isArrayBuffer

Checks if the given value is a ArrayBuffer.

This function tests whether the provided value is an instance of ArrayBuffer. It returns true if the value is a ArrayBuffer, and false otherwise.

This function can also serve as a type predicate in TypeScript, narrowing the type of the argument to ArrayBuffer.

Signature

function isArrayBuffer(value: unknown): value is ArrayBuffer;

Parameters

• value (unknown): The value to check if it is a ArrayBuffer.

Returns

(value is ArrayBuffer): true if the value is a ArrayBuffer, false otherwise.

Examples

const value1 = new ArrayBuffer();
const value2 = new Array();
const value3 = new Map();

console.log(isArrayBuffer(value1)); // true
console.log(isArrayBuffer(value2)); // false
console.log(isArrayBuffer(value3)); // false
