Structure and Components of a Class Statement

It seems obvious, but note that you must define a class before you use it.

When you create a class, it establishes its own namespace and all its own local variables (except global definitions) exist only inside that namespace. They do not interact with other variables of the same name outside it. This leads us to one very important “feature” of classes that you need to know. If you use the same word to designate some specific value both inside and outside the class blueprint, the instance value will take precedence when you try to use that value.

Mixing static, class and abstract methods

When building classes and inheritances, the time will come where you will have to mix all these methods decorators. So here's some tips about it.

Keep in mind that declaring a method as being abstract, doesn't freeze the prototype of that method. That means that it must be implemented, but it can be implemented with any argument list.
