我想對數組中的散列進行排序

Question

a = [{"name"=> "ted","age"=>1}, 
    {"name"=> "mika","age"=>2}, 
    {"name"=> "bob","age"=>0}] 

如何使用ruby程序對年齡順序（升序）的數組進行排序？

我想成爲以下人員。

a = [{"name"=> "bob","age"=>0}, 
    {"name"=> "ted","age"=>1}, 
    {"name"=> "mika","age"=>2}] 

Answer 1

由於卡里Swoveland在評論說，

a.sort_by { |h| h["age"] } 

我能做的above.thanks。
