## PRIME NUMBERS
A Prime number is a number that is not evenly divisible by another number except 1 and itself.
To test whether a number is Prime, you only need to test as far as the square root of that number. This
To test whether a number is Prime, you only need to test as far as the **square root** of that number. This
is advisable for optimization and testing large numbers.
## STEP ONE
### STEP ONE
1. Write a function called `isPrime` that will test whether a number is Prime. The function will return true if Prime, false if not.
## STEP TWO (Bonus)
### STEP TWO
2. Write another function called `primes` that will print an array of Primes up to an arbitrary limit. For example, if you invoke your function with `primes(100)`, it will print all the Prime numbers up to and including 100.
This function can call on the previous `isPrime` function.
