function isArrayBuffer
Usage in Deno
```typescript import { isArrayBuffer } from "node:node__util--types.d.ts"; ```
isArrayBuffer(object: unknown): object is ArrayBuffer
Returns `true` if the value is a built-in [`ArrayBuffer`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/ArrayBuffer) instance.
This does _not_ include [`SharedArrayBuffer`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/SharedArrayBuffer) instances. Usually, it is
desirable to test for both; See `util.types.isAnyArrayBuffer()` for that.
```js
util.types.isArrayBuffer(new ArrayBuffer()); // Returns true
util.types.isArrayBuffer(new SharedArrayBuffer()); // Returns false
```
object is ArrayBuffer
