🛑 Still using this to deep clone objects in JavaScript? JSON.parse(JSON.stringify(obj)) It works… until it doesn’t 😅 It breaks with: ❌ Dates (turn into strings) ❌ Maps / Sets (lost completely) ❌ undefined & functions (removed) ❌ Circular references (throws error) JavaScript now has a modern, safer solution: structuredClone(obj) ✨ Supports circular references ✨ Preserves Date, Map, Set, RegExp ✨ Faster & built-in in modern JS/Node I wrote a simple blog with easy examples explaining why this matters, including a quick view of Shallow vs Deep cloning so the concept is crystal clear even for beginners. 🔗 Read it here: https://lnkd.in/dVcGiNwv #JavaScript #WebDevelopment #Programming #NodeJS #TypeScript #JSTips #CleanCode #SoftwareEngineering #Developers #WebDev #CodingLife

💼 Understanding Object Copying in JavaScript is essential for writing maintainable and scalable code. 📘 This guide clearly explains the difference between shallow and deep copy, helping developers make informed decisions and avoid hidden data mutation issues. #javascript #webdevelopment #programming #coding #softwareengineering #frontenddevelopment #webdev #codingtips #developer #tech #programmingtips #js #softwaredevelopment #codenewbie #learntocode

JavaScript Deep Dive: The Story Behind null Today, I explored the origins of one of JavaScript’s quirkiest features — null. It turns out this little value has a surprising history! 🔹 Where it Began: JavaScript was created in 1995 by Brendan Eich in just 10 days. Since it was inspired by Java, null was included to represent the intentional absence of any object — just like in Java. 🔹 The Famous Bug: Ever wondered why this happens? typeof null // "object" This result is actually due to an early implementation bug. null was given the same type tag as objects — and fixing it would have broken lots of existing code. So it stayed. 😅 🔹 null vs undefined: JavaScript defines two empty values: null: Intentionally empty (set by programmers) undefined: Automatically assigned by JavaScript for missing or uninitialized values This distinction has confused developers for decades! 🔹 Standardized in ECMAScript: Both null and undefined were formalized in the first ECMAScript standard (1997), cementing their roles in the language. 💡 Takeaway: JavaScript's null is a great example of how early design decisions — even mistakes — can shape a language's future. Knowing its history helps us write code with more clarity and intention.

Building Pulse — a small language for deterministic concurrency in JavaScript Over the last few months, I’ve been working on something I’ve always wished JavaScript had by default: deterministic concurrency. In most cases, JS async behavior depends on the event loop, Promise.race, or microtasks. That means timing, order, and scheduling aren’t truly predictable - even if your code looks flawless. Small differences can change execution order in ways that are hard to trace. Pulse is a small experimental language that compiles to JavaScript (ES Modules) but runs on its own deterministic runtime. Under the hood, it’s reactive like Solid or Svelte, but it also brings in Go-style concurrency as a first-class concept. Why I built Pulse I spend most of my time switching between JavaScript and Python. I wanted something that felt as expressive as JS, but with concurrency I could actually rely on - no hidden race conditions or random task order. When I say deterministic, I mean that the same program should behave the same way every time it runs. No invisible timing gaps, n https://lnkd.in/dx7PhMd4

I used to think JavaScript was an asynchronous language. Turns out, it’s actually synchronous by design. It executes one line at a time in a single thread. But here’s where it gets cool. Thanks to the event loop and features like callbacks, promises, and async/await, JavaScript can handle asynchronous tasks without freezing the page. So while one task runs, another can wait in line without blocking the main thread. In other words, JavaScript behaves synchronously but can act asynchronously. That balance is what makes it so powerful on the web. Other languages: Python and Ruby are mostly synchronous. Go and Rust support true parallelism. C++ and Java use multithreading. But JavaScript is unique. It doesn’t just run code, it choreographs it. These complex dynamics are what make picking JavaScript as my first language worth it. Behind every smooth animation, instant search result, or real-time notification, there’s a little async magic doing the heavy lifting. And once you understand the event loop, it honestly feels like you’ve unlocked one of programming’s secret cheat codes. #JavaScript #WebDevelopment #Coding #AsyncJS #SoftwareEngineering #ProgrammingHumor #TechMindset #WTFC25

🧱Objects — The Foundation of Everything in JavaScript 🗓️ This week, I focused on JavaScript Objects — and honestly, it changed how I see the language. From arrays to functions, almost everything in JS is built on objects. 💡Learning about prototypes, object methods, and inheritance made me realize how JavaScript manages structure without strict classes. “In JavaScript, objects don’t just hold data — they define behavior.” Once you get comfortable with the prototype chain, JS starts to feel less confusing and more elegant. #JavaScript #OOP #Programming #WebDevelopment #Frontend #CodingJourney #Developers

⚙️ Ever wondered how JavaScript actually executes your code behind the scenes? 🤔 It’s not magic — it’s how the engine works! 🚀 👉 The JavaScript Engine (like V8) runs your code in two main phases: 1️⃣ Memory Creation Phase – Variables and functions get allocated in memory. 2️⃣ Execution Phase – Code runs line by line inside the Call Stack. 🧠 When asynchronous tasks (like setTimeout, API calls, or Promises) come in — they move to the Web APIs, then to the Callback Queue / Microtask Queue, and finally back to the Call Stack through the Event Loop. That’s the secret sauce of how JavaScript handles concurrency and non-blocking execution so smoothly! 💫 #javascript #webdev #frontend #coding #softwareengineering #reactjs #nodejs #programming #developers #typescript #LearningEveryday

Today’s Tiny JavaScript Project I wrote a simple “Fortune Teller” script in JavaScript — it picks a random fortune each time you run it! let fortune1 = "Your cat will look very cuddly today."; let fortune2 = "The weather will be nice tomorrow."; let fortune3 = "Be cautious of your new neighbors."; let fortune4 = "You will find a new hobby soon."; let fortune5 = "It would be wise to avoid the color red today."; let randomNumber = Math.floor(Math.random() * 5) + 1; let selectedFortune = randomNumber; if (randomNumber === 1) selectedFortune = fortune1; else if (randomNumber === 2) selectedFortune = fortune2; else if (randomNumber === 3) selectedFortune = fortune3; else if (randomNumber === 4) selectedFortune = fortune4; else if (randomNumber === 5) selectedFortune = fortune5; console.log(selectedFortune); 🧠 It’s a small project, but a fun way to practice: Random number generation Conditional logic Console output What fortune did you get when you ran it? 👀 #JavaScript #Coding #WebDevelopment #100DaysOfCode #LearnToCode
