A copy-pastable code
Everyday as a software developer you have to invent some abstractions. Simply speaking, you have to decide where to put the new code. After you decide this, you write more code and repeat the process. Sometimes the earlier decisions need to be changed and you refactor the existing code. Now you decide where to put the old code.
I really need a hint. The OOP folks teach us to model the real world. Just look at the problem domain, they say, and you will see where the things belong. It works great until you hit some system-specific pure abstractions and there is no natural metaphor to help you.
Try another approach. Since the initial question is where to put the code, and the refactoring is about moving the code around, why not to make the code itself easily movable? How about making the code copy-paste friendly?
The first idea which comes to your mind is to wrap it in the object. Yes, it might solve the problem. But at what cost? Creating an object means defining the interface (class, protocol, whatever) which creates another entity in the program and eats a part of your brain. Not always a good idea when you are already stuck finding out where’s the best place for just ten lines of code.
When you are trying to solve a problem, do not hurry creating another one. Relax, put the code somewhere where it is easier to move from and make it depend on the nearby code as little as possible. Usually you do so by putting the dependent data in some local variables. You can later transform them into function arguments or object properties.
When you make the code movable, you can (sic!) move it around and isolate more and more over time. Maybe 5 minutes later you will discover you don’t need it at all. Or that it should be simplified and moved in a function. Or that it should have more functionality and become an object. Or that it should be split in two different tasks. All of these questions become much easier to answer when you keep the code simple, stupid, light and isolated just enough. Just enough to copy and paste it.
