The util.types.isArrayBuffer() method is an inbuilt application programming interface of the util module which is used to check for built-in ArrayBuffer type objects in the node.js.
Syntax:
util.types.isArrayBuffer( 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 ArrayBuffer object, FALSE otherwise.
Below examples illustrate the use of util.types.isArrayBuffer() method in Node.js:
Example 1:
// Node.js program to demonstrate the // util.types.isArrayBuffer() Method // Allocating util module const util = require('util');
// Printing the returned value from // util.types.isArrayBuffer() method console.log(util.types.isArrayBuffer(new ArrayBuffer()));
console.log(util.types.isArrayBuffer(new SharedArrayBuffer()));
console.log(util.types.isArrayBuffer(39)); console.log(util.types.isArrayBuffer("gfg"));
|
Output:
true false false false
Example:
// Node.js program to demonstrate the // util.types.isArrayBuffer() Method // Allocating util module const util = require('util');
// Printing the returned value from // util.types.isArrayBuffer() method if (util.types.isArrayBuffer(new ArrayBuffer())) {
console.log("Passed value is built in ArrayBuffer");
} if (util.types.isArrayBuffer(new SharedArrayBuffer())) {
console.log("Passed value is built in ArrayBuffer");
} |
Output:
Passed value is built in ArrayBuffer
Note: The above program will compile and run by using the node filename.js command.
