The **`ArrayBuffer.isView()`** static method determines whether the
passed value is one of the `ArrayBuffer` views,
such as [typed array objects](/en-US/docs/Web/JavaScript/Reference/Global_Objects/TypedArray)
or a {{jsxref("DataView")}}.

{{InteractiveExample("JavaScript Demo: ArrayBuffer.isView()", "shorter")}}

```js interactive-example
// Create an ArrayBuffer with a size in bytes
const buffer = new ArrayBuffer(16);

console.log(ArrayBuffer.isView(new Int32Array()));
// Expected output: true
```

## Syntax

```js-nolint
ArrayBuffer.isView(value)
```

### Parameters

- `value`
  - : The value to be checked.

### Return value

`true` if the given argument is one of the {{jsxref("ArrayBuffer")}} views;
otherwise, `false`.

## Examples

```js
ArrayBuffer.isView(); // false
ArrayBuffer.isView([]); // false
ArrayBuffer.isView({}); // false
ArrayBuffer.isView(null); // false
ArrayBuffer.isView(undefined); // false
ArrayBuffer.isView(new ArrayBuffer(10)); // false

ArrayBuffer.isView(new Uint8Array()); // true
ArrayBuffer.isView(new Float32Array()); // true
ArrayBuffer.isView(new Int8Array(10).subarray(0, 3)); // true
