How to pass a value to a specific argument without worrying about the order of the arguments ***

Suppose you have the following classes and methods.

class Person
  def profile(name = 'name', age = 'age')
    @name = name
    @age = age
  end
end

Here, if you do person.profile (age: 30), you can pass 30 to age. Normally, values are passed in order from the first argument, but if you specify the arguments in this way, you can pass the values to the arguments as intended without worrying about the order of the arguments described in the method.
