Without further adu, I introduce Blackjax. It is a simple blackjack game built with JavaScript. I use jQuery to for it's convenience functions and effects.

My focus has been more on the core of the game itself, so there are some things that aren't as polished as others. One example is the form to add players and start the game. Depending on my free-time and pressure from friends I may continue to build upon it.

Challenge for my fellow code geeks

I'd love for you to send me your thoughts on the JavaScript. Let me know how you'd have done it differently. I have refactored the code several times and still am not 100% satisfied with it.

One area that I know needs improvement is handling aces. The logic I am using for the possible double value (1, 11) of an ace is oversimplified and can lead to poor choices by the dealer. For instance, two aces will always equal 2, and never 12.

One suggestion that was given to me is to change how I wrote the objects. Tim Novinger suggested I switch to a JSON Object Literal approach.  The reason I choose to use functions as objects is the ability to create a new instance of objects.

Does refactoring ever stop?

I tried my best to showcase best practices when it came to the design of objects. I spent most of the day yesterday refactoring the code. The last change I made was to separate all the core logic of the game from the display logic. I'm not fully satisfied on how the outcome, but it is much better than before. If you wanted to change from jQuery to mootools it would only effect the display class.

It would be best to refactor the the display code up into smaller objects. The fact that the "BlackjackFrontend" object is responsible for displaying the card just doesn't sit well with me. I'd also like to refactor blackjack specific information from the "Player" object to an one that extends the "Player" to maximize the potential for code reuse.

I think I could refactor this code to death.

Demonstrating the need for testing

This project really taught me the need for unit tests and automated testing. The form of automated testing I used was my dear wife, and I have to thank her for her diligent efforts. Her poor fingers from having to refresh until a specific situation occurred. I still am not sure what would happen if everyone got a blackjack on the deal.

In short, I have placed "Find JavaScript testing framework" on my to-do list.

Overall, I think Blackjax is a solid example of my understanding of JavaScript and a lot more fun that table sorting or form validation. Hopefully it will serve me well.

Anyways, this clip is the outcome of that.

Blue Lights of Heaven

Verse One:
One day while driving a little too fast,
Behind me police lights flashed,
Then sitting there, God reminded me,
Of that sweet day he convicted me.

The Spirit comes to convict from sin,
Point you to the cross where new life begins.
It's that sweet Spirit that gives godly fear,
O' Holy Spirit, linger near.

Chorus:
Blue lights of heaven came after me,
Blue lights of heaven made me bow my knee,
By the law of God and the Spirit's call,
I trusted Christ and surrendered all.

Verse Two:
Trusting in the Lord is the only way, To reach that land of perfect day, We must be born by the Holy Ghost, It's nothing we do, We cannot boast.

By God's word souls are saved,
We praise Him for the grace He gave.
How one day He came to me,
And by God's grace He set me free!
