    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-array-like
```

</section>

<section class="usage">

## Usage

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

#### isArrayLike( value )

Tests if a value is [array-like][array-like].

<!-- eslint-disable object-curly-newline -->

```javascript
var bool = isArrayLike( [] );
// returns true

bool = isArrayLike( { 'length': 10 } );
// returns true
```

If provided a `string`, the function returns `true`.

```javascript
var bool = isArrayLike( 'beep' );
// returns true
```

## Examples

<!-- eslint-disable object-curly-newline, no-restricted-syntax, no-empty-function -->

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

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

var bool = isArrayLike( { 'length': 10 } );
// returns true

bool = isArrayLike( [] );
// returns true

bool = isArrayLike( 'beep' );
// returns true

bool = (function test() {
    return isArrayLike( arguments );
})();
// returns true

bool = isArrayLike( null );
// returns false

bool = isArrayLike( void 0 );
// returns false

bool = isArrayLike( 5 );
// returns false

bool = isArrayLike( true );
// returns false

bool = isArrayLike( {} );
// returns false

bool = isArrayLike( function noop() {} );
