Reverse a hash in Ruby

Question

How would I reverse the elements in the hash, keeping the same values and keys, but reversing their order in the hash.

Like so:

{ \"4\" => \"happiness         


        

Answer 1

In Ruby 2.1+ you can combine reverse_each and to_h:

{foo: 1, bar: 2}.reverse_each.to_h
#=> {:bar=>2, :foo=>1}
