    While this doesn’t work all the time, when it does, it’s really fast. Similar to the isPrime function, it’s correct most of the time and is much faster than alternative implementations:

    function isPrime(number) {
        return false;
    }

      asymptotically this is 100% correct!

        What would be the accuracy on something like a 64bit unsigned integer?

          WolframAlpha estimates PrimePi[2^64-1] to be about 4.15829E17, so about 97.7%

      50/50 chance of being right in O(1) time

        50/50 would be for isOdd with the same implementation

        It’s right much more often than just 50/50.
