JavaScript OOP Tutorial: Objects, Constructors, Prototypes, and Memory

Something useful today. Maps and Sets in JavaScript: A Deep Dive JavaScript provides several ways to store and manage data, with objects and arrays being the most commonly used structures. However, when dealing with unique values or key-value pairs with better efficiency, Maps and Sets come to the rescue!

🚨 JavaScript Objects vs Classes — Still Confusing? If you’ve ever struggled with this… you’re not alone. 😅 Most developers think: 👉 Classes = OOP 👉 Objects = Instances But in JavaScript, things work a bit differently… 💡 Reality: Objects are the core of JavaScript (everything revolves around them) Classes are just a clean syntax (ES6) to create objects more easily Under the hood, JavaScript is still prototype-based, not class-based 👉 That’s why confusion happens. Object = Real data (actual thing) Class = Blueprint (structure/template) ⚡ The biggest mistake beginners make: Trying to learn JavaScript like Java or C++ 👉 But JavaScript has its own way of thinking. 🎥 I explained everything clearly in this video: https://lnkd.in/dw7Z5HCN 💬 Be honest… Did "objects vs classes" confuse you when you started? 😄 #JavaScript #WebDevelopment #Coding #Programming #Frontend #NodeJS #ReactJS #Developers #LearnToCode #CodingLife #Tech #SoftwareDevelopment #JavaScriptTips #FullStack #DeveloperCommunity

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.

In today in class, got a great explaination by Suraj Kumar Jha core Object-Oriented Programming (OOP) concepts in JavaScript. We covered prototypes & constructor functions, modern class features (new, static, private, super), as well as getters and setters. Also revisited key OOP principles like inheritance, polymorphism, encapsulation, and abstraction. Strengthening these fundamentals is helping me better understand how JavaScript works under the hood and write more structured, scalable code #JavaScript #OOP #WebDevelopment #LearningJourney

Sharing beginner-friendly notes on Advanced Functions in JavaScript 🧠 Covered two of the most important concepts every JS developer needs to master, Closures and Higher-Order Functions. The guide walks through how closures "remember" their lexical scope, enabling data privacy, memoization, and function factories. Also explored essential Higher-Order Functions like map, filter, reduce, and practical utilities like debounce, throttle, curry, and compose with clear examples and visual diagrams. A practical guide for understanding how functions truly work under the hood. Feedback and suggestions are welcome! #JavaScript #Coding #Learning #Programming
