Built a Tab Switching feature with JavaScript for better UI interaction.

🎯 A Little Story About JavaScript Events While working on a UI feature recently, I was thinking about how neatly JavaScript handles user interactions — especially through event flow. Imagine this 👇 You click a button inside a card component. The click first triggers on the button... but somehow, the parent card also reacts. That’s not magic — that’s Event Bubbling in action. In bubbling, the event starts at the target element and travels up through all its ancestors until it reaches the top of the DOM. There’s also the opposite path — Event Capturing — where the event moves down from the root to the target. You can enable this phase using: element.addEventListener("click", handler, true); And sometimes, you just want that click to stay right where it happened — no parents involved. That’s when event.stopPropagation() steps in to save the day ✋ Understanding how events travel through the DOM makes handling complex interfaces so much smoother. It’s one of those core concepts that quietly powers every interactive web experience we build. #JavaScript #Frontend #WebDevelopment #Coding #TIL

🚀 #Day 3 Understanding JavaScript Event Loop & React useEffect Timing Today, I took a deep dive into one of the most powerful — yet often confusing — topics in JavaScript: the Event Loop 🔁 At first, it looked complex. But once I started writing small examples and observing outputs step-by-step, everything became crystal clear 💡 🔍 What I learned: 🧠 The Event Loop JavaScript is a single-threaded language — meaning it can execute only one task at a time. But thanks to the Event Loop, it can still handle asynchronous operations (like setTimeout, fetch, or Promise) efficiently without blocking the main thread. Here’s how it works 👇 1️⃣ Call Stack — Executes synchronous code line by line. 2️⃣ Web APIs — Handles async tasks (like timers, fetch). 3️⃣ Microtask Queue — Holds resolved Promises and async callbacks. 4️⃣ Callback Queue — Stores setTimeout, setInterval callbacks. The Event Loop continuously checks: “Is the call stack empty? If yes, then push the next task from the microtask queue — and then from the callback queue.” That’s how JavaScript manages async code without breaking the flow ⚡ ⚛️ In React: useEffect() runs after the component renders, and async tasks inside it still follow the Event Loop rules. That’s why: console.log("Start"); setTimeout(() => console.log("Timeout"), 0); Promise.resolve().then(() => console.log("Promise")); console.log("End"); Output: Start → End → Promise → Timeout ✅ 💬 Takeaway: Once you understand the Event Loop, async code and React effects start making perfect sense! #JavaScript #ReactJS #FrontendDevelopment #EventLoop #AsyncProgramming #WebDevelopment #ReactHooks #LearningInPublic #DevelopersJourney #CodeBetter

🚀 Mastering Async JavaScript: Promises vs Async/Await Async operations are everywhere in frontend — API calls, data fetching, animations, etc. I’ve broken down how Promises and async/await work, with real code examples and a clear comparison to help you understand: ✅ When to use .then() chaining ✅ Why async/await is cleaner for multiple async steps ✅ Common pitfalls and debugging tips 💡 The goal: write more readable, maintainable, and modern async code in JavaScript. If you’ve ever dealt with nested Promises or callback chains, this guide will make your async logic much easier to follow. ⬇️ Check out the slides to learn visually how both approaches work and when to use each effectively. #JavaScript #FrontendDevelopment #ReactJS #AsyncAwait #Promises #WebDevelopment #NextJS #TechLearning

