JavaScript Hoisting Explained: var, let, const

"I’m just going to say it: JavaScript Promises are hard. 🙃 I thought I had a handle on asynchronous code, but then came .then(), .catch(), and the logic of resolve vs reject. It’s one of those topics where you think you’ve got it, and then one unhandled rejection reminds you that you don't. Learning to code isn't always 'eureka' moments; sometimes it's just sitting with the frustration until it clicks. To my fellow devs—what was the one JS concept that finally made the lightbulb go off for you? #Javascript #WebDevelopment #CodingLife #LearnToCode"

Day 5 of 30: Tracking time with JavaScript! For today’s #30DaysOfJavaScript challenge, I built a real-time Digital Clock. This project was a great way to dive into how the browser handles time and asynchronous updates. Check it out here: https://lnkd.in/dc3aAeBt Key Technical Highlights: => Real-time: Used setInterval() to keep the clock ticking. => Localized: Used .toLocaleString() to ensure the format matches the user's location. => Building small every day leads to big results. On to Day 6! #WebDevelopment #JavaScript #CodingChallenge #Netlify #BuildInPublic #FrontEndDev

JavaScript is single-threaded. So how does it run setTimeout, Promises, and await without blocking everything? The answer is the event loop. But most explanations make it sound more complicated than it actually is. Async in JavaScript isn’t magic. It’s just a predictable system of queues: • Call Stack • Microtask Queue • Macrotask Queue • Rendering cycle Once you understand how these queues run, the execution order suddenly makes sense. No more “Why did this run first?” moments. I broke the whole concept down visually in this carousel. If async has ever confused you while debugging Save this post, you’ll want it later.

Day 7 of “Js in bits series – (Datatypes - undefined)” Key ideas covered in the article: 🔹 What undefined actually represents 🔹 When JavaScript automatically assigns undefined 🔹 Common scenarios where developers encounter it 🔹 The difference between undefined and null 👉 https://lnkd.in/gSN7MqSY #javascript #webdevelopment #frontend #softwareengineering #coding #learning

🚀 Promises in JavaScript — Simplified Handling asynchronous operations in JavaScript can get messy… especially with callback hell. That’s where Promises come in. 👉 A Promise is an object that represents a future value — something that will be available after an async operation completes. It has 3 states: 1️⃣ Pending → Initial state (waiting) 2️⃣ Fulfilled → Operation successful 3️⃣ Rejected → Operation failed 💡 Promises make async code cleaner, readable, and easier to manage compared to callbacks. Mastering this is a must for every JavaScript developer 💯 #JavaScript #WebDevelopment #FrontendDevelopment #AsyncProgramming #Coding

Day 27 of my 28-day coding challenge was focused on practical JavaScript implementation. Here’s what I worked on today 👇 🛒 JavaScript Practice Built an Add to Cart functionality using pure JavaScript Worked on: - Handling button click events - Updating cart state dynamically - Managing quantities - Reflecting changes in the UI in real time - This felt like a real-world feature rather than just a practice exercise. Day 27 takeaway: Building real features strengthens logic, state handling, and DOM manipulation skills. 1 day to go. Staying consistent. #28DaysChallenge #Day27 #JavaScript #Frontend #Ecommerce #DOM #BuildInPublic #LearningInPublic #CodingJourney

🌀 Recursion in JavaScript Recursion is a technique where a function calls itself to solve a problem. 👉 It works by breaking a problem into smaller parts 👉 Each call handles a smaller input 👉 It stops when it reaches a base case 💡 Key Concepts: • Base Case → Stops the recursion • Recursive Case → Calls the function again ⚠️ Important: Without a base case, recursion will cause infinite calls and crash the program. 🔥 Key Takeaway: Solve a small part and let recursion handle the rest. #javascript #webdevelopment #frontend #coding #100DaysOfCode

60 Days of JavaScript: Day 13 ✅ Another day, another step closer to JavaScript fluency. Today's focus: DOM Selection Methods We covered: ⚡ Dot syntax – understanding how objects talk ⚡ getElementById – precise element targeting ⚡ getElementsByTagName – group selection ⚡ querySelector & querySelectorAll – modern, flexible, powerful Slowly but surely, the DOM is opening up. Can't wait to start MANIPULATING what we select! Every day feels like adding another tool to the belt. The foundation is getting stronger. #JavaScript #CodingJourney #WebDevelopment #60DayChallenge #Frontend

🚀 From Confused to Confident in JavaScript Every developer starts with excitement. At first, JavaScript feels easy — let, const, loops, functions… all simple. Then Hoisting appears. Why is the variable undefined even before it’s assigned? Then comes Closure. How does a function remember variables even after it has finished executing? Three days gone. Still confused. And then… Async JavaScript. Nested callbacks. Callback Hell. Frustration. But quitting wasn’t an option. Promises were learned. Async/Await was understood. The console became a best friend. Small projects were built. And one day, the realization happened: JavaScript isn’t hard. Clarity just takes time. Six months later, the same developer confidently explains: Execution Context. Closure. Event Loop. Async/Await. 💡 Moral Every developer struggles. The ones who don’t stop… are the ones who grow. #MERN #JavaScript #WebDevelopment #Frontend #MERNStack #CodingJourney

Our new YouTube video from the Intermediate JavaScript Series is now live! In this one, we break down Execution Contexts, Thread of Execution, and Stack Memory in a simple and practical way.
