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.
