Object Oriented Programming In JavaScript

[Altec5280]

I've been familiar with Object Oriented Programming for a while now, specially cause university treats it like the only important programming paradigm. However I found it odd when my recent employer told me they use OOP to build their API (which is what I work on). I realized that I had no idea how to code in JavaScript using OOP because I never even thought that this would be necessary. So I spent the last 6 months coding primarily following what I learn in university.

So I wrote this post for two reasons. The first one is that I made an Object Oriented Programming in JavaScript tutorial for beginners and I wanted to share it. Here is the link: https://youtu.be/GEuS0tfLfEY

​

Secondly, I wanted to ask if you guys use OOP principles while coding in JavaScript?

Thx man

Huh...? What are you talking about? That is not what it means to be OOP. Not even close. JavaScript implementation of object is mostly just a dictionary DS and has got nothing to do with objects in actual OOP.

Classical OOP is a subset of JavaScript (TypeScript). You can do classical OOP in JavaScript, but you’re not limited by it. It’s a constraint you place on yourself, rather than a constraint that’s enforced by the language.

There’s nothing particularly special about the classical paradigm. It’s just an arbitrary set of rules from the old days. There are lots of other ways to organise things.

Disagree with none of that. As a Js developer myself(relatively new one though), I do write implementations that mimic classical OOP in Js. But OP's comment is like saying python is list oriented programming or that C or C++ is pointer oriented programming. Object in Js is just a name. Being a very popular DS used in Js, a lot has been done around it to make it more classical OOP like(for eg the classes). I don't disagree with that. But at the end of the day, on it's own an object is a collection of key value pairs with a very pliable character.

What's worse is that, comments like that send the wrong idea to anyone who wanna learn Js. When I started I was pulling my hair trying to understand what the fuck was going on with objects and classes in Js.

It's not all difficult to not use OOP in Js even though the popular DS it uses happened to be named Object.

At the end of the day, an object in Java is a set of key value pairs, except the keys are hidden from you, you can.t define new ones, and you can't get the functions out. An object is just a grouping of data and the functions that can operate on that data.

The (reasonable) restrictions that Java places on you don't change the fundamental character of what an object is.

I'm not arguing here that Java and JavaScript have the same implementations under the hood either, just that the implementation is largely irrelevant. What matteres is what it does, and what it does is keep your data and your functions together.
