// os.type() method 
   
// Allocating os module
const os = require('os');

// Printing os.type() value
console.log(os.type());

Output:

Windows_NT

Example 2:

javascript

// Node.js program to demonstrate the    
// os.type() method 
   
// Allocating os module
const os = require('os');

// Printing os.type() value
var type = os.type();
switch(type) {
    case 'Darwin':
        console.log("MacOS");
        break;
    case 'Linux': 
        console.log("Linux operating system");
        break;
    case 'Windows_NT':
        console.log("windows operating system");
        break;    
    default: 
        console.log("other operating system");
}
