isArrayBuffer#

Check if the given value is an ArrayBuffer.

Usage Scenarios#

• Data Validation: When processing binary data, you need to ensure that a certain value is an ArrayBuffer before performing subsequent operations, such as data parsing or serialization.
• Function Parameter Validation: In a function, when an ArrayBuffer is expected as a parameter, you can use the isArrayBuffer method to verify the parameter type, avoiding errors caused by passing non-ArrayBuffer values.
• Conditional Judgment: Execute different logic based on whether a value is an ArrayBuffer.

Examples#

import { isArrayBuffer } from 'funtool';

isArrayBuffer(new ArrayBuffer(8)); // ✅ true
isArrayBuffer([]); // ❌ false

Signature#

function isArrayBuffer(v: any): v is ArrayBuffer

Parameters#

• v (any): The value to test if it is an ArrayBuffer.

Returns#

• (v is ArrayBuffer): Returns true if the value is an ArrayBuffer, otherwise returns false.
