What is Node.js util.types.isInt16Array() Method?

In this article, we will learn Node.js util.types.isInt16Array() Method,This free Node.js tutorial for complete beginners will help you learn Node.js from scratch.

Node.js util.types.isInt16Array() Method

Node.js util.types.isFloat64Array() Method

Node.js util.types.isInt8Array() Method

The util.types.isInt16Array() method is an inbuilt application programming interface of the util module which is used to check the type for Int16Array in the node.js.

Syntax:

util.types.isInt16Array( value )

Parameters: This method accepts a single parameter as mentioned above and described below.

value: It is a required parameter that holds any data type.

Return Value: It returns a boolean value, TRUE if the value is an Int16Array object, FALSE otherwise.

Example 1: Below examples illustrate the use of util.types.isInt16Array() method in Node.js

javascript

// Node.js program to demonstrate the
// util.types.isInt16Array() Method
 
// Allocating util module
const util = require('util');
 
// Value to be passed as parameter of
// util.types.isInt16Array() method
let v1 = new BigInt64Array();
let v2 = new BigUint64Array();
let v3 = new Float32Array();
let v4 = new Int8Array();
let v5 = new Int16Array();
 
// Printing the returned value from
// util.types.isInt16Array() method
console.log(util.types.isInt16Array(v1));
console.log(util.types.isInt16Array(v2));
console.log(util.types.isInt16Array(v3));
console.log(util.types.isInt16Array(v4));
console.log(util.types.isInt16Array(v5));

Output:

false
false
false
false
true

Example 2: In this example, we illustrate the use of util.types.isInt16Array() method in Node.js

javascript

// Node.js program to demonstrate the
// util.types.isInt16Array() Method
 
// Allocating util module
const util = require('util');
 
// Value to be passed as parameter of
// util.types.isInt16Array() method
let v1 = new Int8Array();
let v2 = new Int16Array();
 
// Calling util.types.isInt16Array() method
if (util.types.isInt16Array(v1))
    console.log("The passed value is a Int16Array.");
else
    console.log("The passed value is not a Int16Array");
 
if (util.types.isInt16Array(v2))
    console.log("The passed value is a Int16Array.");
else
    console.log("The passed value is not a Int16Array");

Output:

The passed value is not a Int16Array.
The passed value is a Int16Array

Note: The above program will compile and run by using the node filename.js command.
