function types.isArrayBuffer
Usage in Deno
import { types } from "node:util";
isArrayBuffer(object: unknown): object is ArrayBuffer
Returns true if the value is a built-in ArrayBuffer instance.
This does not include SharedArrayBuffer instances. Usually, it is
desirable to test for both; See util.types.isAnyArrayBuffer() for that.
util.types.isArrayBuffer(new ArrayBuffer()); // Returns true util.types.isArrayBuffer(new SharedArrayBuffer()); // Returns false
object is ArrayBuffer
