Node.js | os.version() Method

Last Updated : 27 May, 2020

The os.version() method is used to identify the version of the kernel of the Operating System. This information is determined by calling uname on POSIX systems and calling RtlGetVersion() or GetVersionExW() on Windows systems.

Syntax:

os.version()

Parameters: This function does not accept any parameters.

Return Value: It returns a string that identifies the kernel version.

Below programs illustrate the os.version() method in Node.js:

Example 1: On POSIX

// Import the os module 
const os = require("os"); 
  
let osVersion = os.version(); 
console.log("OS Version:", osVersion); 

Output:

OS Version: #24~18.04.1-Ubuntu SMP Mon Jul 28 16:12:28 UTC 2019

Example 2: On Windows

// Import the os module 
const os = require("os"); 
  
let osVersion = os.version(); 
console.log("OS Version:", osVersion); 

Output:

OS Version: Windows 10 Enterprise
