Codewars Challenge: Stop gninnipS My sdroW!

spinwords.rb

#Write a function that takes in a string of one or more words, and Drop one or more filereturns the same string, but with all
#five or more letter words reversed (Just like the name of this Kata). 
#Strings passed in will consist of only letters and spaces. 
#Spaces will be included only when more than one word is present.

#Examples:

#spinWords( "Hey fellow warriors" ) => returns "Hey wollef sroirraw" 
#spinWords( "This is a test") => returns "This is a test" 
#spinWords( "This is another test" )=> returns "This is rehtona test"

#My Solution

def spinWords(string)
  words = string.split
  words.map do |word| 
    word.reverse! if word.length >= 5 
  end
  words.join(" ")
end
