    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>

> Cumulatively test whether at least one element in a provided array is truthy.

<section class="installation">

## Installation

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

</section>

<section class="usage">

## Usage

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

#### cuany( x )

Cumulatively tests whether at least one element in a provided array is truthy.

```javascript
var x = [ false, false, true, false, false ];

var y = cuany( x );
// returns [ false, false, true, true, true ];
```

#### cuany.assign( x, out, stride, offset )

Cumulatively tests whether at least one element in a provided array is truthy and assigns results to a provided output array.

```javascript
var x = [ false, false, true, false, false ];
var y = [ false, null, false, null, false, null, false, null, false, null ];

var out = cuany.assign( x, y, 2, 0 );
// returns [ false, null, false, null, true, null, true, null, true, null ]

var bool = ( out === y );
// returns true
```

The function supports the following parameters:

-   **x**: input array.
-   **out**: output array.
-   **stride**: output array stride.
-   **offset**: output array offset.

## Examples

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

```javascript
var bernoulli = require( '@stdlib/random-array-bernoulli' );
var cuany = require( '@stdlib/array-base-cuany' );

// Create an array of random values:
var x = bernoulli( 10, 0.1 );
console.log( x );

// Cumulatively determine whether values are truthy:
var out = cuany( x );
console.log( out );
```
