What is the most elegant way to get the value in an array, minimizing a certain class attribute?

Question

Say I have the following class:

class Person
    def initialize(name, age)
        @name = name
        @age = age
    end

    def get_age
        return @age
    end
end

And I have an array of Person objects. Is there a concise, Ruby-like way to get the person with the minimum (or maximum) age? What about sorting them by it?

Answer 1

This will do:

people_array.min_by(&:get_age)
people_array.max_by(&:get_age)
people_array.sort_by(&:get_age)
