    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>

<section class="installation">

## Installation

```bash
npm install @stdlib/assert-is-finite-array
```

</section>

<section class="usage">

## Usage

```javascript
var isFiniteArray = require( '@stdlib/assert-is-finite-array' );
```

#### isFiniteArray( value )

Tests if a `value` is an array-like object containing **only** finite `numbers`.

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

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

var bool = isFiniteArray( [ -3.0, new Number(3.0) ] );
// returns true

bool = isFiniteArray( [ -3.0, 'abc' ] );
// returns false

bool = isFiniteArray( [ -3.0, 1.0/0.0 ] );
// returns false
```

#### isFiniteArray.primitives( value )

Tests if a `value` is an array-like object containing **only** primitive finite `numbers`.

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

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

var bool = isFiniteArray.primitives( [ -1.0, 0.0, 4.5 ] );
// returns true

bool = isFiniteArray.primitives( [ -1.0, 1.0/0.0 ] );
// returns false

bool = isFiniteArray.primitives( [ -3.0, new Number(2.0) ] );
// returns false
```

#### isFiniteArray.objects( value )

Tests if a `value` is an array-like object containing **only** `Number` objects having finite values.

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

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

var bool = isFiniteArray.objects( [ new Number(-1.0), new Number(2.0) ] );
// returns true

bool = isFiniteArray.objects( [ -1.0, 0.0, 1.0 ] );
// returns false

bool = isFiniteArray.objects( [ -3.0, new Number(1.0) ] );
// returns false
```

## Examples

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

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

```javascript
var Number = require( '@stdlib/number-ctor' );
var isFiniteArray = require( '@stdlib/assert-is-finite-array' );

var bool = isFiniteArray( [ -5.0, 0.0, 2.0, 5.0 ] );
// returns true

bool = isFiniteArray( [ -4.0, -3.14, 1.0, 3.14 ] );
// returns true

bool = isFiniteArray( [ -1.0, new Number( -6.0 ), 2.0 ] );
// returns true

bool = isFiniteArray( [ -1.0, 'abc', 3.0 ] );
// returns false

bool = isFiniteArray( [ -2.3, 1.0/0.0, 3.0 ] );
// returns false

bool = isFiniteArray( [] );
// returns false
