Strategy Design Pattern: Code Juggler for Swapping Tricks

Hey coding acrobats! Ever wished your objects could effortlessly switch between different strategies? The Strategy Design Pattern is like having a set of dazzling juggling tricks – it allows you to define a family of algorithms, encapsulate each one, and make them interchangeable. It's the ultimate juggling act for your code, ensuring your objects can gracefully swap their tricks depending on the situation!

Concept:

• Context: Your versatile juggler, ready to perform different tricks.
• Strategy: The dazzling juggling tricks, encapsulating algorithms.
• ConcreteStrategy: Each specific juggling trick, implementing its own algorithm.
• Client: You, the ringmaster, orchestrating this coding circus.

Ruby Juggling Extravaganza:

Let's embark on a Ruby adventure that's as thrilling as a high-flying trapeze act and as entertaining as a clown's routine.

Context:

# Your versatile juggler - the Context
class CodeJuggler
  attr_accessor :current_strategy

  def initialize(strategy)
    @current_strategy = strategy
  end

  def perform_juggling_trick
    @current_strategy.juggle
  end

  def switch_strategy(new_strategy)
    @current_strategy = new_strategy
  end
end

Strategy:

# The dazzling juggling tricks - the Strategy
class JugglingStrategy
  def juggle
    raise NotImplementedError, 'Subclasses must implement the juggle method'
  end
end

ConcreteStrategy:

# Each specific juggling trick - the ConcreteStrategy
class BallJuggling < JugglingStrategy
  def juggle
    puts 'Juggling balls in the air! 🤹‍♂️'
  end
end

class PinJuggling < JugglingStrategy
  def juggle
    puts 'Juggling pins with precision! 🎪'
  end
end

class FireJuggling < JugglingStrategy
  def juggle
    puts 'Juggling fire with daring moves! 🔥🤹‍♂️'
  end
end

Juggling Show Script:

# The ringmaster's script
juggler = CodeJuggler.new(BallJuggling.new)

# The juggling show begins
juggler.perform_juggling_trick

# The juggler switches strategy
juggler.switch_strategy(PinJuggling.new)
juggler.perform_juggling_trick

# Another switch of strategy
juggler.switch_strategy(FireJuggling.new)
juggler.perform_juggling_trick

Why It's a Juggling Act:

The Strategy Design Pattern is like turning your code into a juggling acrobat. It allows objects to switch between different strategies seamlessly, making your system dynamic and adaptable. So, whether you're orchestrating a coding circus or just want your objects to perform tricks, the Strategy Pattern is your ticket to a mesmerizing juggling act. Juggle on, coding acrobats, juggle on! 🎭✨
