RubyのHashをsortするのにハマった

Last updated at Posted at 2013-12-17

RubyのHashをsortするのにハマった

#!/usr/bin/env ruby

h = {"foo" => 10, "bar" => 30, "baz" => 50}

p h
# {"foo"=>10, "bar"=>30, "baz"=>50}

p h.sort
# [["bar", 30], ["baz", 50], ["foo", 10]]

p Hash[h.sort]
# {"bar"=>30, "baz"=>50, "foo"=>10}

Hashを明示的にしたらイケた。もっと良い方法ありそう。
