Time to take things up a notch!
In this Course, we'll leverage what we learned in Course 1 to really start using what we know. We'll clean up old functions with new classes, learn a practice called dependency injection and organize our objects into something called a container. This is the course that really makes objects useful and sets us up for future stuff (inheritance, interfaces, etc).
So let's get serious:
Service Classes
Organize with private functions
Goodbye arrays, hello BattleResult
Objects passed by Reference
Query from the Database, but using Objects!
Dependency Injection!!!
Creating a Service Container
Do it!
