isArrayBufferView

Test if a value is an ArrayBuffer view.

Installation

npm install @stdlib/assert-is-arraybuffer-view

Usage

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

isArrayBufferView( value )

Tests if a value is an ArrayBuffer view such as a DataView or TypedArray.

var Int8Array = require( '@stdlib/array-int8' );
var ArrayBuffer = require( '@stdlib/array-buffer' );

var bool = isArrayBufferView( new Int8Array( 10 ) );
// returns true

bool = isArrayBufferView( new ArrayBuffer( 10 ) );
// 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 Uint16Array = require( '@stdlib/array-uint16' );
var ArrayBuffer = require( '@stdlib/array-buffer' );
var isArrayBufferView = require( '@stdlib/assert-is-arraybuffer-view' );

var bool = isArrayBufferView( new Int8Array( 10 ) );
// returns true

bool = isArrayBufferView( new Int16Array( 10 ) );
// returns true

bool = isArrayBufferView( new Uint16Array( 10 ) );
// returns true

bool = isArrayBufferView( new Int32Array( 10 ) );
// returns true

bool = isArrayBufferView( new Float64Array( 10 ) );
// returns true

bool = isArrayBufferView( new Float32Array( 10 ) );
// returns true

bool = isArrayBufferView( new ArrayBuffer( 10 ) );
// returns false

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

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

bool = isArrayBufferView( null );
// returns false

Notice

This package is part of stdlib, a standard library for JavaScript and Node.js, with an emphasis on numerical and scientific computing. The library provides a collection of robust, high performance libraries for mathematics, statistics, streams, utilities, and more.
