Understanding Object-Oriented Programming in JavaScript

🚀 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

Today, I learned something interesting about numbers in JavaScript. For example: 0.1 + 0.2 = 0.30000000000000004  But 1.1 plus 1.2 equals 2.3 In simple terms: JavaScript doesn't store numbers in decimal form; it stores them in binary (0s and 1s). Binary can't store some decimal numbers exactly, like 0.1 and 0.2. This means that a very small error is added when you do math. That's why you might see results like 0.30000000000000004. Temporary Fixes : Use Math.round : Math.round((0.1 + 0.2) * 100) / 100  Use toFixed:  (0.1 + 0.2).toFixed(2)  Use Math.floor or Math.ceil: Math.floor((0.1 + 0.2) * 100) / 100  //when rounding off lower value Math.ceil((0.1 + 0.2) * 100) / 100 //when rounding off to upper value This is not a bug in JavaScript. It happens because of how most programming languages store floating-point numbers. #JavaScript #Coding #WebDevelopment #Programming #100DaysOfCode

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

Maps and Sets in JavaScript: A Beginner-Friendly Guide JavaScript provides many ways to store and manage data. While Arrays and Objects are widely used, Maps and Sets are two powerful yet often overlooked data structures....

📚 JavaScript: Array vs Object 💡 Many beginners get confused between Array and Object in JavaScript. But the difference is actually very simple 👇 ✅ Array • Used to store a list of items • Values are ordered • Access items by index like 0, 1, 2 Example: ["Apple", "Mango", "Banana"] ✅ Object • Used to store key-value pairs • Best for structured data • Access values by key Example: { name: "John", age: 25 } 👉 Use Array when you need a list. 👉 Use Object when you need data with labels. Understanding this basic concept makes JavaScript much easier to learn 🚀 #JavaScript #WebDevelopment #Programming #FrontendDevelopment #Coding #ReactJS #LearnJavaScript #Developer #TechCommunity #100DaysOfCode

30 Days JavaScript Challenge : Day 27 ✅ Today’s problem was about creating a compact object basically removing all falsy values from an object or array, even if they are nested. At first glance it looks easy, but once nested structures come in, it gets interesting. This problem really tests your understanding of: Falsy values (null, 0, false, "", etc.) Recursion for nested objects/arrays Treating arrays like objects (since indices are keys) It’s one of those questions that feels very practical like cleaning API responses or filtering unwanted data before using it. Definitely helped me think more deeply about how JavaScript handles data structures. Almost at the end now… consistency paying off 🚀 #javascript #leetcode #webdevelopment #frontenddeveloper #codingchallenge #learninginpublic #developers #programming #buildinpublic

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

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!
