    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-slice
```

</section>

<section class="usage">

## Usage

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

#### slice( x\[, start\[, end]] )

Returns a shallow copy of a portion of an array.

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

var out = slice( x );
// returns [ 1, 2, 3, 4, 5, 6 ]

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

The function accepts the following arguments:

-   **x**: input array.
-   **start**: starting index (inclusive). Default: `0`.
-   **end**: ending index (exclusive). Default: `x.length`.

By default, the function returns a shallow copy beginning from the first element of the provided input array. To begin copying from an alternative element, provide a starting index (inclusive).

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

var out = slice( x, 2 );
// returns [ 3, 4, 5, 6 ]
```

By default, the function copies through the end of the provided input array. To copy up until a specific element, provide an ending index (exclusive).

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

var out = slice( x, 1, 4 );
// returns [ 2, 3, 4 ]
```

<section class="notes">

## Notes

-   If provided an array-like object having a `slice` method, the function defers execution to that method and assumes that the method API has the following signature:

    ```text
    x.slice( start, end )
    ```

-   If provided an array-like object without a `slice` method, the function copies input array elements to a new generic array.

<!-- Package usage examples. -->

<section class="examples">

## Examples

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

```javascript
var Float64Array = require( '@stdlib/array-float64' );
var zeroTo = require( '@stdlib/array-zero-to' );
var slice = require( '@stdlib/array-slice' );

var x = zeroTo( 6, 'float64' );
// returns <Float64Array>[ 0.0, 1.0, 2.0, 3.0, 4.0, 5.0 ]

var s = slice( x );
// returns <Float64Array>[ 0.0, 1.0, 2.0, 3.0, 4.0, 5.0 ]

s = slice( x, 0, 4 );
// returns <Float64Array>[ 0.0, 1.0, 2.0, 3.0 ]

s = slice( x, 2 );
// returns <Float64Array>[ 2.0, 3.0, 4.0, 5.0 ]

s = slice( x, 2, 4 );
// returns <Float64Array>[ 2.0, 3.0 ]
```
