## 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()));

```
