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
|
||
|
|
|
||
|
|
```js
|
||
|
|
var assert = require('assert');
|
||
|
|
var isSharedArrayBuffer = require('is-shared-array-buffer');
|
||
|
|
|
||
|
|
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()));
|
||
|
|
```
|
||
|
|
|

|
