    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 [ndarray][@stdlib/ndarray/ctor]-like.

<section class="installation">

## Installation

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

</section>

<section class="usage">

## Usage

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

#### isndarrayLike( value )

Tests if a value is [ndarray][@stdlib/ndarray/ctor]-like.

```javascript
var ndarray = require( '@stdlib/ndarray-ctor' );

var arr = ndarray( 'generic', [ 0, 0, 0, 0 ], [ 2, 2 ], [ 2, 1 ], 0, 'row-major' );
var bool = isndarrayLike( arr );
// returns true
```

A value is [ndarray][@stdlib/ndarray/ctor]-like if a value is an `object` with the following properties:

-   **dtype**: `string` specifying a data type.
-   **data**: `object` pointing to an underlying data buffer.
-   **shape**: array-like `object` containing dimensions.
-   **strides**: array-like `object` containing stride lengths.
-   **offset**: `number` specifying the index offset.
-   **order**: `string` describing the memory layout.
-   **ndims**: `number` specifying the number of dimensions.
-   **length**: `number` specifying the total number of elements.
-   **flags**: `object` containing meta data.
-   **get**: `function` for retrieving elements.
-   **set**: `function` for setting elements.

## Examples

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

```javascript

var arr = ndarray( 'generic', [ 0, 0, 0, 0 ], [ 2, 2 ], [ 2, 1 ], 0, 'row-major' );
var bool = isndarrayLike( arr );
// returns true

bool = isndarrayLike( [ 1, 2, 3, 4 ] );
// returns false

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

bool = isndarrayLike( null );
// returns false
