This project is "Eat-n-Split," a React-based web app for splitting bills among friends. Built with React 19, it features a clean UI where users can add friends, select them to split expenses, and track balances (who owes whom). Key components include a friends list, add-friend form, and bill-splitting calculator. It demonstrates React fundamentals like state management with useState, component composition, and event handling. Perfect for group outings or shared expenses! 🚀 Project: https://lnkd.in/e477xkJN #React #JavaScript #Webdevelopment

🚀 Boost Your React App Performance with Lazy Loading! If your React app feels slow or heavy on initial load, it’s time to implement lazy loading — one of the simplest yet most powerful performance optimization techniques. 🔍 What is Lazy Loading? Lazy loading allows you to load components only when they are needed, instead of loading everything upfront. This reduces bundle size and improves initial load time. 💡 Why it matters? ✔ Faster page load ✔ Better user experience ✔ Improved performance score (Lighthouse 🚀) ✔ Optimized resource usage ⚙️ How to implement in React: import React, { Suspense, lazy } from "react"; const Dashboard = lazy(() => import("./Dashboard")); function App() { return ( <Suspense fallback={<div>Loading...</div>}> <Dashboard /> </Suspense> ); } export default App; 🔥 Pro Tips: Use lazy loading for routes and heavy components Combine with React Router for route-based splitting Always wrap with Suspense for fallback UI Avoid overusing — balance is key! 📈 Small optimization → Big impact in scalability. #ReactJS #WebPerformance #FrontendDevelopment #MERNStack #JavaScript #CodeOptimization #SoftwareEngineering

Typing in your React app… and it feels slow? 😵💫 Characters lag, UI stutters, and the experience just feels off. You’re not alone — this is a super common issue, especially in large forms or dashboards. 💡 The problem usually isn’t React itself… it’s how we handle state and re-renders. 𝗛𝗲𝗿𝗲’𝘀 𝘄𝗵𝗮𝘁’𝘀 𝗼𝗳𝘁𝗲𝗻 𝗰𝗮𝘂𝘀𝗶𝗻𝗴 𝘁𝗵𝗲 𝗹𝗮𝗴: 👉 Every keystroke triggers a re-render of the entire component 👉 Heavy computations running on each input change 👉 Unoptimized state updates 👉 Unnecessary API calls on every character 👉 Large component trees re-rendering repeatedly 🚀 𝗛𝗼𝘄 𝘁𝗼 𝗳𝗶𝘅 𝗶𝘁: ✔️ Use useCallback to prevent unnecessary function recreation ✔️ Memoize expensive calculations with useMemo ✔️ Split components to isolate re-renders ✔️ Debounce API calls instead of firing on every keystroke ✔️ Consider controlled vs uncontrolled inputs wisely ⚡ 𝗦𝗺𝗮𝗹𝗹 𝗼𝗽𝘁𝗶𝗺𝗶𝘇𝗮𝘁𝗶𝗼𝗻𝘀 = 𝗠𝗮𝘀𝘀𝗶𝘃𝗲 𝗽𝗲𝗿𝗳𝗼𝗿𝗺𝗮𝗻𝗰𝗲 𝗯𝗼𝗼𝘀𝘁 A smooth input field might seem small… but it directly impacts user experience, retention, and perception of your app. 💬 Have you ever faced input lag in React?

Is your React app feeling sluggish? Performance optimization isn't about minor tweaks—it's about systematically identifying and eliminating bottlenecks that impact user experience. When bundle sizes grow, conversion rates can drop. Fortunately, many React performance issues follow predictable patterns. Start with the React DevTools Profiler to measure rendering costs. By recording your app's interactions, you'll pinpoint components with long render times and frequent re-renders. This data-driven approach is essential. Next, tackle unnecessary re-renders with tools like React.memo and useMemo. These strategies ensure that components only re-render when necessary, improving responsiveness. Bundle size is another critical factor. Implement route-based and component-based code splitting to enhance load times, especially on mobile networks. Finally, remember that performance optimization is an ongoing process. Set up monitoring to catch regressions and continuously refine your app. Curious to dive deeper?

If you're building an Angular app, one common problem is this: As your app grows, it becomes slower to load ⏳ Why? Because everything is loaded at once when the app starts. 💡 This is where Lazy Loading helps. 👉 Instead of loading the whole app at once, Angular loads parts of your app only when they are needed. 📌 Simple Example: When a user clicks on the "Admin" page, only then that part of the app will load. { path: 'admin', loadComponent: () => import('./admin/admin.component') .then(m => m.AdminComponent) } What you get: - Faster app start - Better performance - Smooth user experience In simple words: "Load only what you need, when you need it." #Angular #Frontend #WebDevelopment #JavaScript #Coding

Day [12] Code for Change Most Next.js apps make users wait longer than necessary. The solution is using Suspense along with loading.tsx. <Suspense> (from React) lets you wrap slower components so they can load independently instead of blocking the entire page. loading.tsx (in Next.js) is a file-based way to show a fallback UI automatically while a route is loading. This means: • Fast parts of the UI render immediately • Slow parts load in the background • Users see a loading state instead of a blank screen Difference: Suspense controls how individual components load. loading.tsx handles loading at the route level automatically. Used together, they make your app feel faster without adding complex logic. #NextJS #React #WebDevelopment
