Node.js util.types.isAnyArrayBuffer() Method

  • Last Updated : 08 Oct, 2021

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:




// 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:




// 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.
