Package Exports

  • @a-2-c-2-anpm/laboriosam-odit-beatae
  • @a-2-c-2-anpm/laboriosam-odit-beatae/index.js

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 (@a-2-c-2-anpm/laboriosam-odit-beatae) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Is this value a JS SharedArrayBuffer? This module works cross-realm/iframe, does not depend on instanceof or mutable properties, and despite ES6 Symbol.toStringTag.

Example

var assert = require('assert');
var isSharedArrayBuffer = require('@a-2-c-2-anpm/laboriosam-odit-beatae');

assert(!isSharedArrayBuffer(function () {}));
assert(!isSharedArrayBuffer(null));
assert(!isSharedArrayBuffer(function* () { yield 42; return Infinity; });
assert(!isSharedArrayBuffer(Symbol('foo')));
assert(!isSharedArrayBuffer(1n));
assert(!isSharedArrayBuffer(Object(1n)));

assert(!isSharedArrayBuffer(new Set()));
assert(!isSharedArrayBuffer(new WeakSet()));
assert(!isSharedArrayBuffer(new Map()));
assert(!isSharedArrayBuffer(new WeakMap()));
assert(!isSharedArrayBuffer(new WeakRef({})));
assert(!isSharedArrayBuffer(new FinalizationRegistry(() => {})));
assert(!isSharedArrayBuffer(new ArrayBuffer()));

assert(isSharedArrayBuffer(new SharedArrayBuffer()));

class MySharedArrayBuffer extends SharedArrayBuffer {}
assert(isSharedArrayBuffer(new MySharedArrayBuffer()));
