JavaScript vs. TypeScript: Which Side Are You On? 🚀 Ever felt like your JavaScript code is holding on by a thread? 😅 Let's talk about the game-changer. On one side: JavaScript Flexible, dynamic, and quick to start But those runtime errors? They'll find you at the worst moments "Undefined is not a function" – sound familiar? On the other side: TypeScript Catch errors BEFORE runtime Better autocomplete = faster development Self-documenting code that your future self will thank you for Refactor with confidence, not fear The reality? TypeScript isn't about replacing JavaScript – it's about leveling up when your project grows beyond a certain scale. #JavaScript #TypeScript #WebDevelopment #Coding #SoftwareEngineering #DeveloperLife #SoftwareEngineering #WebDevelopment #ReactJS #NextJS #FrontendDevelopment #JavaScript #FullStackDeveloper #Programming #TechCareers #BuildInPublic

Day 3/200🚀 Understanding JavaScript Closures, Scope & setTimeout Today I explored a tricky but important JavaScript concept while experimenting with setTimeout, var, and let. 🔹 What I Learned: JavaScript executes synchronous code first, then asynchronous callbacks setTimeout does NOT store values, it stores a function (closure) Closures capture variables by reference, not by value var uses a single shared variable let creates a new variable for each iteration 🔹 The Problem I Faced: I expected this code to print 0 1 2, but it printed 3 3 3 🔹 Why It Happened: Loop finished execution first i became 3 All callbacks accessed the same variable reference 🔹 Solution: Using let instead of var creates a new binding for each iteration, giving the expected output. 💡 Key Takeaway: “Closures capture variables by reference. var shares one binding, while let creates a new binding per iteration.” #JavaScript #WebDevelopment #Frontend #NodeJS #LearningInPublic #Coding

JavaScript is simple… until it isn’t 😅 Here are a few things that confused me (and probably you too): 👉 [] + [] = "" 👉 [] + {} = "[object Object]" 👉 {} + [] = 0 And the classic: 👉 typeof null === "object" 🤯 JavaScript isn’t weird… it’s just misunderstood. Once you understand type coercion, execution context, and closures, everything starts making sense. 💡 My advice: Don’t just “use” JavaScript — understand how it works internally. What’s the most confusing JS behavior you’ve faced? 👇 #javascript #webdevelopment #frontend #programming

📌 JavaScript vs TypeScript — Quick Comparison 💻 🔹 JavaScript (JS) - Dynamic typing, no need to define variable types - Beginner-friendly with simple syntax - Runs directly in the browser or Node.js - Flexible, but can be error-prone in large projects 🔹 TypeScript (TS) - Static typing, variable types must be defined upfront - Early error detection during development - Better for type safety in large-scale applications - Compiles into JavaScript before running 🎯 Bottom Line: JavaScript is for flexibility, while TypeScript is for structure and scalability. #srothit #javascript #typescript #programming #software

JavaScript becomes a different language the moment you realize this: 👉 Functions are not just reusable blocks… they are values. And once you understand that, concepts like callbacks and higher-order functions stop feeling confusing and start feeling natural. In this video, I’ve broken it down step by step: How values behave in JavaScript How objects behave Why functions behave the same way (and why that matters) From there, everything builds logically: ✔ Passing functions as arguments ✔ Returning functions from functions ✔ What exactly a callback is ✔ What a higher-order function is ✔ How this leads to more flexible and reusable code No jargon. No unnecessary complexity. Just a clear, practical approach to a core JavaScript concept. 🎥 Watch here: https://lnkd.in/gM8ibZ6M This is Part 1 — next, we’ll explore how this shows up in real code with: setTimeout, forEach, map, filter #JavaScript #WebDevelopment #FrontendDevelopment #Programming #Coding #LearnToCode #JavaScriptDeveloper #SoftwareDevelopment #Developers #CodingJourney #TechEducation #Hosiyar #JS

Why does JavaScript show "undefined"? If you’ve seen this, you’ve already faced Hoisting. I broke it down in the simplest way possible 👇 ✔ JavaScript runs in 2 phases ✔ var is hoisted with undefined ✔ let & const are hoisted but not initialized (TDZ) 💡 Rule: Always declare variables before using them Save this for revision 📌 #javascript #webdevelopment #frontend #coding #reactjs

🚨 Most developers use JavaScript daily… But don’t actually understand how it runs 👇 👉 Call Stack — the engine behind your code execution 💡 Simple rule: JavaScript follows 👉 Last In, First Out (LIFO) Which means: The last function added → runs first 🧠 What’s really happening? • Every function call goes into the Call Stack • It executes one by one (not all at once) • Once done → it gets removed 👉 That’s why JavaScript is single-threaded ⚠️ Where things go wrong: If functions keep stacking without stopping 👇 💥 Maximum Call Stack Size Exceeded 🎯 Why this matters: ✔ Helps you debug faster ✔ Makes async JavaScript easier ✔ Builds strong fundamentals ✔ Gives you an edge in interviews 🔥 Reality: Most developers focus on syntax But real growth comes from understanding execution 💬 Next time your code behaves weirdly… Don’t guess 👉 Think about the Call Stack #JavaScript #WebDevelopment #Frontend #Coding #Developers #LearnInPublic

🚀 JavaScript vs TypeScript — Which one do you prefer? Here’s a simple breakdown 👇 🟡 JavaScript ✔ Easy to start ✔ Flexible ❗ But errors can show up at runtime 🔵 TypeScript ✔ Type safety ✔ Better tooling & autocompletion ✔ Catches errors early (before running code) 💡 In short: JavaScript = Fast & flexible TypeScript = Safe & scalable 👉 If you’re building small projects, JavaScript works great. 👉 For large applications, TypeScript is a game changer. 💬 What do you use in your projects — JS or TS? #JavaScript #TypeScript #React #Frontend #Programming #SoftwareEngineering

Work in progress 💻 Deep in the code today, building out new functionality for Scrimba Advance JavaScript. Sometimes the best commits are the ones that say "promise" twice because that's exactly what clean, asynchronous code delivers. Those small, focused commits? That's where the real progress happens.
