If you want to iterate over each nested hash - it totally depends on the
depth of the hash and the kind of view you're trying to build using it. If
you dont have knowledge about the other keys that come in the hash, use
this pattern.
h = { "a" => 100, "b" => 200 }h.each {|key, value| puts "#{key} is #{value}" }
