I want to take the two hashes below and combine them into a new hash or array:



hash1 = 1=>"]", 2=>"", 3=>")", 4=>"(", 5=>"", 6=>"["
hash2 = 1=>"[", 2=>"", 3=>"(", 4=>")", 5=>"", 6=>"]"


I want the result to look something like this:



result = "["=>"]", ""=>"", "("=>")"


or



result = [ ["[","]"], ["",""], ["(",")"] ]


Is there a ruby method that can do this?






ruby hash enumerable

          You could use Hash#transform_keys:



          res = hash1.transform_keys hash2[k] 

          res #=> "["=>"]", ""=>"", "("=>")", ")"=>"(", ""=>"", "]"=>"["

          res.first(3) #=> [["[", "]"], ["", ""], ["(", ")"]]

          Well, another way you can get what you want is by using Hash#deep_merge
          like so:



          res = hash1.deep_merge(hash2) [other_val , this_val] .values
          # => [["[", "]"], ["", ""], ["(", ")"], [")", "("], ["}", "
