The util.types.isInt32Array() method of the util module is primarily designed to support the needs of Node.js own Internal APIs. It is used to check whether the passed instance in the method is a built-in Int32Array instance or not.
Syntax:
util.types.isInt32Array( value )
Parameters: This method accepts a single parameter value that holds any value, i.e instance of any module.
Return value: This method returns a Boolean value, i.e true if the passed value is an instance of Int32Array otherwise returns false.
The below examples illustrate the use of util.types.isInt32Array() method in Node.js:
Example 1:
javascript
const util = require( 'util' );
console.log(util.types.isInt32Array( new Map()));
console.log(util.types.isInt32Array( new Int32Array()));
|
Output:
false
true
Example 2:
JavaScript
const util = require( 'util' );
const array1 = new Int32Array(2);
array1[0] = 42;
console.log(util.types.isInt32Array(array1));
const array2 = new Int32Array([21, 31]);
console.log(util.types.isInt32Array(array2));
const array3 = new Int32Array([21, 31]);
const array4 = new Int32Array(array3);
console.log(util.types.isInt32Array(array4));
const array5 = new Int16Array(2);
array5[0] = 10;
console.log(util.types.isInt32Array(array5));
