“Class-based components are dead in React.” True. But here’s what most developers get wrong 👇 👉 OOP is NOT about React components. 👉 It’s about structuring complex systems. After 5+ years in frontend development…  I went back to revisit Object-Oriented Programming in TypeScript. Sounds basic, right? But here’s what I’ve learned 👇 👉 Most frontend code breaks at scale—not because of React… …but because of poor structure. Not to write class components… But to solve real problems I’ve faced in large applications • Managing complex business logic outside UI • Building reusable, scalable modules • Avoiding tightly coupled and messy codebases While working on large applications (dynamic forms, dashboards, enterprise systems), I’ve seen: • Components becoming tightly coupled • Business logic scattered across files • Code getting harder to maintain with every feature Revisiting OOP concepts in TypeScript helped me rethink: ✔ How to structure scalable and reusable modules ✔ When to use classes vs functional patterns ✔ Writing cleaner, maintainable, and predictable code ✔ Encapsulating logic cleanly ✔ Designing reusable services/utilities The biggest realization? 👉 Functional for UI 👉 OOP for structure 👉 Good UI ≠ Good Architecture 👉 Scalable systems come from strong design patterns Good frontend engineering is not about choosing one— It’s about knowing when to use what. — How do you approach architecture in large React applications—OOP, functional, or a mix? #TypeScript #OOP #FrontendArchitecture #ReactJS #SoftwareEngineering #CleanCode

🚀 Day 06 of Learning TypeScript — Modules, Classes & Inheritance Today’s learning was focused on understanding how TypeScript helps us write scalable and structured code using concepts like modules, classes, access modifiers, and inheritance. 🔹 1. Modules (import / export) Learned how to split code into reusable files using modules. ✔ Better code organization ✔ Reusability across files ✔ Clean project structure 🔹 2. Classes in TypeScript Classes help in creating structured and reusable blueprints. ✔ Encapsulates data + behavior ✔ Foundation of OOP in TS 🔹 3. Access Modifiers Controlled access to properties using: public → accessible everywhere private → accessible only inside class protected → accessible in class + child class Person { protected name: string; constructor(name: string) { this.name = name; } } ✔ Improves security & code control 🔹 4. Inheritance (extends) Learned how one class can reuse another class. ✔ Code reusability ✔ Cleaner architecture ✔ Avoids duplication 💡 Key Takeaways Modules → organize large codebases Classes → blueprint for objects Access Modifiers → control visibility Inheritance → reuse and extend functionality 🔥 TypeScript is becoming more powerful day by day — now moving towards writing scalable, production-level code. #typescript #webdevelopment #javascript #learning #programming #developers #100DaysOfCode #frontend

Most developers don’t fail because they can’t code… They fail because they don’t optimize. Understanding Time Complexity is what separates: 👉 Beginners from professionals 👉 Working code from scalable systems Here’s a simple cheat sheet to keep in mind while coding. 💡 Remember: “Efficiency > Just making it work” #Programming #DataStructures #Algorithms #Coding #SoftwareEngineering #NodeJS #TechCareers

Should you learn one programming language or many? I think it depends more on your role than the number itself. Frontend, backend, and full-stack developers all work on different parts of a system, so the tools naturally differ too. Instead of focusing on how many languages to learn, I now think more about: What part of the system am I working on, and what actually fits there? Wrote more on it here: https://lnkd.in/g-8uAREE

🚀 Async Code in Node.js: Callbacks and Promises Read full article here: https://lnkd.in/g6_bah4Z Asynchronous programming is one of the most important concepts to understand in Node.js. Since Node.js is non-blocking, async code allows multiple operations to run efficiently without stopping the execution flow. In this article, I explored how Node.js handles async operations using callbacks and promises. 📌 What I covered: • Why async code exists in Node.js • Callback-based async execution • Problems with nested callbacks (callback hell) • Promise-based async handling • Benefits of promises 💡 Key Insight: Callbacks work, but as applications grow, nested callbacks make code harder to read and maintain. Promises solve this by making asynchronous code cleaner, more readable, and easier to manage. A simple file-reading example helped break down the flow step by step and compare callback vs promise readability. 🙏 Special thanks to my mentors and teachers from Chai Aur Code — Hitesh Choudhary Sir, Piyush Garg Sir, Suraj Kumar Jha Sir, and Akash Kadlag Sir for their amazing guidance and teaching. If you're learning Node.js, mastering async programming is essential for writing scalable backend applications.

🚀 Diving Deeper into JavaScript: Classes & Objects As part of my continuous learning journey in JavaScript, I recently explored one of the most important paradigms in modern development — Object-Oriented Programming (OOP). Here’s a quick snapshot of what I’ve learned: 🔹 Objects are the core building blocks that encapsulate state (data) and behavior (methods) 🔹 Classes act as blueprints to create multiple reusable object instances 🔹 Understanding the prototype chain helped me see how JavaScript handles inheritance behind the scenes 🔹 Implemented inheritance to reuse and extend functionality across classes 🔹 Used the constructor() method for initializing object properties effectively 🔹 Learned how the super keyword connects child classes to parent class functionality 🔹 Explored error handling (try-catch) to make applications more robust and fault-tolerant 💡 This learning not only strengthens my fundamentals for real-world project development but also builds a strong base for technical interviews. 📂 I’ve also worked on: ✔️ Practice questions ✔️ Study materials ✔️ Hands-on examples 📄 I’ll be attaching the detailed learning resource (PDF) for anyone interested in revising or getting started with OOP in JavaScript.

The new version of the programming language with a Go backend is said to be ten times faster than its predecessor, which used the JavaScript codebase.

🚀 Mastering the art of asynchronous programming! 🛠 Understand how asynchronous code works: the ability to run tasks concurrently without blocking the main thread. For developers, mastering this concept is crucial for writing efficient and responsive applications. Step by step breakdown: 1️⃣ Define the asynchronous function using the 'async' keyword. 2️⃣ Use the 'await' keyword inside the function to wait for promises to resolve. 3️⃣ Call the function and handle the returned promise accordingly. Full code example: ``` async function fetchData() { const response = await fetch('https://lnkd.in/gc8PxW6P'); const data = await response.json(); return data; } ``` Pro Tip: Remember to handle errors when working with asynchronous code. Use try-catch blocks to catch any exceptions that may occur. Common Mistake Alert: Avoid nesting too many asynchronous functions, as it can lead to callback hell and make the code harder to read and maintain. 🤔 What are some challenges you've faced while working with asynchronous JavaScript code? 🌐 View my full portfolio and more dev resources at tharindunipun.lk #AsyncProgramming #JavaScriptTips #WebDevelopment #AsynchronousCoding #ProDevTips #CodeLikeAPro #TechTalk #AlwaysLearning

Object-Oriented Programming (OOP) is still one of the most powerful ways to write scalable code — especially in TypeScript. But here’s the reality 👇 👉 Many developers use TypeScript… 👉 Few actually use OOP effectively. So I wrote a simple, practical guide covering: ✅ Core OOP concepts (Encapsulation, Inheritance, Polymorphism, Abstraction) ✅ Real-world TypeScript examples ✅ Interfaces & best practices ✅ When to use (and avoid) OOP If you're building scalable apps with Angular, Node.js, or any large system — this will help 👇 🔗 Read here: https://lnkd.in/dWzaiqEk 💬 What’s your take — do you prefer OOP or functional programming? #javascript #typescript #webdevelopment #programming #softwareengineering #angular #nodejs
