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?

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
# => [["[", "]"], ["", ""], ["(", ")"], [")", "("], ["}", "
hash1.merge(hash2) [v1, v2].values
# => [["]", "["], ["", "improve this answer
