Oops, try again.
It looks like you didn't correctly use the conditional assignment operator in your code. Check the Hint if you need help!
can you check line 14. prime_array ||=  #if prime_array.nil?
$VERBOSE = nil # We'll explain this at the end of the lesson. require 'prime' # This is a module. We'll cover these soon! def first_n_primes(n) unless n.is_a? Integer return "n must be an integer." end if n <= 0 return "n must be greater than 0." end prime_array ||=  #if prime_array.nil? prime = Prime.new for num in (1..n) prime_array.push(prime.next) end return prime_array end
