    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 @stdlib/array-full
```

</section>

<section class="usage">

## Usage

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

#### full( length, value\[, dtype] )

Creates a filled array having a specified length.

```javascript
var arr = full( 2, 1.0 );
// returns <Float64Array>[ 1.0, 1.0 ]
```

By default, the output array [data type][@stdlib/array/dtypes] is `float64` (i.e., a [typed array][mdn-typed-array]). To specify an alternative [data type][@stdlib/array/dtypes], provide a `dtype` argument.

```javascript
var arr = full( 2, 1, 'int32' );
// returns <Int32Array>[ 1, 1 ]
```

## Examples

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

```javascript
var dtypes = require( '@stdlib/array-typed-real-dtypes' );
var full = require( '@stdlib/array-full' );

// Get a list of array data types:
var dt = dtypes();

// Generate filled arrays...
var arr;
var i;
for ( i = 0; i < dt.length; i++ ) {
    arr = full( 5, i+1, dt[ i ] );
    console.log( arr );
}
