Understanding JavaScript OOP with Suraj Kumar Jha

Day 98 of my #100DaysOfCodeChallenge Today I explored Object-Oriented Programming in JavaScript using classes. Here’s what I worked on: Built a Product class with methods to display details and calculate total price Learned how constructors initialize object properties Implemented static properties and methods using a utility class Created a User class to track the number of users created This helped me understand the difference between instance-level and class-level behavior, and how to structure code more effectively. It’s a shift from just writing functions to designing systems. #JavaScript #OOP #WebDevelopment #SoftwareEngineering

Sharing beginner-friendly notes on Object-Oriented Programming (OOP) in JavaScript 🧠 Covered core concepts like Classes, Constructors, Inheritance, Encapsulation, Polymorphism, Getters/Setters, Static methods, and Private fields (#) with clear examples. Also explained how super, instanceof, and prototypes work behind the scenes. A practical guide to understanding how OOP works in modern JavaScript. Feedback and suggestions are welcome! #JavaScript #OOP #Coding #Learning #Programming

Chai aur TypeScript – Day 12 🚀 Today I learned about OOP (Object-Oriented Programming) in TypeScript. 🔑 Key Learnings: • Classes & constructors for object creation • Access modifiers → public, private, protected • readonly → properties cannot be changed • Getters & setters → controlled access • static → belongs to class, not instance • abstract → blueprint for other classes • Composition → alternative to inheritance 💡 Big Insight: TypeScript makes OOP more structured and type-safe #ChaiAurTypescript #TypeScript #JavaScript #LearningInPublic #DeveloperJourney #ChaiCode Hitesh Choudhary Chai Aur Code

I recently shared a short blog where I explain Object-Oriented Programming (OOP) in JavaScript along with its four core concepts — Encapsulation, Inheritance, Polymorphism, and Abstraction — using simple and beginner-friendly examples 💡 If you're learning JavaScript or just brushing up your OOP fundamentals, this might be useful for you 🚀 👉 Read the blog here: https://lnkd.in/g-B4g5gk Hitesh Choudhary | Piyush Garg | Suraj Kumar Jha | Chai Code | Akash Kadlag ☕ #JavaScript #OOP #WebDevelopment #Programming #LearnInPublic #Blog #Cohort2026

I recently wrote a short blog explaining Object-Oriented Programming in JavaScript and its four core principles: Encapsulation, Inheritance, Polymorphism, and Abstraction, with simple examples.

I have been recently having fun with Javascript and I recently create about 3hours plus video trying to explain concept like Object Oriented programming(OOP), Async/Await and Promise in Javascript. For the OOP part, I talked about the four features of OOP which: 1. Abstraction 2. Encapsulation 3. Inheritance 4. Polymorphism. I also talked about the three ways someone can implement OOP in Javascript which are through the class, Object.create and through contructor function. I also talked about the fact that Js does not really have true class but a synthetic sugar implementation over constructor function/prototypal inheritance. For the Async part, I talked about asynchronous Javascript, Event loop, Callback Queue, Promises, resolving promises and how to basically promisify an async functions.

🚀 I’m sharing a presentation I created about Object-Oriented Programming (OOP) This material was used in a professional setting and covers key concepts such as: ✔️ Abstraction ✔️ Encapsulation ✔️ Inheritance ✔️ Polymorphism I believe mastering these pillars is essential to writing scalable and maintainable code. 💻 Technologies: JavaScript / Object-Oriented Programming I’d love to hear your feedback! #programming #oop #webdevelopment #javascript #backend #frontend

Just published a new blog post on Event-Driven Programming in Node.js This article explains how the event-driven architecture works in Node.js using concepts like events, listeners, and the EventEmitter. I’ve also included simple code examples to help you clearly understand how Node.js handles asynchronous operations in real-world applications. If you're learning Node.js, this is an important concept to master! Read more: https://lnkd.in/dnEkxux4 #NodeJS #JavaScript #BackendDevelopment #WebDevelopment #Programming #SoftwareEngineering

30 Days JavaScript Challenge : Day 26 ✅ Today’s problem was about flattening a multi-dimensional array, but with a twist we were given a depth n and had to flatten only up to that level. Not a full flatten, not a shallow one… somewhere in between. It really makes you think about recursion and depth control: When to go deeper When to stop How to keep track of current depth What I liked is how this problem builds intuition around nested data structures something you see a lot in real apps (APIs, configs, UI trees, etc.). Slowly getting more comfortable with recursion and thinking in layers. #javascript #leetcode #webdevelopment #frontenddeveloper #codingchallenge #learninginpublic #developers #programming #buildinpublic

Mastering JavaScript Arrays Made Simple! Understanding JavaScript array methods is a game-changer. They help you write cleaner, more efficient code without relying on lengthy loops.
