React Code Review Mistakes: useEffect, Memoization, Error Boundaries, Props Drilling, Code Splitting

Javascript concept: var vs let vs const I used var everywhere when I started learning JavaScript… Everything worked… until it didn’t. var a = 10; let b = 20; const c = 30; Then I learned: var ignores block scope ❌ let respects it ✅ const prevents reassignment 🔒 💡 Now my rule: → Use const by default → Use let only when needed #JavaScript #WebDevelopment #Frontend #Coding

💡 Built a simple interactive Counter using JavaScript! Features include: Increment & Decrement Reset Save & Load A small project, created for JavaScript practice, and it helped me strengthen my concept in DOM manipulation, event handling, and local storage. #JavaScript #WebDevelopment #Coding #Projects #JSPractice

Just published a new article on writing flexible code without losing type safety with TypeScript generics. A practical guide to building reusable abstractions while keeping strong, predictable types. 💬 Thoughts?

"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"

I broke my own rule today… and it paid off. I usually avoid adding new dependencies. But I needed faster validation for a complex form. Instead of reinventing everything, I used a lightweight validation helper. Saved time. Reduced bugs. Sometimes “don’t add libraries” becomes a limitation. The real rule should be: 👉 Add dependencies intentionally, not emotionally. Balance matters. Do you prefer building from scratch or using libraries? #webdev #javascript #productivity

Built a small Dynamic List Creator using JavaScript DOM. Users can add, edit, and delete items. Simple project, but helped me understand how to create and manage elements dynamically. Learning with Chai Aur Code cohort ☕ #JavaScript #DOM #WebDev #Frontend #ChaiCode

🌀 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

🚀 Day 6 of #30DaysOfJavaScript Today I built a Random Password Generator using JavaScript. This project generates a secure random password and also allows users to copy it easily. 🔹 Features ✔ Generate random strong password ✔ Copy password to clipboard ✔ Clean and simple UI 🛠 Tech Used HTML CSS JavaScript 🔗 Live Demo: https://lnkd.in/gvMGMfgr 🔗 GitHub Repository: https://lnkd.in/gxigBsYp I’m improving my JavaScript skills by building projects every day. More projects coming soon 🚀 #javascript #webdevelopment #frontenddevelopment #coding #100daysofcode

Day 44 of showing up, and consistency is starting to compound 🚀 Today’s challenge focused on counting digit occurrences in squared numbers—a simple concept that really tests attention to detail and iteration logic. 💡 Breaking the problem down into smaller steps made it much easier to handle and debug. What stood out is how even basic loops and string conversions can build strong problem-solving foundations when used correctly. 🔍 The real win? Staying consistent and improving a little every single day. 📈 On to the next challenge. #100DaysOfCode #CodingJourney #JavaScript #ProblemSolving #Consistency #LearningInPublic #DeveloperGrowth

Event Delegation lets you handle multiple events using a single parent listener. Instead of attaching listeners to each child element, you take advantage of event bubbling to manage everything efficiently. This approach is especially useful when working with dynamic content like todo lists, tables, or menus — where elements are added or removed frequently.
