    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>

> Test if a value is an array-like object supporting the accessor (get/set) protocol.

<section class="intro">

An accessor array is defined as either an [`Array`][mdn-array], [`Typed Array`][mdn-typed-array], or an array-like [`Object`][mdn-object] (excluding `strings` and `functions`) having `get` and `set` methods for accessing array elements.

<section class="installation">

## Installation

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

</section>

<section class="usage">

## Usage

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

#### isAccessorArray( value )

Tests if a value is an array-like object supporting the accessor (get/set) protocol.

```javascript
var Complex128Array = require( '@stdlib/array-complex128' );
var Complex128 = require( '@stdlib/complex-float64-ctor' );

// Create a new complex number array:
var arr = new Complex128Array( 10 );

// Retrieve a complex number element:
var z = arr.get( 0 );
// returns <Complex128>

// Set a complex number element:
arr.set( new Complex128( 1.0, 1.0 ), 0 );

// ...

// Check whether an array is an accessor array:
var bool = isAccessorArray( arr );
// returns true
```
