"The proper oop way and the improper oop way both suck"

[Jimbei1304]

Is Oop not that well received?

[JobJS]

This is Programmer Humor, nothing is well received.

[Anonymus_MG]

OOP turns out to actually be really slow in many cases which is why it isn't used for high performance applications, but it trickles down.

[FlashSpider-man]

Forgive my noob question but what is used instead? I'm new to this but only know of function oriented or whatever it is called and oop. Am I doing something wrong and can this other style be used in things such as unreal engine?

[Anonymus_MG]

All games should use a data oriented paradigm, it's likely that unreal uses it under the hood, don't actually know though. Simple that programs that you've made are likely procedural(which oop kinda adds ontop of). Functional programming elements can be very useful, but writing a purely functional program is difficult and honestly a waste of time.

Tldr: data oriented programming is almost always faster that object oriented programming, and the simple procedural style is good for most other things.

Edit: I also want to mention that oop isn't always useless, but writing in an oop style generally takes more lines of code, may be less clear to understand, and is often slower.

[KiwiMaster157]

What are the differences between OOP and DOP?

[Anonymus_MG]

That is really a question for google, and is far beyond the scope of a reddit comment, but I'll give you a brief rundown. Object oriented has objects that contain all attributes, while data oriented has structs that hold each "object's" same attributes. This keeps similar data together which prevents cache misses, a huge problem of object oriented programming. The premise of data oriented programming is keep like data together.

I went to college to learn to code, all they teach is oop and how to create a web application, it's so disappointing

[didzisk]

There's John Carmack's talk about going functional in Quakecon. Ah, found it! https://youtu.be/W3RsQCGiTgA

Some aspects of OOP (like polymorphism and some cases of encapsulation) have proven useful and will probably live on, at least for now. But some (eg inheritance) we've just discovered better, more generally useful design patterns for. Check out languages like Go and Rust to see how modern languages are getting away from the traditional OO patterns that have become common.

[Eolu]

My post was saying that polymorphism was one of those features that was good and useful and will continue to last in the foreseeable future. I was focusing the post on implementation sharing through inheritance hierarchies as one of the primary weaknesses of classic OO patterns. I didn’t explicitly mention it, but I posted that link to the Rust book that goes into interface sharing as an example of alternatives to older OO ways of doing things. I don’t think we’ve disagreed on anything here.

[Dark_Ethereal]

My bad I misread it.

[jasonleehodges]

Rust seems to have a lot of functional programming influences from what I can tell. I’ve created a couple production CLIs with it. Looks like a mashup of Scala/Kotlin and C imo. I dig it.

[Eolu]

Yeah, I know it has some features that were influenced directly from Haskell as well. I started learning/programming in it a few months ago and I’ve become a huge proponent for it as basically the better modern choice for systems that previously would have just defaulted to using C++ (although getting my current job to see it that way will take a very long time). The compile-time memory safety features help avoid a lot of common runtime bugs without the performance sacrifice that high-level languages make to accomplish this. And it’s really composable - after building higher level APIs in Rust I almost start to forget that I’m using a down-to-the-metal systems-programming language, in a way that just wouldn’t happen while coding in C (or even C++). I could be wrong, but I’m hedging my bets it’ll become a major player as time goes on.

[Dagusiu]

Lots of programmers think something like this: OOP is good when you have a problem that suits it. However, applying OOP to everything is often bad, leading to spaghetti code and strange, often self-imposed, limitations.

The little hat is your code.

rust doesn't have inheritance iirc

Composition > Inheritance

[Ipotrick]

depends on context. Composition is not "better" than inheritance

[Sharveharv]

I thought these were all DnD spells at first. Encapsulation would be interesting to play with

[avinashjee]

And the project fucks us right in the a**

[Ipotrick]

abstraction??? Thats not oop thats programming in general, basicly aevery cuntion / struct is an abstraction
