Welcome, JavaScript Interview #8: Program to Find Prime or Composite Numbers in JavaScript.

What is A prime number?
A Prime Number is a whole number with exactly two integral divisors, 1 and itself. The number 1 is not a prime, since it has only one divisor.

What is a Composite Number?
A composite number is a whole number with more than two integral divisors. So all whole numbers (except 0 and 1 ) are either prime or composite.
