Developer Growth Through Consistent Effort

🚀 Day 934 of #1000DaysOfCode ✨ State vs Props in React — Clear & Practical Difference If you’re learning React, one of the first concepts that can feel confusing is State vs Props. In today’s post, I’ve explained the difference between state and props in React in a simple and practical way. You’ll understand how data flows between components, when to use state, and when props are the right choice. Mastering this distinction is crucial for building predictable and well-structured React applications. 👇 What confused you more when you started with React — state or props? #Day934 #learningoftheday #1000daysofcodingchallenge #FrontendDevelopment #WebDevelopment #JavaScript #React #Next #CodingCommunity

90% of developers get this wrong. Let’s see if you’re in the 10%. What does this code print? let a = 10; { console.log(a); let a = 20; } Comment ONLY ONE answer: A) 10 B) 20 C) ReferenceError D) undefined No googling. No running it. Just reasoning. Understanding scope and the Temporal Dead Zone is what separates memorization from mastery.

🚀 React 19 just made our code cleaner! Did you know forwardRef is no longer needed in React 19? ✅ ref is now just a regular prop — no wrapper, no extra imports, no boilerplate! I recorded a short video breaking it down with a real example — triggering a Child button from a Parent using ref. 🎥 Watch the video to see it in action 💻 Code is live on my GitHub — link in comments! #React #React19 #JavaScript #Frontend #WebDevelopment #Programming #100DaysOfCode Small change, big improvement in developer experience. Love where React is heading! 💙

Javascript challenge! let a = 10; let b = 20; [a, b] = [b, a]; console.log(a, b); Drop your answer in the comments #JavaScript #CodingChallenge #WebDevelopment #FrontendDeveloper #LearnToCode

🚀 30 Days of JavaScript – Day 10 Today I built a small logical puzzle game called Bulls & Cows. The program generates a secret number and the player must guess it. After each guess, the program gives hints using Bulls (correct digit & position) and Cows (correct digit but wrong position). 🧠 Concepts Used: • loops • string indexing • conditional logic • problem-solving approach 🎥 Demo below 👇 Full source code in the comments. #JavaScript #CodingChallenge #ProblemSolving #WebDevelopment #LearningJavaScript

JavaScript Closures: Your Code's Secret Memory Keeper! 🤫 Ever wonder how functions remember things even after they're done running? It's not magic, it's CLOSURES! ✨ Level up your JavaScript game with Closures! 🚀 This powerful concept lets functions "remember" their environment, creating private variables and stateful functions. Perfect for building things like counters, private data, and more! Get ready to impress your tech crush. 😉 #JavaScript #Closures #WebDev #CodingTips #FrontendDeveloper #TechInfluencer #JS ⚙️ Built using my automated code-to-image server and n8n. If you spot anything improvable, I’d love your feedback.

⚡ Microtask vs Macrotask Why does Promise.then() run before setTimeout() — even when the delay is 0 ms? Most developers think 0 ms means “immediately”. But JavaScript has a different rule. Here’s what actually happens: 1️⃣ Call Stack executes 2️⃣ All Microtasks run 3️⃣ One Macrotask runs 4️⃣ Repeat And since Promises go to the Microtask Queue, they execute BEFORE Macrotasks like setTimeout(). That’s why: Promise > setTimeout Understanding this small detail can completely change how you debug async code. 💬 Quick Question: What will log first? setTimeout(() => console.log("A"), 0) Promise.resolve().then(() => console.log("B")) Comment your answer 👇 #JavaScript #WebDevelopment #FrontendDeveloper #AsyncProgramming #EventLoop #KeepCoding

Predict the output: function test() { console.log(a); var a = 10; } test(); Output: undefined Why? Because of hoisting. JavaScript rewrites it internally as: function test() { var a; console.log(a); a = 10; } Only declaration is hoisted. Not initialization. Now try with let: function test() { console.log(a); let a = 10; } This throws an error. Because let has temporal dead zone. Understanding hoisting prevents subtle bugs. #javascript #frontend #webdevelopment #programming

Web Dev Cohort 2026 – T-Class | JS in Action ☕🚀 In today’s session, we learned about focused learning and discussed the best learning approach with Akash Kadlag sir. We also went through how to tackle problems step by step, and solved a few JS assignment problems live during the session. That’s all about today’s session — small guidance, but very useful for building the right problem-solving mindset. 🚀 #ChaiAurCohort #chaiaurcode #webdevcohort2026 #javascript #learninginpublic

JS is single-threaded. But handles async? The secret → The Event Loop. Call Stack = running NOW Callback Queue = waiting Event Loop = when stack is empty, push from queue That's it. Not magic. Just clever delegation. 🔄 #JavaScript #EventLoop #WebDev #LearnToCode
