Long Solution (my first solution)

def getVowelCount(str)
  vowels = ["a", "e", "i", "o", "u"]
  count = 0
  str.downcase.split('').each do |char|
    vowels.each do |vowel|
      char == vowel ? count += 1 : count += 0
    end
  end 
  count
end

Short Solution (my refactored solution)

def getVowelCount(str)
  str.downcase.count("aeiou")
end

It would be interesting to know if str.count("aeiouAEIOU") was faster, or if reordering the letters to try to get the most likely match first was better – e.g. str.count("eiaouEIAOU")
