Bored yet?

I understand that you might feel a bit frustrated now. We are learning a lot about theory, going through examples, and it isn't exciting at all. I promised fun and we will get there,but I must make sure that you understand the fundamentals of OOP. This knowledge will help us design a cool–looking game that is coded using clean practices. Code can be good and bad, and it can be written in a way that is easily understood by other developers or it might be unmanageable and messy.

By learning how to organize your code, you absorb and use good practices that will help you to be a top developer who is proud of their code. So stay focused! Let's go through the theory and make an awesome game later.

"Any fool can write code that a computer can understand. Good programmers write code that humans can understand."

- Martin Fowler
