@stdlib/assert-is-arraybuffer

About stdlib...

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.

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.

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.

To join us in bringing numerical computing to the web, get started by checking us out on GitHub, and please consider financially supporting stdlib. We greatly appreciate your continued support!

isArrayBuffer

Test if a value is an ArrayBuffer.

Installation

npm install @stdlib/assert-is-arraybuffer

Usage

var isArrayBuffer = require( '@stdlib/assert-is-arraybuffer' );

isArrayBuffer( value )

Tests if a value is an ArrayBuffer.

var ArrayBuffer = require( '@stdlib/array-buffer' );

var bool = isArrayBuffer( new ArrayBuffer( 10 ) );
// returns true

bool = isArrayBuffer( [] );
// returns false

Examples

var Float32Array = require( '@stdlib/array-float32' );
var Float64Array = require( '@stdlib/array-float64' );
var Int8Array = require( '@stdlib/array-int8' );
var Int16Array = require( '@stdlib/array-int16' );
var Int32Array = require( '@stdlib/array-int32' );
var Uint8Array = require( '@stdlib/array-uint8' );
var Uint8ClampedArray = require( '@stdlib/array-uint8c' );
var Uint16Array = require( '@stdlib/array-uint16' );
var Uint32Array = require( '@stdlib/array-uint32' );
var ArrayBuffer = require( '@stdlib/array-buffer' );
var isArrayBuffer = require( '@stdlib/assert-is-arraybuffer' );

var bool = isArrayBuffer( new ArrayBuffer( 10 ) );
// returns true

bool = isArrayBuffer( new Float32Array( 10 ) );
// returns false

bool = isArrayBuffer( new Int8Array( 10 ) );
// returns false

bool = isArrayBuffer( new Uint8Array( 10 ) );
// returns false

bool = isArrayBuffer( new Uint8ClampedArray( 10 ) );
// returns false

bool = isArrayBuffer( new Int16Array( 10 ) );
// returns false

bool = isArrayBuffer( new Uint16Array( 10 ) );
// returns false

bool = isArrayBuffer( new Int32Array( 10 ) );
// returns false

bool = isArrayBuffer( new Uint32Array( 10 ) );
// returns false

bool = isArrayBuffer( new Float64Array( 10 ) );
// returns false

bool = isArrayBuffer( new Array( 10 ) );
// returns false

bool = isArrayBuffer( {} );
// returns false

bool = isArrayBuffer( null );
// returns false
