I get angry every fucking time when I see such method signature:

method(int, int, int, string, string, string, string)

Sounds scary, doesn't it?

Nah. That's the reason our IDEs are so complex. So, I change this and put proper data value/struct class instead, just to make this much readable and understandable for everyone.

And, every time there is a fella that asks this utterly stupid question:

What about performance impact?

Aaaaaaaaaaaaaa fuckyutitititiigig

And. I. Have. To. Run. Performance. Tests.

Because noone understands performance and computers so I have to prove there is nothing to worry about.

I know when I will go somewhere else I will have to again prove some fuckwit that web applications are so complex already, so adding a new data structure doesn't impact its performance.

    Performance impact over something like that? If that sort of thing is really an issue, then you'd be best doing the whole thing in assembly.

    @AlmondSauce my thoughts exactly. I have been in such situation a couple of times, and it sounds so ridiculous but still you have to prove it doesn't mean anything.

    You're right, it's easy to fall into that trap.

    The best code I write is usually the second or third fresh attempt. It lets me reconsider everything without the assumptions and limitations of the old code, I understand better where the ugly parts of the problem pop up and the uninteresting parts can often be copy-pasted from the previous iteration with minor modifications.

    Keep it simple and flexible. In many cases the compiler/runtime will completely remove a lot of abstractions anyway and can detect possible optimisations in a couple milliseconds. If you think more than a few milliseconds about the number or structure of function arguments you're probably thinking about the wrong thing.

    What performance impact? You're allocating a class. Depending on the language now you're probably passing a reference to the object rather than copying all the primitives.

    And usability >>> performance most of the time.

    @rolexpo all cases were in Java and if you introduce such structure there is a new object, hence additional memory has to be allocated. Nothing significant though. It's all bullshit.

    Simple. use reflection. Everywhere. For everything.
    no more performance, no more problem.

    I see I see. What in saying is that if you make a class, it will allocate this in the heap. And now you're modifying 1 memory object instead pass by value multiple times unless you're making new objects and what not.

    Anyways, the person who brought up performance is an idiot. A method that had 7 variables definitely need a class.

    @magicMirror hmmmmmmmmmmmmmm

    Sounds like a plan for the next battle!

    Guilty! I used to forward declare my functions like that in C (just because I could).

    If you have that many parameters you have a design issue not a clean code issue. Yes defining an extra pojo is a simple fix but doesn't fix underlying problems.

    I would ask those same questions to make sure you benchmark your changes (and continue to do so on your own), not because I think it’s a performance concern. Also, performance still matters, especially in some areas. For example, in bulk processing at work, even a small change can add half an hour to the processing time.

    Usually there is no performance impact at all unless there is some bs cost in dereferencing a value or very costly object instantiation going on. Even in PHP the object is passed as a ref (unless it's values are modified and you probably shouldn't).
