    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

```

<section class="usage">

## Usage

```javascript
var offsetView = require( '@stdlib/strided-base-offset-view' );
```

#### offsetView( x, offset )

Returns a typed array view having the same data type as a provided input typed array and starting at a specified index offset.

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

var x = new Float64Array( 10 );

var view = offsetView( x, 0 );
// returns <Float64Array>

var bool = ( view.buffer === x.buffer );
// returns true

var len = view.length;
// returns 10
```

The `offset` argument specifies the starting index of the returned typed array view relative to the input array `x`.

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

var x = new Float64Array( [ 1.0, 2.0, 3.0, 4.0, 5.0, 6.0, 7.0, 8.0 ] );

var view = offsetView( x, 2 );
// returns <Float64Array>

var len = view.length;
// returns 6

var v1 = view[ 0 ];
// returns 3.0

var v2 = view[ 1 ];
// returns 4.0
```

## Examples

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

```javascript
var Float64Array = require( '@stdlib/array-float64' );
var offsetView = require( '@stdlib/strided-base-offset-view' );

// Define a typed array:
var x = new Float64Array( [ 1.0, 2.0, 3.0, 4.0, 5.0, 6.0, 7.0, 8.0 ] );
// returns <Float64Array>

// Create a view of the array:
var view = offsetView( x, 0 );
// returns <Float64Array>

// Set view elements:
view[ 0 ] = 9.0;
view[ 1 ] = 10.0;

// Get the first two elements of the original array:
var v0 = x[ 0 ];
// returns 9.0

var v1 = x[ 1 ];
// returns 10.0
```
