ArrayBuffer.isView()
Baseline
Widely available
This feature is well established and works across many devices and browser versions. It’s been available across browsers since July 2015.

static method determines whether the

views,
such as typed array objects
or a DataView
.
Try it
// Create an ArrayBuffer with a size in bytes
const buffer = new ArrayBuffer(16);
console.log(ArrayBuffer.isView(new Int32Array()));
// Expected output: true
Syntax
js
ArrayBuffer.isView(value)
Parameters
value
-
The value to be checked.
Return value
true
if the given argument is one of the ArrayBuffer
views;
otherwise, false
.
Examples
