Object Oriented Programming

From my personal experience in corporations and startups alike, using Javascript OOP on the frontend usually creates an unintentional mess of polymorphism. OOP is great, but it has it's uses, just like functional programming.
My understanding is, that you web development can greatly benefit from using OO principles. But currently I do not see much support for this idea.
Thank you for sharing your thoughts! I appreciate your perspective. I kind of agree with you that there is not much support for OOP on the frontend in the web dev world. However, there's always Angular and the older version of React, which implement OOP principles very well. Even on the backend, I have been able to write clean, modular code using Node.js.
Maybe you like to try out DML. I wrote this library to build fully reactive frontends.
DML does not force to use OOP, but it creates some prerequisites to write OOP code:
DOM elements are already objects, so there is not much to do for for the standard HTML-elements. But with DML, you can extend this concept to self generated objects, that are generated the same way as standard elements. Think of an image carousel, a complex input element or any UI-element, that contains more than one DOM element. On the DML homepage (which was generated using DML), there is this funny jell yfish-menue. This can be generated using one single line of code, all interactions fully encapsulated the a class.
The DML homepage is pretty fast, though the code is not much optimizes (no bundler used). Please do your own performance checks to see, if this could be an option for your projects. I´m just about to release a new version, but the core will be very similar, so it´s worth a try.
Thank you for the in-depth explanation. Your initial comment is much clearer to me now. I will definitely check out this library.
do you think oop is enough?
Hey Helina, thank you for your comment! Could you please elaborate on your question? Are you referring to its suitability for specific tasks, or do you have a particular concern about its limitations?
what im mean is that there are other programming paradigms, but the oop is the most famous so my question is, do i have to learn other paradigms besides oop or is it enough
In my opinion, once you are comfortable with OOP, you can start looking into functional programming, but it is not a necessity; however, it is always good to know. I have read that many features in the React ecosystem, such as state management in Redux, leverage functional programming principles.
If you look at the 2004 paper The Structure and Interpretation of the Computer Science Curriculum the educators involved found that students typically had an easier time starting with functional programming and then transitioning to class-based object-oriented programming.
Given my personal experience I have no trouble accepting that, given the amount of unlearning I had to do when moving from OO to FP (and beyond). This group of researchers eventually had to concede that a scheme-like language isn't ideal for all students which is why they created Pyret. And in their most recent efforts they don't focus on either FP or OO but on data: A Data-Centric Introduction to Computing (without falling back into structured programming; they also elaborate where Python falls short for their purposes).
James Coplien jokes that JavaScript is the only object-oriented language because the code actually manipulates objects directly while all the mainstream class-oriented languages only create objects via classes. In class-oriented languages an instance has a lifetime membership with its class and in most cases that membership significantly impacts its behaviour.
In JavaScript an object tracks its
constructorbut other than that aclassis just a template for creating objects. After creation an individual object can be augmented in any number of ways (Monkey Patching) blurring its relationship to the creating class.From that view the term
objectis unfortunate. “Tables are the main (in fact, the only) data structuring mechanism in Lua, and a powerful one.”.I think I finally “get” JS objects

Once plain JavaScript objects are simply viewed as key-value data containers and “functions are objects” is accepted as a convenience feature the Function-Oriented nature of JS emerges, especially when one considers its Scheme-y past.
Granted JavaScript is said to support object-oriented, imperative, and declarative (e.g. functional programming) styles but there are trade-offs to be considered.
The notion of a performance budget is something you would typically expect with embedded products, not necessarily something application-level developers would have to concern themselves with. Given the engineering behind products like TurboFan JavaScript is already faster than it has any right to be but it can't compare to native (though Static Hermes may change that).
Classes also interfere with tree-shaking. For this reason libraries like RxJS which started out as class-heavy ports of the C#/Java originals, now minimize their use of classes and limit the methods on those that remain to the absolute, bare minimum.
Keep in mind that today's mobile devices vary wildly in their performance characteristics and capabilities; so while the flagship devices keep improving, the average, commodity devices really aren't.
When faced with a similar reality with regards to gaming consoles in 2009 the gaming industry started moving from OO to Data-Oriented Design and embracing the Entities, Components, Systems (ECS) approach.
Note that often the contention that imperative or OO programming is “easier” is a result of the familiarity heuristic; subjectively we perceive whatever we already know (e.g. learned first) as “easier”—just because something is different doesn't mean it's difficult.
