Optimize Imports with ES Modules for Smaller Bundles

useEffect is one of the most misunderstood hooks in React. It’s not for: • calculating derived values • syncing state with state • fixing re-render issues It is for: • data fetching • subscriptions • timers • syncing with browser or external systems If something can be calculated from existing state or props, it doesn’t belong in useEffect. The less effects you write, the more predictable your React code becomes. #react #frontend #javascript #webdev #cleanCode

React Performance isn’t about adding hooks everywhere. It’s about adding them where they matter. Most applications suffer from unnecessary re-renders and unstable references. Two small hooks. Massive impact: 1. useCallback → Stabilize function references 2. useMemo → Avoid expensive recalculations But misuse them, and you just add complexity with zero gains #ReactJS #NextJS #FrontendDevelopment #WebPerformance #JavaScript #SoftwareEngineering #ReactPerformance #Optimization #CleanCode #TechLeadership #UIDevelopment #ProgrammingTips

frameworks and libraries is all about syntax, the real deal is knowing what powers them... useEffect and useState are dangerous syntax to someone who doesn't understand how window loaded and DomContent event listeners work in pure javaScript... Axios is great but if you dont know how the fetch API works, the you would struggle to undertstand how the browser handles http errors... Knowing the fundamentals isn't about going back to the stone age, its what you need to build with confidence. #reactjs #frontend #javaScript

Granular runs directly in the browser as native ES modules. No Babel. No Webpack. No 738-package dependency tree just to render a button. Want a better dev experience? Use Vite. But it's optional, not mandatory. The framework works without a build step at all. Compare that to React, where you need a transpiler for JSX, a bundler for modules, and a dev server for hot reloading - before you write a single line of application code. Granular is just JavaScript. Import it, use it, ship it. npm create @granularjs/app my-app GitHub: https://lnkd.in/dZGxj8Dy #javascript #frontend #webdev #opensource #developer

🚀 Understanding the useEffect Hook in React useEffect is a powerful hook used to handle side effects in functional components, such as: API calls Subscriptions & event listeners Timers Cleanup on unmount Key concepts covered ✔️ Mount → runs after initial render ✔️ Update → re-runs when dependencies change ✔️ Unmount → cleanup to prevent memory leaks ✔️ Dependency array → controls when the effect runs Strong understanding of hooks leads to cleaner, scalable, and more predictable React applications. #ReactJS #useEffect #FrontendDevelopment #JavaScript #WebDevelopment #ReactHooks #SoftwareEngineering #LearningJourney

🚨 Stop using useEffect for everything in React. If you're still using useEffect to: • Derive state from props • Transform data for rendering • Handle simple computations You're probably writing more bugs than you think. 💡 React tip: 1️⃣ Derived data belongs in useMemo, not useEffect 2️⃣ Event-driven logic belongs in handlers 3️⃣ Effects are for synchronization with external systems The less useEffect you write, the more predictable your component becomes. Clean React code is about eliminating unnecessary effects. What’s one place you removed useEffect and simplified your code? #ReactJS #FrontendDevelopment #JavaScript #SoftwareEngineering #CleanCode

🚀 Why React.js Hooks are a game-changer: • ✅ Simplify your code and reduce boilerplate • ✅ Manage state easily with useState • ✅ Handle side effects smoothly with useEffect • ✅ Share logic across components with custom hooks • ✅ Improve component composition and reusability • ✅ Make functional components more powerful 💡 Embrace hooks for cleaner, modern React development! #ReactJS #Hooks #WebDevelopment #FrontendDevelopment #JavaScript #CodingTips #TechLearning #DeveloperLife #CleanCode #FunctionalProgramming

JavaScript Closures: Your Code's Secret Memory Keeper! 🤫 Ever wonder how functions remember things even after they're done running? It's not magic, it's CLOSURES! ✨ Level up your JavaScript game with Closures! 🚀 This powerful concept lets functions "remember" their environment, creating private variables and stateful functions. Perfect for building things like counters, private data, and more! Get ready to impress your tech crush. 😉 #JavaScript #Closures #WebDev #CodingTips #FrontendDeveloper #TechInfluencer #JS ⚙️ Built using my automated code-to-image server and n8n.

🔥 React 19 just made useEffect optional for data fetching. For years we wrote: useEffect useState loading flags error state Now? const user = use(getUser()); React waits. Suspends. Renders when ready. No effect boilerplate. This isn’t a new hook. It’s a new mental model. Async is now part of render. Are you still fetching after render? #React19 #ReactJS #Frontend #JavaScript #WebDev

🚀 30 Days — 30 Coding Mistakes Beginners Make Day 10/30 I increased state twice… but it only updated once 😐 setCount(count + 1) setCount(count + 1) I expected +2 I got +1 Because React batches state updates. Both lines used the same OLD value of `count`. Fix 👇 setCount(prev => prev + 1) Functional updates always receive the latest state. This is very important in: counters, carts, likes, and real-time UI. Day 11 tomorrow 👀 #30DaysOfCode #reactjs #javascript #frontend #webdevelopment #codeinuse
