React useCallback for Performance Optimization

💡 𝗧𝗶𝗽 𝗼𝗳 𝘁𝗵𝗲 𝗗𝗮𝘆 — 𝗥𝗲𝗮𝗰𝘁 𝗗𝗶𝗱 𝘆𝗼𝘂 𝗸𝗻𝗼𝘄? State updates in React are 𝗮𝘀𝘆𝗻𝗰𝗵𝗿𝗼𝗻𝗼𝘂𝘀 𝗮𝗻𝗱 𝗯𝗮𝘁𝗰𝗵𝗲𝗱 — so logging state immediately after calling "setState" (or a state setter from "useState") will often show the old value. 🔧 𝗕𝗲𝘀𝘁 𝗽𝗿𝗮𝗰𝘁𝗶𝗰𝗲: If you need to react to a state change, use useEffect with that state as a dependency instead of relying on immediate logs. Understanding this avoids a whole class of confusing bugs. #React #ReactJS #FrontendDevelopment #JavaScript #WebDevelopment #SoftwareEngineering #CodingTips #FullstackDeveloper

Ever wondered why process.nextTick() runs before Promises in Node.js? I created a short visual to explain how nextTick and Promise queues work inside the Node.js Event Loop and why their execution order matters. Understanding this helps avoid performance issues and unexpected behavior in async code. Let me know if this was helpful 👇 #nodejs #javascript #eventloop #backend #async #webdevelopment

Still fighting JavaScript dates? Stop reinventing the wheel. These npm packages make date formatting painless 👇 1. date-fns 2. dayjs 3. luxon 4. js-joda 5. tiny-date Clean APIs. Better readability. Fewer bugs. Pick the one that fits your stack and move on faster 👉Follow Codeflare #JavaScript #npm #WebDevelopment #FrontendDev #NodeJS #DateFormatting #DevTips #CodeSmart #codeflare #codeflaretech

Optimize Re-renders with React.memo Avoid unnecessary re-renders in React functional components by using React.memo. It memoizes your component and only re-renders it when props change — great for performance! Typing in the input won’t trigger a re-render of the Child component because it’s wrapped with React.memo. Less re-render = smoother performance! #ReactJS #JavaScript #FrontendDevelopment #WebDevelopment #ReactTips #CodingTips

🚀 React Js : Understanding the useEffect Hook The useEffect hook is one of the most important features in React. It allows you to run code after a component renders. 💡 Why useEffect is important: useEffect tells React what should happen after the UI updates. It’s commonly used for tasks like fetching data, updating values, or cleaning up resources. 🧠 How it works: No dependency array → runs after every render Empty dependency array [] → runs only once With dependencies → runs when those values change ✅ Benefits of using useEffect: Cleaner code Better performance Easier to manage side effects Mastering useEffect helps you build more reliable and efficient React applications. 💪 #ReactJS #JavaScript #FrontendDevelopment #ReactHooks #WebDevelopment #Coding

Understanding State in React.js 🚀 State is the heart of a React component. It represents dynamic data that changes over time and directly controls what users see on the screen. When state updates, React automatically re-renders the component — making the UI responsive, interactive, and powerful. Learning state taught me one key lesson: 👉 UI is just a reflection of data. #ReactJS #FrontendDevelopment #WebDevelopment #LearningReact #JavaScript #ReactJS #WebDevelopment #Frontend #CodingJourney #Javascript #ReactHooks

✨ Today, I worked on strengthening my React fundamentals ✨ Worked on Props in React — understanding how to pass data between components, use destructuring, and apply default props. 🔑 Key Points I Learned: • Props are used to pass data from parent to child • Props are read-only (immutable) • They help create reusable components • Destructuring props makes code cleaner and easier to read • Default props allow setting fallback values when no prop is provided • Props can pass text, numbers, and images • React follows one-way data flow 📌 Strengthening my React fundamentals step by step 🚀 #ReactJS #ReactProps #DefaultProps #Destructuring #FrontendDevelopment #JavaScript #LearningJourney

Bun made benchmarks look exciting. Node made production boring. If speed is your only argument, you’re probably not running real systems yet. In 2026, the question won’t be “Which runtime is faster?” It will be: “Which one breaks less at 3 AM? 😄😂” Choose your runtime. But be honest about why. #NodeJS #BunJS #BackendDevelopment #SoftwareEngineering #JavaScript #RuntimeWars #TechTrends #SystemDesign #DevOpinions #BuildingInPublic
