          Alright, I'm no mathematician, but I think this is a bit too cute. Particularly: & 15 which reduces an 8 bit value to a MAXIMUM 4 bit value. I think this function works to create UUIDs that match a format, but possibly (??) with drastically reduced randomness.

        Caveat: I really don't know. The RFC 4122 spec isn't something I feel like studying at the moment, and my bitmath is awful. This just has a feel about it...

      And by the way: golfing algorithms like this grinds my _fucking_ gears. There are FOUR math operations in a single expression with exactly zero parentheses. Nobody cares how many bytes your code is. No one. Are you generating UUIDs on an embedded device in JS? No. Stop it.

    (No one cares how many bytes your authored code is. Your executed code is a different story.)

      By the way, it's possible this washes in the end: A "better" algorithm would generate the same 8 bit random value 16 times (which I believe the spec demands). However, this algorithm generates the 8 bit value truncated to 4 bits (via & 15) THIRTY ONE times... So maybe a wash.
