How to count duplicates in Ruby Arrays

Question

How do you count duplicates in a ruby array?

For example, if my array had three a\'s, how could I count that

Answer 1

Its Easy:

words = ["aa","bb","cc","bb","bb","cc"]

One line simple solution is:

words.each_with_object(Hash.new(0)) { |word,counts| counts[word] += 1 }

It works for me.

Thanks!!
