I am using Fingerprint2.js (Modern & flexible browser fingerprinting library, a successor to the original fingerprintjs http://valve.github.io/fingerprintjs2/)
I get hash fingerprint when i console.log inside the function. but when i store that result in some variable, it gives 'undifined'

is an asynchronous function (that's why you need to provide a callback to it); Doing return ...

QUESTION
I got a project for school that asked me this stuff:
It is a simple web application for fingerprinting users or visitors. Something similar as this one, except that we don't need to check if fingerprint is unique.
So the app should be modern and should respond to the visitor details of his device (OS, browser, IP address, country, city - this can be done via API /maxmind/... and some other information from device)
Here you can use any framework as you want bootstrap or anything else...
Design should be simple - in front page should have one button in the middle which says: Scan me or whatever, after clicking all results should appear on the page in organized way.
Here is one example of front page: https://fingerprintjs.com/open-source/
The purpose of app is to detect if OS is outdated or browser is not latest version to inform user in some sort of windows. But that we can discuses later.
Can you provide me some sources on how can i start this fingerprint thing, i have good knowledge of web developing html css js back-end and front-end, but implementing fingerprint is first time in my life. THANKS!!!!

Foreach information we have a function for example you can get the fingerprint id like this:
