Generate v4 UUID from Specific Javascript

Question

My boss has asked me to follow this guide for generating a UUID from this link: https://intercom.help/revcontent2/en/articles/3436818-html-ads-generate-your-own-uuids

But I have no clue how to do it. I tried adding it to a file called test.js and opening it on Windows. I tried installing node.js and opening it through command prompt. I pasted it into a fiddle. But no success.

I just need a UUID generated from this code:

function uuid() {    
    var uuid = "", i, random;    

    for (i = 0; i < 32; i++) {      
        random = Math.random() * 16 | 0;        

        if (i == 8 || i == 12 || i == 16 || i == 20) {        
            uuid += "-";      
        }

        uuid += (i == 12 ? 4 : (i == 16 ? (random & 3 | 8) : random)).toString(16);    
     }   

     return uuid;  
}

Can someone please help me? Or just generate a code tell me what it is?

Thank you :)

First of all, please have a look and search for other threads before creating a new question. Like this one.

This MDN article is also a very good start.

Secondly, for things like this (executing a specific JS code), you can:

open your browser
go to Tools -> Developer Menu (or use specific Windows/Unix shortcuts to get here)
go to Console
paste your code above
then call your method, in your case, call uuid()
and voila! You can see the results!

Sample uuids generated by your code:
