Btw, the following two are equivalent (in JavaScript syntax):

    var a = Math.max(Math.random(), Math.random());
    var b = Math.sqrt(Math.random());

Curious, how come? Does it become a statistical thing?

Well, not sure whether you'd call it statistics. It's a mathematical fact from probability theory. And it doesn't matter how often you sample: the distributions themselves are the same.

I came across that one in the other direction, when trying to work out how to make weighted rendezvous hashing work. See https://en.wikipedia.org/wiki/Rendezvous_hashing
