Node.js util.types.isAnyArrayBuffer() Method Last Updated : 08 Oct, 2021 Comments Improve Suggest changes Like Article Like Report The util.types.isAnyArrayBuffer() method is an inbuilt application programming interface of the util module which is used to perform type checking for any built-in ArrayBuffer objects in the node.js. Syntax: util.types.isAnyArrayBuffer( value ) Parameters: This method accepts single parameter as mentioned above and described below: value: It is a required parameter of any datatype. Return Value: It returns a boolean value i.e. TRUE if the value is a built-in SharedArrayBuffer or ArrayBuffer object, FALSE otherwise. Below examples illustrate the use of util.types.isAnyArrayBuffer() method in Node.js: Example 1: javascript // Node.js program to demonstrate the // util.types.isAnyArrayBuffer() Method // Allocating util module const util = require('util'); // Printing the returned value from // util.types.isAnyArrayBuffer() method console.log(util.types.isAnyArrayBuffer(new ArrayBuffer())); console.log(util.types.isAnyArrayBuffer(new SharedArrayBuffer())); console.log(util.types.isAnyArrayBuffer(12)); console.log(util.types.isAnyArrayBuffer("geeksforgeeks")); Output: true true false false Example 2: javascript // Node.js program to demonstrate the // util.types.isAnyArrayBuffer() Method // Allocating util module const util = require('util'); // Printing the returned value from // util.types.isAnyArrayBuffer() method if (util.types.isAnyArrayBuffer(new ArrayBuffer())) { console.log("Passed value is either built in " + "ArrayBuffer or SharedArrayBuffer "); } if (util.types.isAnyArrayBuffer(new SharedArrayBuffer())) { console.log("Passed value is either built in " + "ArrayBuffer or SharedArrayBuffer "); } Output: Passed value is either built in ArrayBuffer or SharedArrayBuffer Passed value is either built in ArrayBuffer or SharedArrayBuffer Note: The above program will compile and run by using the node filename.js command.
