Is there a way of detecting a bug that only happens with a specific person/ hardware within a React application? Cause the bug is undetectable and never happens with tests and etc, only happens with a specific client from my company.
Any clue on how to debug those kind of hidden/undetectable bugs ?

you can add something like https://sentry.io/ to capture errors in production, and get the stack trace of the error, and details like browser version, etc

Is it possible to detect the time since a device was last booted in client-side JavaScript?
In client-side javascript; NO.
The OS level details are not exposed to the javascript run-time in browsers
But if by client-side you mean an android application running javascript in WebView, there may be a plugin to extract the info

I've seen a lot of posts with this question. But apparently, they're all outdated. There's any chance to disable that execution nowadays?
EDIT: Chrome Console, I'm trying to deny any javascript execution that any user writes on the console.
Per your comment:

This request is impossible. Users can execute whatever JavaScript they would like. They can also choose to disable any or all of your JavaScript.

I am starting a new Android app, and I would like to know what should be the best server-side stack that I could use.
I heard some about MeanIO, MeanJS, Cleverstack, Generator Angular Fullstack.
Which of these suggestions should be the best? Is there another one that is not on the list that would be even more interesting?
If I am correct in saying it depends in what you're doing and trying to focus on. If you wish to also build a web-based front-end it's probably necessary to include AngularJS. If you aren't planning on doing that you could probably cut out the need for Angular.
I imagine the MEAN stack (https://github.com/meanjs/mean) would be enough for your Node.JS server. I doubt you will need to use Angular for an android app so you will be more focused upon the Express+Node+Mongodb portions.

As an example, let's assume I want to prevent users from using auto-clickers. Is it possible, and are there accepted best practices when doing this?
Nope, it is not possible. Someone can always turn off JavaScript, modify it, run their own JS-code, etc, etc. JavaScript should never ever be used for security reasons.
However, for AJAX-requests you could implement a minimum interval server-side (like on Stack Overflow).
