    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-base-fancy-slice
```

</section>

<section class="usage">

## Usage

```javascript
var slice = require( '@stdlib/array-base-fancy-slice' );
```

#### slice( x, s, strict )

Returns a shallow copy of a portion of an array.

```javascript
var Slice = require( '@stdlib/slice-ctor' );

var x = [ 1, 2, 3, 4, 5, 6 ];

var s = new Slice( 1, 4 );
var out = slice( x, s, false );
// returns [ 2, 3, 4 ]

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

The function supports the following parameters:

-   **x**: input array.
-   **s**: [slice][@stdlib/slice/ctor] object.
-   **strict**: boolean indicating whether to enforce strict bounds checking.

<section class="notes">

## Notes

-   If provided an array-like object having an unknown [data type][@stdlib/array/dtype], the function copies input array elements to a new generic array.

## Examples

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

```javascript
var zeroTo = require( '@stdlib/array-zero-to' );
var Slice = require( '@stdlib/slice-ctor' );
var slice = require( '@stdlib/array-base-fancy-slice' );

var x = zeroTo( 10, 'generic' );
// returns [ 0, 1, 2, 3, 4, 5, 6, 7, 8, 9 ]

var s = new Slice();
var y = slice( x, s, false );
// returns [ 0, 1, 2, 3, 4, 5, 6, 7, 8, 9 ]

s = new Slice( null, null, -2 );
y = slice( x, s, false );
// returns [ 9, 7, 5, 3, 1 ]

s = new Slice( -2, null, -2 );
y = slice( x, s, false );
// returns [ 8, 6, 4, 2, 0 ]

s = new Slice( 2, -2 );
y = slice( x, s, false );
// returns [ 2, 3, 4, 5, 6, 7 ]

s = new Slice( 2, 5 );
y = slice( x, s, false );
// returns [ 2, 3, 4 ]

s = new Slice( 4, 1, -1 );
y = slice( x, s, false );
// returns [ 4, 3, 2 ]

s = new Slice( 5 );
y = slice( x, s, false );
// returns [ 0, 1, 2, 3, 4 ]

s = new Slice( 5, null );
y = slice( x, s, false );
// returns [ 5, 6, 7, 8, 9 ]
