The Great Debate: Formik or React Hook Form?  Both are industry favorites, but they offer two very different approaches to handling forms in React. While one is praised for its stability and ease of use, the other is the go-to for performance and minimal re-renders. Most developers have a strong preference, but is there really a "winner"? Which one is currently in your tech stack, and why did you choose it over the other? 👇   #ReactJS #FrontendDevelopment #WebPerformance #ProgrammingTips #Javascript

🚀 React Devs — Quick Brain Teaser! What will happen in this code? 𝗰𝗼𝗻𝘀𝘁 [𝗰𝗼𝘂𝗻𝘁, 𝘀𝗲𝘁𝗖𝗼𝘂𝗻𝘁] = 𝘂𝘀𝗲𝗦𝘁𝗮𝘁𝗲(𝟬); 𝘂𝘀𝗲𝗘𝗳𝗳𝗲𝗰𝘁(() => { 𝘀𝗲𝘁𝗖𝗼𝘂𝗻𝘁(𝟱); }); 🤔 How many times will this component re-render? 🔘 A. 1 time 🔘 B. 2 times 🔘 C. Infinite loop 🔘 D. Depends on React version 💡 Drop your reasoning in the comments — not just the answer! #ReactJS #Frontend #JavaScript #WebDevelopment #InterviewQuestions #ReactHooks

React Batching: The Subtle Bug Most Developers Miss   A quick React insight 👇  React doesn’t re-render on every state update.  It batches multiple updates together for performance. setCount(count + 1); setCount(count + 1);  You might expect +2, but it results in +1 —  because both updates use the same value. ✅ Correct approach: setCount(prev => prev + 1); setCount(prev => prev + 1);  React state updates are scheduled, not immediate --  and that’s where subtle bugs come from. #reactjs #javascript #frontend

Unpopular opinion: Most React codebases are just jQuery with extra steps. 👀 Components that do 10 things. State scattered everywhere. useEffect doing God's work. Clean React is: → One component, one job → State that lives where it belongs → Effects that actually make sense The framework isn't the problem. The habits are. #React #WebDevelopment #Frontend #CleanCode #JavaScript

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

most React developers use useCallback wrong. not because they don't understand it. because they were taught the wrong rule. the rule they heard: "wrap functions in useCallback to prevent unnecessary re-renders. the actual rule: useCallback only helps when you pass that function to a child component wrapped in React.memo or as a dependency in useEffect. that's it. useCallback doesn't prevent re-renders of the parent. it just memoizes the function reference so children don't see a "new" function every render. three questions to ask before reaching for useCallback: - is this function passed to a memoized child component? - is this function a dependency in a useEffect? - is this function expensive to recreate? if none of these just write the function normally. the best optimisation is usually the one you don't add. #reactjs #typescript #webdevelopment #buildinpublic #javascript
