Tired of stale closures in your useEffect? React's useEffectEvent is here to save the day! It lets you read the latest state inside an effect without adding it to the dependency array, eliminating clunky useRef workarounds and unnecessary re-renders.

React introduces Actions to handle async form logic with less code. const [state, action, isPending] = useActionState( async () => loginUser(), null ); <form action={action}> <button disabled={isPending}>Login</button> </form> - Built-in loading state - Cleaner async handling - Less boilerplate A small feature, but a big improvement for form handling. #React #Frontend #JavaScript #WebDev #ReactJS

One small thing that improved my React code quality After working with React.js for a few years, I realized that most problems don’t come from React itself — they come from how we structure our code. What helped me the most: • Breaking UI into small, reusable components • Keeping state as local as possible • Avoiding unnecessary re-renders • Writing readable code for my future self Simple changes, but they make a big difference in real projects. #ReactJS #FrontendDevelopment #JavaScript #WebDevelopment

Optimize Re-renders with React.memo Avoid unnecessary re-renders in React functional components by using React.memo. It memoizes your component and only re-renders it when props change — great for performance! Typing in the input won’t trigger a re-render of the Child component because it’s wrapped with React.memo. Less re-render = smoother performance! #ReactJS #JavaScript #FrontendDevelopment #WebDevelopment #ReactTips #CodingTips
