    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

```bash
npm install @ffras4vnpm/eaque-deserunt-quod
```

Alternatively,

-   To load the package in a website via a `script` tag without installation and bundlers, use the [ES Module][es-module] available on the [`esm`][esm-url] branch (see [README][esm-readme]).
-   If you are using Deno, visit the [`deno`][deno-url] branch (see [README][deno-readme] for usage intructions).
-   For use in Observable, or in browser/node environments, use the [Universal Module Definition (UMD)][umd] build available on the [`umd`][umd-url] branch (see [README][umd-readme]).

The [branches.md][branches-url] file summarizes the available branches and displays a diagram illustrating their relationships.

To view installation and usage instructions specific to each branch build, be sure to explicitly navigate to the respective README files on each branch, as linked to above.

## Usage

```javascript
var assert = require( '@ffras4vnpm/eaque-deserunt-quod' );
```

#### assert

Namespace providing utilities for data type testing and feature detection.

```javascript
var o = assert;
// returns {...}
```

To validate the built-in JavaScript data types, the namespace includes the following assertion utilities:

</div>

<!-- </toc> -->

For primitive types having corresponding object wrappers, assertion utilities provide `isObject` and `isPrimitive` methods to test for either objects or primitives, respectively.

<!-- eslint-disable no-new-wrappers -->

```javascript
var Boolean = require( '@stdlib/boolean/ctor' );
var isBoolean = require( '@ffras4vnpm/eaque-deserunt-quod/is-boolean' );

var bool = isBoolean.isObject( new Boolean( false ) );
// returns true

bool = isBoolean.isObject( false );
// returns false

bool = isBoolean.isPrimitive( false );
// returns true
```

Many of the assertion utilities have corresponding packages that test whether array elements are of the given data type:

</div>

<!-- </toc> -->

Where applicable, similar to the assertion utilities for built-in data types, array assertion utilities provides methods for testing for an array of primitives or objects.

<!-- eslint-disable no-new-wrappers -->

```javascript
var isStringArray = require( '@ffras4vnpm/eaque-deserunt-quod/is-string-array' );

var bool = isStringArray( [ 'hello', 'world' ] );
// returns true

bool = isStringArray.primitives( [ 'hello', 'world' ] );
// returns true

bool = isStringArray.objects( [ 'hello', 'world' ] );
// returns false

bool = isStringArray.objects( [ new String( 'hello' ), new String( 'world' ) ] );
// returns true
```

The namespace also contains utilities to test for numbers within a certain range or for numbers satisfying a particular "type":
