Optimize React Component Re-renders with Independent State

One mistake I made as a React developer 🚫 I used too many states unnecessarily. 👉 Solution: Use a single state object when possible Cleaner code = fewer bugs #reactjs #javascript #codingtips

Many React developers use these every day… but don’t know the difference 👀 React Router vs React Router DOM. Similar words. Expanded capabilities. Know the difference before your next React project 👇 https://lnkd.in/e-9ytRyg #React #ReactRouter #ReactJS #FrontendDevelopment #JavaScript #WebDevelopment #Syncfusion

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

useImperativeHandle is one of the most underrated React hooks. useImperativeHandle lets a parent trigger specific actions in a child component — focus, reset, open, close — without exposing internal logic. #ReactJS #ReactHooks #FrontendDevelopment #JavaScript #WebDevelopment #SoftwareEngineering #CleanCode #UIEngineering #FrontendEngineer

Beginner React Developer vs Improving Developer Beginner: • Copies code • Uses useEffect everywhere • Writes big components Improving: • Understands logic • Keeps code simple • Breaks components Difference?

Why does React feel so fast? ⚛️🚀 It’s not just about the Virtual DOM 👇 • Calculates minimal changes • Updates only what’s needed • Batches multiple updates • Avoids unnecessary re-renders 👉 Result: Faster and smoother UI In simple terms: React updates only the changed part, not the whole page. #ReactJS #FrontendDevelopment #JavaScript #WebDevelopment #MERNStack #SoftwareEngineering

you called setState twice. expected +2. got +1. both calls read the same stale count from the current render. they don't compound. they both say "set to 1." welcome to React. why it breaks: state updates don't happen immediately. they're scheduled. so count is still 0 inside your function no matter how many times you call setState. both calls read 0. both set to 1. result: 1. the Fix: use functional updates. each call gets the previous result and builds on it. The code : #reactjs #javascript #webdevelopment #buildinpublic #typescript

React Tip: Use Functional Updates When new state depends on previous state: javascript // Wrong way setCount(count + 1); // Right way setCount(prevCount => prevCount + 1); Why? React batches updates. Functional updates ensure you always have the latest value. #ReactJS #FrontendDeveloper #CodingTips

React 19.2 introduces the <Activity> component, which eliminates the issue of losing form state when switching tabs. This update encourages developers to stop unmounting components, offering a new approach to handle state effectively. #ReactJS #Javascript #FrontendDeveloper #React19 #WebPerformance #CodingTips #SoftwareArchitecture #StateManagement #JS #ProgrammingLife

most React developers don't know why their promises break silently. they wrap everything in .catch() and wonder why errors still slip through. the problem: - .catch() only catches errors up to that point - errors after the chain slip through unhandled - processData() throws but catch doesn't see it the fix : check response status: and one rule: proper error boundaries. check status. validate data. catch at the end. #reactjs #typescript #webdevelopment #buildinpublic #javascript
