React JSX Attributes and Properties

♻️ What is refactoring? It seems obvious, right? "Refactoring is the process of restructuring existing code to improve its readability, maintainability, or performance without changing its external behavior." Thanks, Chad. Improve its readability… what seems readable today is pure crap tomorrow. Do you have any guidelines for #NextJS projects? Or will it improve by just choosing one thing, sticking to it, and improving the process of improvement ( 😄 ) over time? How do I make sure that my adjustments are still relevant in a month and not just a waste of time and money? How do you approach refactoring in your #React or #NextJS projects? Let me know in the comments! #CleanCodeSolutions #WebDevelopment #JavaScript #TypeScript

🚀 JSX Comments (React Development) To add comments within JSX, you need to use JavaScript-style comments wrapped in curly braces: `{/* This is a comment */}`. Regular HTML comments (``) will not work correctly inside JSX. Using the correct comment syntax ensures that your comments are properly parsed and do not interfere with the rendering of your component. This is crucial for documenting your code and providing explanations for other developers. #ReactJS #Frontend #WebDev #React #professional #career #development

The React pattern that eliminated 80% of my useEffect calls Most useEffect calls are just bad data derivation. Here is the derived state pattern that cleaned up years of accumulated complexity in my React components.

🚀 Array Methods: splice and slice (JavaScript) The `splice()` method modifies an array by removing or replacing existing elements and/or adding new elements in place. It takes the starting index and the number of elements to remove as arguments, and optionally, new elements to insert. The `slice()` method returns a shallow copy of a portion of an array into a new array object selected from start to end (end not included) where start and end represent the index of items in that array. `slice()` does not modify the original array. #JavaScript #WebDev #Frontend #JS #professional #career #development

https://lnkd.in/d-DiKiMf - Simple tools are often the hardest to get right. As a Frontend Engineer specializing in Next.js 15 and TypeScript, I thought building a Word Count Calculator would be a weekend breeze. I was wrong. Calculating words isn't just about splitting strings by spaces; it’s about handling double spaces, tabs, and non-breaking characters. I remember a student emailing me because their 10,000-word essay was showing different counts on different platforms. That’s when I pivoted to using Vitest and Bun to test against thousands of edge cases and international symbols. I used Cursor to pair-program the regex logic, ensuring it stays performant as you type. With Tailwind CSS for a clean UI and Vercel for instant deployment, the tool is now faster than ever. Building 300+ tools for my platform has taught me that the modern baseline for quality is always moving higher. What’s the most frustrating edge case you’ve ever had to debug in a 'simple' feature? 🚀 💻 🧠 ⚡ 📝 ✅ 🛠️ 📈 #WordCountCalculator #FrontendEngineer #TypeScript #NextJS #WebDevelopment #CodingLife #BuildingInPublic #ReactJS #TailwindCSS #SoftwareEngineering #Vercel #WebPerf #DevCommunity #SaaS #CleanCode

𝟱 𝗡𝗲𝘅𝘁.𝗷𝘀 𝗙𝗲𝗮𝘁𝘂𝗿𝗲𝘀 𝗧𝗵𝗮𝘁 𝗜𝗻𝘀𝘁𝗮𝗻𝘁𝗹𝘆 𝗜𝗺𝗽𝗿𝗼𝘃𝗲𝗱 𝗠𝘆 𝗪𝗼𝗿𝗸𝗳𝗹𝗼𝘄 I didn’t switch to 𝗡𝗲𝘅𝘁.𝗷𝘀 just to follow the trend. I switched because my workflow was getting messy. Here’s what actually made a difference: • 𝗔𝗽𝗽 𝗥𝗼𝘂𝘁𝗲𝗿 — cleaner structure, less confusion • 𝗦𝗲𝗿𝘃𝗲𝗿 𝗖𝗼𝗺𝗽𝗼𝗻𝗲𝗻𝘁𝘀 — less client-side JS, better performance • 𝗕𝘂𝗶𝗹𝘁-𝗶𝗻 𝗔𝗣𝗜 𝗿𝗼𝘂𝘁𝗲𝘀 — no need for a separate backend for small projects • 𝗜𝗺𝗮𝗴𝗲 𝗢𝗽𝘁𝗶𝗺𝗶𝘇𝗮𝘁𝗶𝗼𝗻 — performance boost without extra effort • 𝗙𝗶𝗹𝗲-𝗯𝗮𝘀𝗲𝗱 𝗿𝗼𝘂𝘁𝗶𝗻𝗴 — faster development, zero routing headaches What this really means is simple: I spend less time 𝗰𝗼𝗻𝗳𝗶𝗴𝘂𝗿𝗶𝗻𝗴… and more time 𝗯𝘂𝗶𝗹𝗱𝗶𝗻𝗴. If you’re still juggling multiple tools to get things done, 𝗡𝗲𝘅𝘁.𝗷𝘀 might quietly simplify your entire setup. Curious—what’s one feature you can’t live without? #NextJS #ReactJS #JavaScript #WebDevelopment #FrontendDevelopment #SoftwareEngineering #DevCommunity #BuildInPublic #ProgrammingLife #TechCareer

Same same… but different: #React edition 👀 I learn the term #diffing few days ago. Now today I learned a new term called #Reconciliation, and I got confused. First I thought both were the same but they're not. Let's understand it in a simple way...... 🔄 Reconciliation: --> This is the entire process through which React updates the UI. 1. React creates a new virtual #DOM. 2. Compares it with the previous one. 3. Decide what needs to change. 4. Updates that part in the real DOM. 🟧 Diffing: --> This is just one step inside reconciliation. React compares old and new virtual DOM and finds what actually changed (The Comparison step) 💭 Imagine editing a document: |++| Reconciliation = entire editing process |++| Diffing = finding differences between old vs new version Did you also think both were the same? 😄 Or was it just me? #ReactJS #ReactDeveloper #FrontendDevelopment #JavaScript #WebDevelopment #MERNStack #CodingJourney #LearnToCode #SoftwareDevelopment
