    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>

> Zip one or more arrays to an array of composite views.

<section class="installation">

## Installation

```bash
npm install @stdlib/array-base-zip2views
```

</section>

<section class="usage">

## Usage

```javascript
var zip2views = require( '@stdlib/array-base-zip2views' );
```

#### zip2views( arrays, labels )

Zips one or more arrays to an array of composite views.

```javascript
var x = [ 1, 2, 3 ];
var y = [ 'a', 'b', 'c' ];

var labels = [ 'x', 'y' ];

var z = zip2views( [ x, y ], labels );
// returns [ <Object>, <Object>, <Object> ]

var v0 = z[ 0 ].toJSON();
// returns { 'x': 1, 'y': 'a' }

var v1 = z[ 1 ].toJSON();
// returns { 'x': 2, 'y': 'b' }

var v2 = z[ 2 ].toJSON();
// returns { 'x': 3, 'y': 'c' }

// Mutate one of the input arrays:
x[ 0 ] = 5;

v0 = z[ 0 ].toJSON();
// returns { 'x': 5, 'y': 'a' }

// Set a view property:
z[ 1 ].y = 'beep';

v1 = z[ 1 ].toJSON();
// returns { 'x': 2, 'y': 'beep' }

var y1 = y.slice();
// returns [ 'a', 'beep', 'c' ]
```

The function supports the following parameters:

-   **arrays**: list of arrays to zip.
-   **labels**: list of array labels.

Each element in the returned array is a class instance having prototype properties corresponding to the list of array labels. As demonstrated in the example above, to convert an element to a regular object, invoke an element's `toJSON` method. Note, however, that the object returned by an element's `toJSON` method no longer shares the same memory as the provided input arrays.

</section>

<!-- /.usage -->

<section class="notes">

-   The function assumes that the list of arrays to be zipped all have the same length.
-   The number of provided array labels should equal the number of arrays to be zipped.
-   Each view in the returned array shares the same memory as the corresponding elements in the input arrays. Accordingly, mutation of either an input array or a view will mutate the other.

## Examples

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

```javascript
var discreteUniform = require( '@stdlib/random-array-discrete-uniform' );
var zeroTo = require( '@stdlib/array-base-zero-to' );
var zip2views = require( '@stdlib/array-base-zip2views' );

var x = zeroTo( 10 );
var y = discreteUniform( x.length, -100, 100 );

var labels = [ 'x', 'y' ];

var out = zip2views( [ x, y ], labels );
// returns [...]
