Improved NodeJS Performance with Async Code Optimization

React Query changed how I think about state — and I have not used Redux since The server state vs client state distinction that React Query makes explicit replaced my need for Redux entirely. Here is the mental model shift. Full breakdown (7 min read) → https://lnkd.in/gcUhHrV2 #ReactJS #Frontend #JavaScript #TypeScript #WebDev #UIEngineering

The React pattern that eliminated 80% of my useEffect calls Most useEffect calls are just bad data derivation. Here is the derived state pattern that cleaned up years of accumulated complexity in my React components.

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.

0ms Delay... but what about the extra arguments? 🧐 Most developers know setTimeout(callback, delay), but did you know you can pass arguments directly into the callback? #JavaScript #WebDevelopment #CodingQuiz #SoftwareEngineering #FrontendTips

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
