JavaScript Prototypes and OOP Fundamentals Explained

Today's JS Learning: Prototypes & OOP Pillars In today's class, we covered these core JavaScript concepts: 🔹 Prototypes & Constructors: Understanding the fundamental architecture of JS and how the new keyword actually works. 🔹 Classes: Learned that they are essentially Syntactic Sugar—a cleaner and more modern way to write Prototypal Inheritance. 🔹 Class Features: * Static Keyword: For methods that belong to the class itself. Getters & Setters: To control how we access and modify data. 🔹 The 4 Pillars of OOP: 1. Encapsulation: Keeping data secure. 2. Abstraction: Hiding complex implementation details. 3. Inheritance: Reusing code effectively. 4. Polymorphism: One interface, multiple forms.

🚀 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.

Strengthening Fundamentals: Implementing Selection Sort in JavaScript (Descending Order) Today, I focused on strengthening my understanding of fundamental algorithms by implementing Selection Sort in JavaScript to arrange an array in descending order. Working through the logic step by step provided valuable insight into how sorting algorithms operate internally—particularly the process of identifying elements and performing swaps efficiently without relying on built-in functions. Revisiting these core concepts is a great reminder that a strong foundation in data structures and algorithms is essential for writing optimized and scalable code. You can check out my implementation on my GitHub Looking forward to continuing this learning journey and exploring more advanced problem-solving techniques. #JavaScript #Algorithms #DataStructures #Development #ContinuousLearning #GitHub 😊

Most beginners start JavaScript… but don’t understand variables & data types deeply. They declare variables. Store values. Write basic code. It feels easy — until logic gets complex. Then the real problems start: Confusion in data handling. Unexpected bugs. Weak logic building. Difficulty scaling code. In 2026, JavaScript isn’t about syntax. It’s about building strong logic foundations. This is where it starts: • Understanding var, let, const clearly • Knowing different data types (string, number, boolean, object, array) • Storing and managing data efficiently • Writing clean and predictable logic • Avoiding common beginner mistakes Because strong logic doesn’t come from frameworks — it comes from mastering the basics. Curious — are your fundamentals strong or just “working somehow”? #JavaScript #WebDevelopment #Coding #Programming #FrontendDevelopment #LearnToCode #DeveloperLife #JSBasics

It’s easy to write code that works, but today I realised how little I actually understand what’s happening under the hood of JavaScript. But today's class felt like a proper brain reset—we moved from building APIs to exploring the language’s “engine room.” The whole prototype vs __proto__ thing finally clicked for me: one is the blueprint, the other is the actual DNA link objects use to climb their weird little family tree, looking for missing methods. Suddenly, memory efficiency made sense. Then came the OOP pillars, which sound fancy until your code turns into spaghetti. I now think of Encapsulation as a secret diary for variables, and Polymorphism as that one friend who behaves differently depending on the situation—same interface, multiple personalities. Even ES6 classes hit differently once I understood why static exists and how super() quietly connects everything behind the scenes. I’m slowly realising that becoming a better developer isn’t about writing more code, but thinking more before writing it. Still a part-time “professional Googler,” but as they say, that discomfort is where the real learning lives. Hitesh Choudhary, Piyush Garg, Akash Kadlag, Jay Kadlag

#Hello #Connections 👋 #100DaysOfCodeChallenge | #Day60 Project: Dev Languages Accordion UI What I built Today I built a Dev Languages Explorer with an accordion UI, where users can search and filter programming languages interactively. Technologies Used HTML5 CSS3 JavaScript (DOM, Search, Filtering, RegEx) Challenge I faced Combining search + filter + accordion state management together without breaking UI behavior. How I solved it Used efficient filtering logic + state management (Set) and implemented dynamic rendering with highlighted results. Features Search with keyword highlight Filter by categories Expand/Collapse accordion Dynamic results count Live Demo: https://lnkd.in/du8G8X59 Open to feedback and suggestions Code Of School Avinash Gour | Ritendra Gour #FrontendDeveloper #JavaScript #WebDevelopment #100DaysOfCode #DeveloperJourney #Coding #UIUX

