Prototypes in JavaScript (The Secret Behind Everything) JavaScript doesn’t use classical inheritance like Java or C++ 👉 It uses Prototypal Inheritance --- 💡 Every object in JS has a hidden link: "[[Prototype]]" --- ⚡ Example: const animal = { speak() { console.log("Animal speaks"); } }; const dog = Object.create(animal); dog.speak(); // 🐶 Animal speaks --- 🤯 What just happened? - "dog" does NOT have "speak()" - JavaScript looks into its prototype - Finds it in "animal" 👉 This is called the Prototype Chain --- 🧩 Real Magic: [].map === Array.prototype.map // true 👉 That’s why arrays have methods like "map", "filter", etc. --- ⚠️ Important: dog.__proto__ === animal // true But avoid using "__proto__" directly Use "Object.getPrototypeOf()" --- 🚀 Why this matters: - Foundation of JS inheritance - Helps understand classes under the hood - Makes debugging easier --- Reference from 👉 Sheryians Coding School #javascript #webdevelopment #frontend #programming #coding

In this insightful article, Ramazan Maksyutov explores the connections between Atomic CSS and functional programming principles in web development. I found it interesting that viewing CSS through the lens of functional programming can lead to more modular and reusable styles. What are your thoughts on integrating functional programming concepts into CSS design? Read more here: https://lnkd.in/dwJN_NVv

Assalam o Alaikum everyone, JavaScript Lesson 28 is here: Classes & OOP. In this lesson, I explained one of the most important parts of modern JavaScript: Object-Oriented Programming with classes. You will learn how to create classes, use constructors, build instance methods, and work with `this` inside your objects. I also covered inheritance using `extends` and `super()`, so you can see how one class can reuse and expand another class. On top of that, I demonstrated getters and setters for computed properties, and static methods for utility-style behavior that belongs to the class itself rather than an individual object. In the code example, I used: • `Person` class for basic class structure   • `Student` class for inheritance   • `User` class for getters and setters   • `MathHelper` class for static methods  This lesson is useful if you want to understand how real-world JavaScript apps are structured and how OOP helps keep code clean, reusable, and organized.

🔥 Master the art of coding loops in JavaScript! 🚀 Loops are a fundamental concept in programming that allow you to execute a block of code multiple times. They are essential for automating repetitive tasks and iterating over data structures. For developers, understanding loops is crucial for writing efficient and concise code. Whether you're working on data manipulation, user interfaces, or backend logic, loops help you process large amounts of data with ease. Here's a step-by-step breakdown: 1️⃣ Initialize a counter variable 2️⃣ Set the condition for the loop to continue 3️⃣ Execute the code block inside the loop 4️⃣ Update the counter variable at the end of each iteration Check out the code example below: ``` for (let i = 0; i < 5; i++) { console.log('Hello, loop ' + i); } ``` Pro Tip: Use caution with infinite loops! Always ensure your loop has a clear exit condition to avoid crashing your program. Common Mistake Alert: Forgetting to update the counter variable in a loop can lead to infinite loops. Always remember to increment or decrement the counter inside the loop. 🌟 Question for you: What creative project are you currently working on with loops in your code?

🚀 Day 81 JavaScript OOP: What I Learned Recently Recently, I dived deeper into Object-Oriented Programming (OOP) in JavaScript, and honestly, it changed the way I look at writing code 👇 🔹 Prototypes (Core Concept) Before classes, JavaScript used prototypes for inheritance. Every object is internally linked to another object. Understanding this made everything else much clearer. 🔹 Factory Functions Functions that return objects. Very simple and beginner-friendly, but not memory efficient because each object stores its own copy of methods. 🔹 Constructor Functions & new Using the new keyword, we can create multiple objects efficiently. Methods are shared using prototypes, which saves memory. 🔹 Classes (Modern JavaScript) ES6 introduced classes, making code cleaner and easier to read. But the important thing is — classes are just syntactic sugar over prototypes. 🔹 Inheritance With extends and super(), we can reuse code and build scalable applications. This is where OOP becomes really powerful. 🔹 GET & POST Requests (Backend Basics) GET → used to fetch data (data visible in URL) POST → used to send data securely (data in request body) 💡 My Key Takeaways: ✔ JavaScript is flexible, not strictly OOP ✔ Understanding prototypes is more important than memorizing classes ✔ Writing structured code makes projects scalable and clean This journey helped me move from just writing code → to actually understanding how things work behind the scenes ⚡ Still learning, but getting better every day 🚀 #JavaScript #OOP #WebDevelopment #NodeJS #LearningJourney #Coding

30 Days JavaScript Challenge: Day 23 ✅ Today’s problem was about building our own version of groupBy() something that’s actually super useful in real projects. The idea was simple: Take an array, run a function on each element, and group elements based on the key that function returns. What I liked about this one is how it makes you think about data transformation not just looping, but structuring data in a cleaner and more usable way. Something like: Group users by id Split numbers based on a condition Organize data for UI rendering All of this becomes much easier once you understand this pattern. Another small step, but feels like I’m getting better at writing cleaner and more practical JavaScript. #javascript #leetcode #webdevelopment #frontenddeveloper #codingchallenge #learninginpublic #developers #programming #buildinpublic
