The 24 hour JavaScript Engine. Just for the hell of it, I pushed my JavaScript Engine experiment further. I have pretty decent coverage of JS features now. * Event loop * Promises * Async Await ( CPS Transformers ) * Generators ( CPS Transformers ) * Class syntax, with inheritance It´s been an interesting thing to play with. It really does help to have the proper background in languages, interpreters and compilers. It all runs on-top a form of LISP-like engine. JavaScript code -> JavaScript AST -> S-Expressions -> CPS Transformer -> S-Expression evaluator engine. There are probably conceptual things in that decision that will be hard to align with strict JavaScript. I don´t know the edgecases or details of JS that well. But so far it has worked out incredibly well. Some funny takeways. Due to the expression-first approach in the inner engine, every expression is evaluated recursively. This means there is no way "break out" of a function. e.g "return" inside nested conditionals. The AI solved this though. Using Exceptions in .NET. Setting up Try Catch for specific "Signals" in the evaluator. Then when it returns a value, it actually throws an exception holding on to the result. Catching it where the consumer of that value sits. Very Similar with "continue" and "break" statements. This is of course not performant in any way, but it does work. surprisingly well too. Either way, it´s a toy project. just prompting. If anyone is interested in languages, parsing, interpreters. or just want to play with it, here is the code: https://lnkd.in/dTwzgqwu

🚀 Immutability in Functional JavaScript Immutability is the principle of not modifying data after it's created. Instead of changing existing objects or arrays, we create new ones with the desired modifications. This prevents unexpected side effects and makes it easier to track data changes over time. JavaScript provides tools like `Object.assign`, the spread operator (`...`), and libraries like Immutable.js to help manage immutability. 🎓 The more you learn, the more you earn! ⚡ Fast-track your learning — 10,000+ concepts, 4,000+ articles, 12,000+ quizzes.

JavaScript's Iterators and Iterables – often perceived as a linguistic maze, yet their underlying mechanics are foundational to building truly performant and scalable applications. Beyond just syntax, understanding the distinction between an object that *can be iterated over* (iterable) and the *singular, stateful act of iteration itself* (iterator) reveals a deeper magic in how data flows through our systems. It's not just about looping; it's about controlled, efficient, and predictable data traversal. For businesses aiming to build robust web or mobile solutions, this "deep magic" is far from academic. It's about optimizing resource management, ensuring predictable data processing, and avoiding pitfalls like memory leaks in high-load scenarios. Whether I'm architecting efficient data streams in a Python backend, optimizing rendering of large datasets in a React application, or handling asynchronous operations in a Laravel API, leveraging these principles of controlled, stateful data traversal empowers me to deliver resilient and performant systems tailored for growth and scalability for my clients. What "deep magic" concept in JavaScript, or any language, do you find most impactful for building production-ready applications, and why? #JavaScript #SoftwareDevelopment #TechConsulting #WebDevelopment #SoftwareEngineering

JavaScript Prototypes: The Moment Everything Finally Made Sense 🚀 I spent years writing JavaScript without understanding what was really happening under the hood. 🤔 Then one day, I noticed something that didn't make sense: Why can I call methods on primitive strings when they're not even objects? How does dot notation work on a simple text value? This simple question sent me down a rabbit hole that completely changed how I think about JavaScript. 🤨 Here's what I discovered: ✨ Every object has a hidden __proto__ property that creates inheritance chains ✨ JavaScript temporarily "wraps" primitives to give them object-like behavior ✨ The prototype system is what makes inheritance actually work ✨ Classes are just syntactic sugar over prototypes ✨ Understanding this unlocks why JavaScript behaves the way it does I documented my entire journey - from confusion to clarity - in a detailed article where I: → Experimented with prototype chains → Built real-world examples (API clients, databases) → Solved the primitive methods mystery → Explained __proto__ vs prototype once and for all Whether you're a beginner trying to understand JavaScript or an experienced dev who wants to know what's happening behind the scenes, this deep dive breaks it down step by step. 🔗 Read the full article: https://lnkd.in/g26HR8x7 Have you ever wondered about JavaScript's prototype system?

Anders Hejlsberg began working on TypeScript in 2012 with a specific goal in mind: addressing a practical challenge rather than creating a competitor to JavaScript. At that time, JavaScript was pivotal to web development, yet it faced limitations in scaling for extensive, collaborative code projects. The industry witnessed the delivery of vast amounts of weakly typed code, leading to complexity beyond manageability as systems expanded. https://lnkd.in/guf6_kEu #javascript #frontend #typescript #ai

Let me confess something......... In my early days, "React", "TypeScript", "Next.js" and "DSA" looked shiny and exciting. Meanwhile, I was still fighting Javascript and stuck in tutorial hell, hoping the next video would finally make sense. It never did......!!!! I barely understood my own code, but I still believed I “knew Javascript.” Eventually I realised No one knows a language 100%. 50% simply means everyone is always learning, because this field never stops evolving. I used to avoid documentation, but "MDN docs", "javascript.info" and many other Documentations changed everything. Concepts finally connected. Errors made sense. And even if you love “vibe coding,” fundamentals are what save you. They reduce your 10 AI prompts to 2. AI will not replace you now, it will just watch you write longer prompts. So if you are starting out Just Remember these slow down, learn your basics, and read documentation. #GoingBackToBasics #Frontend #JavaScript

Understanding How JavaScript Manages Memory: Stack, Heap & Garbage Collection As developers, we often use JavaScript every day, but few of us pause to think about how it really manages memory behind the scenes. 🧠 Memory Types: - Stack Memory: Stores primitive data types (like numbers, strings, booleans). These are copied by value — meaning every variable gets its own copy. - Heap Memory: Stores non-primitive data types (like objects, arrays, functions). These are copied by reference — multiple variables can point to the same memory location. 🧹Garbage Collection: JavaScript automatically cleans up unused memory through a process called Garbage Collection, based on the concept of reachability. How It Works Reachability: JS keeps objects in memory if they are reachable (accessible from roots. Unreachable Objects: If an object is no longer referenced, it becomes eligible for garbage collection. Mark-and-Sweep Algorithm: Mark: Identify all reachable objects. Sweep: Delete objects not marked as reachable. Does understanding memory management change the way you write JavaScript? #JavaScript #WebDevelopment #Frontend #MemoryManagement #CodingTips #Developers

The Only SOLID + Clean Code JavaScript Guide You Need in 2025 Prefers video content? Here are the 5 SOLID programming principles explained, applied to JavaScript (in English) Modern JavaScript in 2025 demands more than just “making code work.” We now build scalable front-end apps, distributed back-ends, microservices, serverless functions, and highly interactive UIs. As systems grow, readability and maintainability become far more valuable than simply shipping features. In this guide, you’ll learn: What SOLID means (in simple language) How to write cleaner, maintainable, testable code How developers in 2025 use tools like AI, linting, and even picture text tools to streamline their workflow Let’s begin. What is Clean Code (2025 Definition)? Why SOLID Still Matters in Modern JavaScript - S — Single Responsibility Principle (with ES6 example) - O — Open/Closed Principle (with real pattern) - L — Liskov Substitution Principle (practical example) - I — Interface Segregation Principle (JS-friendly explanation) - D — Dependency Inversion Principle https://lnkd.in/gNZ49DNK
