    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="usage">

## Usage

```javascript
var copyIndexed = require( '@stdlib/array-base-copy-indexed' );
```

#### copyIndexed( x )

Copies the elements of an indexed array-like object to a new "generic" array.

```javascript
var x = [ 1, 2, 3 ];

var out = copyIndexed( x );
// returns [ 1, 2, 3  ]

var bool = ( out === x );
// returns false
```

<section class="notes">

## Notes

-   An _indexed_ array-like object is a data structure in which one retrieves elements via integer indices using bracket `[]` notation (e.g., `Float64Array`, `Int32Array`, `Array`, etc). This is in contrast to an _accessor_ array-like object in which one retrieves elements using `get` and `set` methods (e.g., [`Complex64Array`][@stdlib/array/complex64] and [`Complex128Array`][@stdlib/array/complex128]).

<!-- Package usage examples. -->

## Examples

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

```javascript
var filledBy = require( '@stdlib/array-filled-by' );
var randu = require( '@stdlib/random-base-randu' );
var copyIndexed = require( '@stdlib/array-base-copy-indexed' );

// Create a Float64Array:
var arr = filledBy( 10, 'float64', randu );

// Copy elements to a generic array:
var out = copyIndexed( arr );

// Retrieve the first element:
var x = out[ 0 ];
// returns <number>

console.log( '%d', x );
