JavaScript OOPS: Classes, Objects, Inheritance

Day 72 – Object Oriented Programming (OOP) in JavaScript Today I explored one of the most powerful programming paradigms — Object Oriented Programming (OOP) in JavaScript. OOP helps us structure code using real-world concepts like objects, classes, inheritance, and methods. 🔹 Creating a Class in JavaScript class Sample { constructor(name, place){ this.n = name; this.p = place; } findAvg(chemistry, physics, maths){ return `${this.n} from ${this.p} got ${(chemistry + physics + maths) / 3}`; } } const obj = new Sample("Nasil", "Marutha"); console.log(obj.findAvg(55, 65, 74)); ✅ Key Learnings: class keyword is used to define a blueprint. constructor() runs automatically when an object is created. this refers to the current object. Methods are called using the object (obj.method()). 🔹 Inheritance in JavaScript Inheritance allows a child class to access properties and methods of a parent class. class Car { constructor(brand){ this.car_name = brand; } present(){ return `I have a ${this.car_name}`; } } class Model extends Car { constructor(brand, model){ super(brand); this.mod = model; } show(){ return `${this.present()}, the model is ${this.mod}`; } } const obj = new Model("BMW", "X6"); console.log(obj.show()); ✅ Key Concepts: extends → used for inheritance super() → calls the parent class constructor Child class can use both parent and its own methods Method overriding happens if child defines same method 🔹 Important Differences (JS vs Python Understanding) JavaScript uses constructor() Python uses __init__() JavaScript uses extends Python uses Child(Parent) JavaScript uses super() Python uses super().__init__() 💡 Key Takeaway: OOP makes code modular, reusable, and scalable. Understanding classes, constructors, this, inheritance, and super() builds a strong foundation for advanced JavaScript development. Step by step, moving towards mastering JavaScript. #JavaScript #OOP #WebDevelopment #FrontendDevelopment #Programming

🚀 New Blog Posted... Hello Developers 🖐, We often start learning JavaScript by writing code, but many struggle to truly understand what happens behind the scenes. So I wrote a beginner-friendly article explaining the core building blocks of JavaScript: • Variables • Data Types • Scoping • var, let, and const In this article, I break down these concepts in the simplest way possible with visual explanations and practical examples so beginners can understand how JavaScript actually works under the hood. If you're starting your JavaScript journey or revising fundamentals, this will help. 🗒️Read the full article here 👇 : https://lnkd.in/ge26UnkM Feedback from fellow developers is always welcome.

I also used simple real-world examples like blueprints and objects to make the concept easy to understand. 📖 Read the full article here: https://lnkd.in/gKUGBNMR Inspired by the amazing teaching of Hitesh Choudhary Sir and Piyush Garg Sir from Chai Aur Code . ☕💻 #javascript #webdevelopment #oop #learninginpublic #chaiAurCode

New Blog Published: Understanding Object-Oriented Programming in JavaScript Object-Oriented Programming (OOP) is one of the most important concepts in software development. While learning JavaScript, understanding how classes, objects, and the four pillars of OOP work can greatly improve the way we structure and manage code. In this article, I explain: • What Object-Oriented Programming means • Classes and objects in JavaScript • The constructor method • The four pillars of OOP: Encapsulation, Abstraction, Inheritance, and Polymorphism • Simple examples to understand these concepts clearly My goal was to break down OOP in a simple and beginner-friendly way, especially for developers who are starting their JavaScript journey. I would really appreciate your feedback and thoughts. Special thanks to the mentors and community whose content has been very helpful during my learning journey: Hitesh Choudhary Piyush Garg Akash Kadlag Jay Kadlag Anirudh J. Also grateful to the amazing community at Chai Aur Code for continuously sharing knowledge and learning resources. 📖 Read the article here: https://lnkd.in/dQjcnbqJ #javascript #webdevelopment #oop #programming #learninginpublic

It finally "clicked" - what Object-Oriented Programming (OOP) actually means. This is pivotal for Python and even JavaScript with React. You might even say it's a "key" concept, a very "value"-able part of the language. And when you "pare" it down to basics, you are left with objects. Anyway, I already knew about and used objects, and learned about “object-oriented programming” several times, but for some reason did not connect the two concepts. But yes, object oriented programming (OOP) is called such because it is a language that includes the variable type of objects. It boils down to that. For some reason, I once mistakenly thought of the objects in object-oriented programming as different from the variable type objects, like perhaps something visual, like an “object” moving around the page during a game for example. For example, the ball in Pong having different values to describe it - an X and Y position. Now, that's not too far off. But objects can represent so much more than that example. Yes, you can use an object to represent something on a page, but an object is basically a variable with one or more key-value pairs inside, each key-value pair basically being another variable inside that object. Later, I assumed the object vs. functional programming distinction meant that OOP did not frequently use loops and if statements. But JavaScript disproves that. Of course, I might still be misunderstanding something, so anyone can comment to add further clarifications. #OOP #ObjectOrientedProgramming #Python #JavaScript #Programming #Programmer #Coding

🚀 Today I publish my New article on Advanced Arrays in JavaScript-Beyond the Basics in JavaScript 🚀 In this article, I explored powerful array methods that are help to write short, clear and more professional code compared to traditional loops. This methods are not just about syntax but they improve readability, scalability and other problem solving skills in real project. While learning JavaScript step by step. I'm realizing that growth happens when we move from basics to writing smarter and more structured code. This topic truly helped me to think in more functional way. 📖 Read the full article here: 👉 https://lnkd.in/gi8t8dNz #JavaScript #LearnToCode #Programming #ArrayMethods #WebDeveloper

🚀 Day 81 JavaScript OOP: What I Learned Recently Recently, I dived deeper into Object-Oriented Programming (OOP) in JavaScript, and honestly, it changed the way I look at writing code 👇 🔹 Prototypes (Core Concept) Before classes, JavaScript used prototypes for inheritance. Every object is internally linked to another object. Understanding this made everything else much clearer. 🔹 Factory Functions Functions that return objects. Very simple and beginner-friendly, but not memory efficient because each object stores its own copy of methods. 🔹 Constructor Functions & new Using the new keyword, we can create multiple objects efficiently. Methods are shared using prototypes, which saves memory. 🔹 Classes (Modern JavaScript) ES6 introduced classes, making code cleaner and easier to read. But the important thing is — classes are just syntactic sugar over prototypes. 🔹 Inheritance With extends and super(), we can reuse code and build scalable applications. This is where OOP becomes really powerful. 🔹 GET & POST Requests (Backend Basics) GET → used to fetch data (data visible in URL) POST → used to send data securely (data in request body) 💡 My Key Takeaways: ✔ JavaScript is flexible, not strictly OOP ✔ Understanding prototypes is more important than memorizing classes ✔ Writing structured code makes projects scalable and clean This journey helped me move from just writing code → to actually understanding how things work behind the scenes ⚡ Still learning, but getting better every day 🚀 #JavaScript #OOP #WebDevelopment #NodeJS #LearningJourney #Coding

Just published a new blog: Understanding Objects in JavaScript In this article, I explain: • What objects are and why they are needed • Key–value pair structure • Dot notation vs bracket notation • Updating, adding, and deleting properties • Looping through object keys • Clear comparison between arrays and objects The goal was to keep it beginner-friendly and practical with simple examples. If you are currently learning JavaScript, this will strengthen your fundamentals. https://lnkd.in/gWYSbncC #JavaScript #WebDevelopment #FrontendDevelopment #Programming #Coding #LearnToCode #100DaysOfCode #SoftwareDevelopment #TechLearning

Behind every JavaScript feature we use daily, there is a deeper engine running underneath.
