whether an input value is a [`Complex128Array`][@stdlib/array/complex128] in order to avoid walking the prototype chain and resolving constructors, which is necessary for robust identification of cross-realm instances. For more robust validation, see [`@stdlib/assert-is-complex128array`][@stdlib/assert/is-complex128array].
