Blackjack class

Objectives

Learning Objectives

• Understand @instance_variables and an object's internal state
• Better understand data flow, variable scoping, and method resolution (where does variable_name come from?)
• Practice the implementation side of TDD

  Performance Objectives

After completing this assignment, you be able to effectively use

• Classes to structure and organize logic and data
• initialize and method definition to implement classes to a spec
• require to split projects into multiple files

  Details

  Deliverables

A link to a repo containing:

• The blackjack_spec.rb file presented in class, unchanged.
• A blackjack.rb file.
• Any other files required for the specs to pass.

  Requirements

• Running ruby blackjack_spec.rb should show all tests passing.

  Normal Mode

Get the specs passing, implementing the classes in order.

Hard Mode

• Write a playable blackjack game that uses the classes previously designed.
• Write tests for any other classes you'd like to use (preferably do this first, if you have a sense what those objects should be)

I believe the tests all run (and I added a few to make sure that my Aces were giving the correct score). I got start on a first attempt at the game blackjack but didn't make it very far. Also, I need to rethink how my "to_s" method for the Hand class works. It passes the test but in practice is malfunctioning. I'll ask you about it tomorrow.

Cool, definitely looking good :+1: A few nitpicks -

• It's not wrong, but it does seem a bit strange for the value method to change the @value variable depending on the @value variable.
• Why not use each again here?
• This slice seems a little weird. It seems easier to me to convert the cards to strings individually, and then just use join(', ').

I'm not sure how playable the hard mode is (or how much you want it to be), but consider adding betting, money, rounds, and cumulative scores if you want to keep going further.
