Re-rendering your entire component tree on every click? useCallback can fix that. In React, functions are recreated on every render — causing child components to re-render unnecessarily. useCallback memoizes your function, so it only changes when dependencies update. Example: Passing a search handler to a child? Wrap it in useCallback to prevent wasted renders. Real impact: In my Chat App, using useCallback for message handlers reduced lag by 40% during rapid typing. Have you ever noticed performance issues in React apps? Which optimization hook do you reach for first — useMemo or useCallback #ReactJS #FullStackDeveloper #WebDevelopment #PerformanceOptimization #JavaScriptTips #CodingLife

CI/CD pipelines definitely increase the lifespan and QoL of developers. I've just successfully integrated two #GitHubActions workflows that build and upload one of my #Flutter apps, utilizing the 2,000 free minutes you get from GitHub! The result? Every time I tag a new release on GitHub, it automatically triggers a build that lands directly in the Google Play Console and App Store Connect. No more manual Flutter builds and uploads. It feels great to have the same "push-to-deploy" in mobile that we've enjoyed in web for years. #CICD #MobileDev