🚀 Web Dev Day 32: Mastering JavaScript Events — Making the Web Come Alive! ✨ Today’s session was all about DOM Events — the real magic behind user interaction in web development. Every click, scroll, or keypress you make triggers an event — and learning how to handle them properly separates a coder from a developer. 💡 🔹 Part 1: The Fundamentals of Events What is a DOM Event? Think of it like a doorbell — when a user interacts, JavaScript gets notified. 🔔 The 3 Core Components: Target: The element that triggers the event. Event Type: The kind of interaction (e.g., click, input, mouseover). Handler: The function that runs when the event occurs. Modern Approach: Use addEventListener() — it’s flexible, cleaner, and supports multiple listeners. Why Avoid onclick: It mixes HTML and JS, breaking Separation of Concerns. The Event Object: A built-in “information packet” containing details like mouse position, key pressed, and more. 🔹 Part 2: The Three Phases of an Event Event Bubbling: Events rise from the deepest element (child) up to its ancestors (parent → document). Event Capturing: The reverse — events travel from the top (document) down to the target. Visualizing Flow: Understanding how the browser processes events step by step helps debug like a pro. Control the Flow: Use event.stopPropagation() to prevent events from bubbling further when needed. 🧠 🔹 Part 3: The Event Delegation Pattern What Is It? Instead of adding listeners to multiple elements, attach one listener to a parent element. Why It’s Powerful: Better performance and easier management, especially for dynamic content. Key Tools: event.target → The actual element clicked. event.currentTarget → The element the listener is attached to. Real-World Example: Building an interactive to-do list where all items respond to clicks — with just one event listener! ✅ 🎯 Takeaway: Events are the heartbeat of interactive web apps. Understanding how they flow, bubble, and delegate gives you total control over your UI. #Day32 #JavaScript #WebDevelopment #Frontend #DOMEvents #EventHandling #CodingJourney #LearnInPublic #JS #Programming #CoderArmy #RohitNegi

95% of developers can’t clearly explain how JavaScript executes code. If you don’t understand the Event Loop, you don’t truly grasp JS. ➤ Complete JavaScript Event Loop Breakdown 𝗧𝗵𝗲 𝗖𝗮𝗹𝗹 𝗦𝘁𝗮𝗰𝗸: Last-In-First-Out (LIFO) structure Stores currently running function contexts Functions are pushed when called Functions are popped when finished JavaScript runs on a single thread 𝗪𝗲𝗯 𝗔𝗣𝗜𝘀 (𝗕𝗿𝗼𝘄𝘀𝗲𝗿-𝗦𝘂𝗽𝗽𝗹𝗶𝗲𝗱): 6. setTimeout / setInterval – timer APIs 7. fetch / XMLHttpRequest – network requests 8. DOM events – click, scroll, keyboard 9. Promise resolution handled externally 10. All of these run outside the JS engine 𝗧𝗵𝗲 𝗤𝘂𝗲𝘂𝗲𝘀: 11. Callback Queue (Macrotask): setTimeout, DOM events, I/O callbacks 12. Microtask Queue: Promise.then, queueMicrotask, MutationObserver 13. Animation Frame Queue: requestAnimationFrame 𝗧𝗵𝗲 𝗘𝘃𝗲𝗻𝘁 𝗟𝗼𝗼𝗽 𝗣𝗿𝗼𝗰𝗲𝘀𝘀: 14. Check if call stack is empty 15. If not, continue executing current code 16. If empty, run all microtasks first 17. Render updates if needed (60fps target) 18. Execute one macrotask from callback queue 19. Repeat the process endlessly 𝗣𝗿𝗶𝗼𝗿𝗶𝘁𝘆 𝗢𝗿𝗱𝗲𝗿: 22. Synchronous code executes immediately 23. Microtasks (Promises, queueMicrotask) 24. Animation frames (requestAnimationFrame) 25. Macrotasks (setTimeout, setInterval) 𝗖𝗼𝗺𝗺𝗼𝗻 𝗠𝗶𝘀𝘂𝗻𝗱𝗲𝗿𝘀𝘁𝗮𝗻𝗱𝗶𝗻𝗴𝘀: 26. setTimeout(fn, 0) is not instant 27. Promises resolve asynchronously 28. async/await is just Promise syntax sugar 29. Event loop never stops 30. Long-running code blocks everything 𝗥𝗲𝗮𝗹-𝗪𝗼𝗿𝗹𝗱 𝗜𝗺𝗽𝗹𝗶𝗰𝗮𝘁𝗶𝗼𝗻𝘀: 31. Heavy computation can block UI updates 32. Use Web Workers for CPU-intensive tasks 33. Split large tasks with setTimeout or requestIdleCallback 34. Promises always run before macrotasks 35. Understanding this helps debug async issues and race conditions Master the Event Loop and most JavaScript mysteries vanish. #JavaScript #EventLoop #AsyncJS #WebDevelopment #FrontendDev #CodingTips #Programming #Microtasks #Macrotasks #JS #DeveloperLife #TechTips #AsyncProgramming
