Package Exports

@stdlib/assert-is-sharedarraybuffer

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (@stdlib/assert-is-sharedarraybuffer) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

isSharedArrayBuffer

Test if a value is a SharedArrayBuffer.

Installation

npm install @stdlib/assert-is-sharedarraybuffer

Usage

var isSharedArrayBuffer = require( '@stdlib/assert-is-sharedarraybuffer' );

isSharedArrayBuffer( value )

Tests if a value is a SharedArrayBuffer.

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

var bool;
try {
    bool = isSharedArrayBuffer( new SharedArrayBuffer( 10 ) );
    // returns true
} catch ( err ) {
    console.log( 'Environment does not support SharedArrayBuffers.' );
}

bool = isSharedArrayBuffer( [] );
// 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' );
