Object-Oriented Programming in JavaScript: The Blueprint Factory You Never Knew You Needed

"Good code is like a well-organized factory — everything has its place, and every worker knows their job." Modern software development isn't just about writing code — it's about organizing code so it's reusable, scalable, and maintainable. That's exactly what Object-Oriented Programming (OOP) gives you. If you're learning JavaScript, understanding OOP is a game-changer. Let's break it down the right way — with real-world analogies, clean diagrams, and code you can actually use. 📌 Table of Contents What is OOP?
