After modelling the card and generating 52 of them. It’s time to create the deck. Let’s shuffle the cards.

The Deck

require_relative 'cards_generator'
require 'securerandom'

class Deck
  def perform
    CardsGenerator
      .new
      .perform
      .shuffle(random: Random.new(SecureRandom.random_number(2**32)))
  end
end

My approach for this is the deck will just be stored in simple array, not object. An object of deck will do, but I want to try something different here.

Deck Manager

With the simple array of shuffled cards (deck), I need another class for managing it.

require 'deck'

class DeckManager
  def initialize
    @deck = Deck.new.perform
  end

  def draw(number: 1)
    @deck.shift(number)
  end
end

This DeckManager class will manage each deck it is generated, including drawing from it.

After this, we can do the following:

deck_manager = DeckManager.new
card = deck_manager.draw
# or
hands = deck_manager.draw(5)

On the next part, we will try to calculate the values of hands.
