    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>

## Usage

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

#### isVectorLike( value )

Tests if a value is a 1-dimensional [ndarray][@stdlib/ndarray/ctor]-like object.

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

var arr = ndarray( 'generic', [ 0, 0, 0, 0 ], [ 4 ], [ 1 ], 0, 'row-major' );
var bool = isVectorLike( arr );
// returns true
```

## Examples

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

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

var arr = ndarray( 'generic', [ 0, 0, 0, 0 ], [ 4 ], [ 1 ], 0, 'row-major' );
var out = isVectorLike( arr );
// returns true

out = isVectorLike( [ 1, 2, 3, 4 ] );
// returns false

out = isVectorLike( {} );
// returns false

out = isVectorLike( null );
// returns false