🚀 A Major Update is Coming to CodeAlive (Live in 3–4 Days!) I honestly started CodeAlive as a small platform with a simple goal in mind — to let my code snippets live over the internet with support for custom sharable links. But seeing how far it has come now, evolving into a platform with so many useful and smart features for everyone, has been incredibly exciting. 🌐 CodeAlive – https://lnkd.in/gnthhf_b 👉 Also, you can click "View My Website" on my profile to visit the platform. What’s Coming Next ⏭️ CodeAlive is soon introducing: **Multi-Language Detection & Highlighting in a Single Code File** Problem: Almost every code-sharing platforms and online editors are built around one assumption: 1 File = 1 Language But real-world development is rarely that simple. Developers often share: ✅ Frontend + Backend snippets together ✅ Embedded scripts/styles ✅ Configurations with code ✅ Multi-language examples in one paste And when platforms force a single language highlight, readability suffers. With This New Update, CodeAlive Will Support ✅ Detecting multiple languages within one pasted code file ✅ Highlighting different sections based on actual context/language ✅ Making mixed-language snippets cleaner, smarter, and easier to read This has been one of the most exciting features to work on so far, and I can’t wait to share the full implementation details once it officially goes live. 📅 Expected Release: 3–4 Days Stay tuned 👀 More technical insights coming soon... #CodeAlive #BuildInPublic #Programming #SoftwareDevelopment #DeveloperTools #WebDevelopment #Python #JavaScript #StartupJourney

🔥 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?

🚀 𝗗𝗷𝘂𝗹𝗲 𝘃𝟮.𝟬.𝟬 𝗶𝘀 𝗵𝗲𝗿𝗲. Last weekend I released Djule v1. Today, v2 is already here. Djule started as an experiment to make server-rendered UI in Python feel more modern without needing a heavy frontend framework. In just a week, it has gone from an early parser/runtime foundation to something that feels much more like a real language and developer workflow. For anyone who has not seen it before: 𝗗𝗷𝘂𝗹𝗲 is a new templating language built on top of Django. It lets you build more expressive, component-based UI while still keeping Django’s server-rendered architecture. 𝗪𝗵𝗮𝘁’𝘀 𝗻𝗲𝘄 𝗶𝗻 𝘃𝟮: • 𝗛𝗧𝗠𝗟 𝗳𝗲𝗲𝗹𝘀 𝗺𝗼𝗿𝗲 𝗻𝗮𝘁𝘂𝗿𝗮𝗹 Native support Self-closing HTML and component tags Interpolated strings inside attributes Better multiline syntax for expressions and grouped values • 𝗖𝗼𝗺𝗽𝗼𝗻𝗲𝗻𝘁𝘀 𝗮𝗿𝗲 𝗲𝗮𝘀𝗶𝗲𝗿 𝘁𝗼 𝘄𝗿𝗶𝘁𝗲 𝗮𝗻𝗱 𝗿𝗲𝘂𝘀𝗲 Multiline component parameter lists Default component parameters Simpler props like error=True instead of error={True} • 𝗘𝗿𝗿𝗼𝗿 𝗺𝗲𝘀𝘀𝗮𝗴𝗲𝘀 𝗮𝗿𝗲 𝗺𝘂𝗰𝗵 𝗯𝗲𝘁𝘁𝗲𝗿 Clear parser diagnostics Real file and line context when something breaks Better import and component error reporting • 𝗗𝗷𝗮𝗻𝗴𝗼 𝗶𝗻𝘁𝗲𝗴𝗿𝗮𝘁𝗶𝗼𝗻 𝗶𝘀 𝗺𝘂𝗰𝗵 𝘀𝗺𝗼𝗼𝘁𝗵𝗲𝗿 Dedicated Django template backend Settings-aware import roots Support for Django-style global context processors and built-in tags That means Djule now works much more naturally inside a real Django project without needing a bunch of manual setup. 𝗧𝗵𝗲 𝗩𝗦 𝗖𝗼𝗱𝗲 𝗲𝘅𝘁𝗲𝗻𝘀𝗶𝗼𝗻 𝗮𝗹𝘀𝗼 𝗴𝗼𝘁 𝗮 𝗺𝗮𝗷𝗼𝗿 𝘂𝗽𝗴𝗿𝗮𝗱𝗲: • Live diagnostics while you type • Autocomplete for components, props, imports, globals, and snippets • Better import UX • Django-aware editor globals • Go-to-definition for components • Improved highlighting for newer Djule syntax v2 feels like the point where Djule starts becoming more than just “a parser I built” and starts feeling like a real language workflow. 👇 𝗬𝗼𝘂 𝗰𝗮𝗻 𝘁𝗿𝘆 𝗶𝘁 𝗵𝗲𝗿𝗲: PyPI: pip install djule VS Code Marketplace: rhxrr.djule Would love to hear what people think, especially from people building with Python or Django. #Python #Django #WebDevelopment #OpenSource #ProgrammingLanguages #VSCode #DeveloperTools
