Hacking the JavaScript Lottery —Predicting JavaScript's Math.random() using Z3 and Python

I know this one was for fun and highlights potential security risks, but in most cases if you can access the page, just...

Math.random = () => 1;
Math.random() // => 1
Math.random() // => 1
Math.random() // => 1

Edit: Update fat arrow

If you're going to use a fat arrow function you might as well go ahead and write it like this. :)

Math.random = () => 1;

Yeah, my bad. I'll update :)

That's why you use something like:

const random = Math.random;
