In order to create a new player type, say, a super computer, You'd create a class SuperComputer extends Player and will only have to implement the selectColumn method.
To create different sets of player combinations, say, human vs super computer, you'd create a class HumanVsSuperComputer extends Game and will have to implement both abstract methods launchPlayer1 and launchPlayer2 where you will create and return new instances of HumanPlayer and SuperComputerPlayer respectively. You will also have to create an instance of your new HumanVsSuperComputer in main.js.
- I use abstract functions in this implementation. Javascript doesn't support abstract functions and classes yet. There are some hacks and workarounds that are nowhere native, so I decided to leave it as it is, as the purpose is to demonstrate OO design, using abstract functions IMHO is very elegant, and I didn't want to switch my goto language.
- Efficiency is not top notch. There are full board scans for each direction whereas I could implement a more local scan in response to a new disk location, but since efficiency wasn't a factor for this exercise, I decided to leave it as it is.
- As much as I tried, never actually got to see the "Game Over" scenario where no player wins, in action.
