Of course, you can pass strings instead of numbers if you'd like:primality('13'); // => truePrimality can even do arrays. If any of the values in an array are not prime, false is returned.primality([17, 19, 23]); // => true primality([17, 20, 23]); // => false...

In addition to limit test to numbers less or equal to square root of the range up limit (sqrt(n)), you could step by 2 to only test odd numbers appart two (if not divisible by 2, necessarly not divisable by all even numbers), and use of binary and instead of modulo for tes...
This chapter describes the prime numbers. Any number > 1 which has no natural divisors except itself and 1 is called a prime number, or a prime. A necessary and sufficient condition for a natural number> 1 to be a prime is thatshould not be the product of two natural numbers less than...
