Recently while working on my React Native project (with the new React Compiler), I was wondering, “Which components are actually auto-memoized by the compiler?” 🤔 Then I came across a great tip by Alberto Moedano he mentioned there’s a VS Code extension called React Compiler Marker 💡 This extension automatically highlights components that are memoized by the compiler with a ⭐ icon super helpful to visually see what’s optimized! If you’re exploring React Compiler, definitely give this a try. Small tools like this make a big difference #ReactNative #ReactCompiler #React #JavaScript #DeveloperTools #VSCode

Just React theory? Here are 3 practical components you'll actually use: 1. SearchBar with Debouncing - Optimizes API calls on user input. 2. Modal/Popup - Reusable for forms, confirmations, and details. 3. Infinite Scroll - Perfect for feeds and data-heavy lists. What's your go-to reusable component?

🚀 TypeScript Cheat Sheet: Level Up Your JavaScript Game! Hey LinkedIn fam! As a developer passionate about building robust apps, I've put together this handy TypeScript Cheat Sheet. TypeScript supercharges JavaScript with static typing, helping you catch errors early and write scalable code. Whether you're new to TS or need a quick refresher, this covers the essentials: 🔹Basics like type annotations, inference, and primitives. 🔹Typing arrays, objects, functions, and more. 🔹Unions, intersections, generics, and React integration. 🔹Tips for compilation and best practices. #TypeScript #JavaScript #WebDevelopment #CodingTips #DeveloperTools #FrontendDevelopment #ReactJS #Programming

Why Node.js Is Becoming the All-in-One Runtime Over the years, Node.js has transformed from a simple JavaScript runtime into a complete development environment. What once required dozens of third-party tools is now available natively. Here’s how far Node.js has come 1- Built-in Test Runner — no Jest or Mocha needed 2- Native Fetch API — just like the browser 3- File Watching — no more Nodemon 4- .env Support — load environment variables natively 5- WebSocket & Permission Control — real-time and secure out of the box This evolution means: Fewer dependencies Faster setup More secure and consistent apps Node.js is no longer just a runtime it’s becoming a complete platform for modern backend development. #Nodejs #JavaScript #Developers #BackendDevelopment #Tech #Programming

There are many scenarios where we need to save data to files. If you want your Node.js app to stay fast and responsive while doing so, mastering asynchronous file writes is the key. #NodeJS #AsynchronousProgramming #JavaScript #BackendDevelopment #WebDev #Coding #SoftwareEngineering #AsyncAwait

#SynchronousvsAsynchronous in JavaScript When working with JavaScript, understanding how your code executes is key 🔑 💡 Synchronous Code runs in a fixed sequence — each line waits for the previous one to finish before moving ahead. 👉 Simple, but can cause delays if one task takes longer (like an API call). ⚡ Asynchronous Here, the code doesn’t wait! It moves to the next instruction while waiting for longer tasks to complete. 👉 Keeps the app smooth and responsive — essential for real-time and UI-heavy apps. In short: 🕒 Synchronous = Step-by-step execution ⚙️ Asynchronous = Parallel-like execution #JavaScript #WebDevelopment #Coding #Async #ProgrammingConcepts #Developers #LearningEveryday

🕒 How Async/Await Changed Node.js Forever Before async/await: callback hell 😫 After async/await: readable, clean, modern code 😎 Async/await made asynchronous programming finally feel synchronous. #NodeJS #AsyncAwait #JavaScript #CleanCode #BackendTips

🚀 Why the key Prop in React Matters! That small key prop you see in React lists? It’s not optional. It helps React identify which items changed, added, or removed — allowing faster and more efficient re-renders. ⚡ ✅ Use a unique ID like key={item.id} ❌ Avoid using indexes like key={index} (can cause UI bugs) Think of key as the ID card for your components — without it, React gets confused! 😅 #ReactJS #FrontendDevelopment #JavaScript #WebDevelopment #TechTips #ReactDeveloper #Programming #Performance
