    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 [`iterable`][mdn-iterable-protocol]-like.

<section class="installation">

## Installation

```bash
npm install @stdlib/assert-is-iterable-like
```

</section>

<section class="usage">

## Usage

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

#### isIterableLike( value )

Tests if a `value` is [`iterable`][mdn-iterator-protocol]-like.

```javascript
var bool = isIterableLike( [] );
// returns <boolean>

bool = isIterableLike( {} );
// returns false
```

</section>

<!-- /.usage -->

<section class="notes">

## Notes

-   In order to be [iterable][mdn-iterable-protocol], an `object` must implement the `@@iterator` method, which, when called, returns an [iterator protocol-compliant object][mdn-iterator-protocol].
-   An [iterator protocol-compliant object][mdn-iterator-protocol] is an `object` having a `next` method following the [iterator protocol][mdn-iterator-protocol].
-   As full [iterator][mdn-iterator-protocol] compliance is **impossible** to achieve without evaluating an [iterator][mdn-iterator-protocol], this function checks **only** for interface compliance.
-   In environments lacking `Symbol.iterator` support, this function always returns `false`.

## Examples

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

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

var bool = isIterableLike( [] );
// returns <boolean>

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

bool = isIterableLike( null );
// returns false
