isTypedArray

Test if a value is a typed array.

Installation

npm install @stdlib/assert-is-typed-array

Usage

var isTypedArray = require( '@stdlib/assert-is-typed-array' );

isTypedArray( value )

Tests if a value is a typed array.

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

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

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

Examples

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

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

arr = new Uint8Array( 10 );
bool = isTypedArray( arr );
// returns true

arr = new Uint8ClampedArray( 10 );
bool = isTypedArray( arr );
// returns true

arr = new Int16Array( 10 );
bool = isTypedArray( arr );
// returns true

arr = new Uint16Array( 10 );
bool = isTypedArray( arr );
// returns true

arr = new Int32Array( 10 );
bool = isTypedArray( arr );
// returns true

arr = new Uint32Array( 10 );
bool = isTypedArray( arr );
// returns true

arr = new Float32Array( 10 );
bool = isTypedArray( arr );
// returns true

arr = new Float64Array( 10 );
bool = isTypedArray( arr );
// returns true

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

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

bool = isTypedArray( null );
// returns false
