    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>

## Installation

```

<section class="usage">

## Usage

```javascript
var none = require( '@stdlib/array-base-none' );
```

#### none( x )

Tests whether all elements in an array are falsy.

```javascript
var x = [ 0, 0, 0, 0 ];

var bool = none( x );
// returns true
```

<!-- Package usage notes. Make sure to keep an empty line after the `section` element and another before the `/section` close. -->

<section class="notes">

## Notes

-   If provided an empty array, the function returns `true`.
-   The function does **not** skip `undefined` elements and is thus not optimized for sparse arrays.

<!-- Package usage examples. -->

## Examples

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

```javascript
var bernoulli = require( '@stdlib/random-array-bernoulli' );
var none = require( '@stdlib/array-base-none' );

var x = bernoulli( 10, 0.1, {
    'dtype': 'int8'
});
// returns <Int8Array>

var out = none( x );
// returns <boolean>
```
