React Native onEndReached Issue and Solution

💡 𝗧𝗶𝗽 𝗼𝗳 𝘁𝗵𝗲 𝗗𝗮𝘆 — 𝗥𝗲𝗮𝗰𝘁 𝗡𝗮𝘁𝗶𝘃𝗲 𝗗𝗶𝗱 𝘆𝗼𝘂 𝗸𝗻𝗼𝘄? In React Native, "ScrollView" 𝗿𝗲𝗻𝗱𝗲𝗿𝘀 𝙖𝙡𝙡 𝗶𝘁𝘀 𝗰𝗵𝗶𝗹𝗱𝗿𝗲𝗻 𝗮𝘁 𝗼𝗻𝗰𝗲, while "FlatList" renders items 𝗹𝗮𝘇𝗶𝗹𝘆 as they appear on screen. 🔧 Why this matters: - "ScrollView" is fine for 𝘀𝗺𝗮𝗹𝗹, 𝘀𝘁𝗮𝘁𝗶𝗰 𝗰𝗼𝗻𝘁𝗲𝗻𝘁 - But for long lists, it can cause 𝗽𝗲𝗿𝗳𝗼𝗿𝗺𝗮𝗻𝗰𝗲 𝗶𝘀𝘀𝘂𝗲𝘀 𝗮𝗻𝗱 𝗺𝗲𝗺𝗼𝗿𝘆 𝗯𝗹𝗼𝗮𝘁 - "FlatList" is optimized for large datasets with better performance 𝗥𝘂𝗹𝗲 𝗼𝗳 𝘁𝗵𝘂𝗺𝗯: Small list → "ScrollView" Large/dynamic list → "FlatList" Choosing the right component = better performance. #ReactNative #MobileDevelopment #PerformanceOptimization #JavaScript #AppDevelopment #SoftwareEngineering #CodingTips #React #FullstackDeveloper

React wraps native events in a 𝗦𝘆𝗻𝘁𝗵𝗲𝘁𝗶𝗰𝗘𝘃𝗲𝗻𝘁 to ensure consistent behavior across browsers. 🔧 𝗪𝗵𝘆 𝘁𝗵𝗶𝘀 𝗺𝗮𝘁𝘁𝗲𝗿𝘀: - You get a unified API regardless of the browser - But the event object may be 𝗽𝗼𝗼𝗹𝗲𝗱 𝗮𝗻𝗱 𝗿𝗲𝘂𝘀𝗲𝗱 𝗕𝗲𝘀𝘁 𝗽𝗿𝗮𝗰𝘁𝗶𝗰𝗲: If you need to access the event asynchronously, store needed values immediately.

Avoid Unnecessary Re-renders in React Many React applications become slow not because of bad logic, but because of unnecessary re-renders. To understand this better, I prepared a short PDF explaining: -Memoization in React -useMemo vs useCallback vs React.memo -When optimization is useful -When memoization actually makes performance worse -Best practices for real projects Always remember: Measure first, optimize later. Sharing this guide for developers who want to improve React performance. #ReactJS #FrontendDeveloper #CleanCode #PerformanceOptimization #JavaScript

💡 𝗧𝗶𝗽 𝗼𝗳 𝘁𝗵𝗲 𝗗𝗮𝘆 — 𝗥𝗲𝗮𝗰𝘁 𝗡𝗮𝘁𝗶𝘃𝗲 (𝗣𝗲𝗿𝗳𝗼𝗿𝗺𝗮𝗻𝗰𝗲) 𝗗𝗶𝗱 𝘆𝗼𝘂 𝗸𝗻𝗼𝘄? In React Native, 𝗿𝗲-𝗿𝗲𝗻𝗱𝗲𝗿𝘀 𝗰𝗮𝗻 𝗰𝗮𝘀𝗰𝗮𝗱𝗲 𝘁𝗵𝗿𝗼𝘂𝗴𝗵 𝘆𝗼𝘂𝗿 𝗰𝗼𝗺𝗽𝗼𝗻𝗲𝗻𝘁 𝘁𝗿𝗲𝗲 𝗶𝗳 𝗽𝗿𝗼𝗽𝘀 𝗮𝗿𝗲 𝘂𝗻𝘀𝘁𝗮𝗯𝗹𝗲. Passing new object/array/function references on every render can cause child components to re-render—even when nothing actually changed. 🔧 𝗕𝗲𝘀𝘁 𝗽𝗿𝗮𝗰𝘁𝗶𝗰𝗲: - Memoize values with "useMemo" - Memoize functions with "useCallback" - Use "React.memo" for pure components Stable references = fewer unnecessary renders. #ReactNative #MobileDevelopment #PerformanceOptimization #JavaScript #AppDevelopment #SoftwareEngineering #CodingTips #React #FullstackDeveloper

Most beginners get stuck in "Frontend Land" or "Backend Island." The real magic happens in the middle. Connecting your React UI to a live Express API is the defining moment of a Junior Developer's journey. Check out the carousel below to see exactly how to bridge the gap using the native Fetch API. #WebDevelopment #MERNstack #JavaScript #CareerGrowth #ReactJS

🧩 Importance of Components in React Native Components are the building blocks of any React Native application. Instead of writing everything in one file, we break UI into reusable components. ✔ Reusable code ✔ Cleaner structure ✔ Easy to maintain ✔ Better scalability A well-structured component system makes development faster and more efficient. Are you building reusable components or repeating code? 🤔 #ReactNative #JavaScript #MobileDevelopment #CleanCode #CodingTips 🚀

This means passing them as props can trigger unnecessary re-renders in child components. 🔧 𝗕𝗲𝘀𝘁 𝗽𝗿𝗮𝗰𝘁𝗶𝗰𝗲: - Use "useCallback" to memoize functions when passing them down - Only do this when necessary (e.g., with "React.memo" or dependency arrays) Not every function needs memoization—but knowing when it matters is key. #React #ReactJS #FrontendDevelopment #JavaScript #WebDevelopment #PerformanceOptimization #SoftwareEngineering #CodingTips #FullstackDeveloper

🚀 Day 2 — React Hooks Explained! Hooks = special functions that let you use state & lifecycle in functional components. useState → Manages State & handles Value Changes useEffect → Runs side effects like API calls, timers & DOM updates after every render Saving this series?

We all have seen the tutorials claiming that you can absolutely ignore a separate backend while Next.js takes care of everything since it has API routes. But where's the line? Should you never learn Express or NestJS or Laravel or Any backend if Next.js claims so. There are always tradeoffs between technologies and it's exactly why you should never think of one as a replacement for others. Let me know what you think. #nextjs #backenddevelopment #webdevelopment #javascript
