Node.js util.types.isInt16Array() Method

  • Last Updated : 08 Oct, 2021

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

Syntax:

util.types.isInt16Array( value )

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

  • value: It is a required parameter that holds any datatype.

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

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

Example 1:




// 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
var v1 = new BigInt64Array();
var v2 = new BigUint64Array();
var v3 = new Float32Array();
var v4 = new Int8Array();
var 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:




// 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
var v1 = new Int8Array();
var 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.
