Summary
OOP is the backbone of all modern programs. OOP is so ingrained into the IT world that you can’t function as a programmer without an in-depth knowledge of the concept. The days of being able to get away with simply programming machines, in a procedural sense, with ladder logic are quickly fading.
This chapter was simply a soft introduction to OOP. OOP is way more than just organizing your code into function blocks, as many concepts govern the paradigm. Now that we have a grasp of function blocks, methods, properties, and recursion, we can learn to leverage them to reduce redundant code, create cleaner code, and apply actual architecture to programs.
