React.js Evolution: A Journey Through Time with Jordan Walke

🧑💻 𝗥𝗲𝗮𝗰𝘁 𝗡𝗮𝘁𝗶𝘃𝗲 𝘃𝘀 𝗙𝗹𝘂𝘁𝘁𝗲𝗿 — 𝗔𝗻 𝗛𝗼𝗻𝗲𝘀𝘁, 𝗣𝗿𝗮𝗰𝘁𝗶𝗰𝗮𝗹 𝗖𝗼𝗺𝗽𝗮𝗿𝗶𝘀𝗼𝗻 This is a question that comes up in almost every mobile team discussion. After working with React Native in real-world projects (and seeing Flutter in action across teams), here’s a practical take — not hype, just experience. ⚙️ 𝗣𝗲𝗿𝗳𝗼𝗿𝗺𝗮𝗻𝗰𝗲 Both frameworks are fast enough for most production apps. • Flutter feels slightly smoother out of the box because it controls its own UI rendering. • React Native performance is solid, especially with modern features like the new architecture, Hermes, and optimized native modules. 👉 In real apps, performance issues usually come from poor state management or heavy logic, not the framework. 🛠 𝗗𝗲𝘃𝗲𝗹𝗼𝗽𝗲𝗿 𝗘𝘅𝗽𝗲𝗿𝗶𝗲𝗻𝗰𝗲 This is where preferences really show. • React Native is a big win if JavaScript/TypeScript and React are already familiar. Code reuse between web and mobile is a real advantage. • Flutter offers a very consistent experience since everything is written in Dart and controlled by the framework itself. 👉 For React developers, React Native feels natural and productive from day one. 🎨 𝗨𝗜 & 𝗖𝘂𝘀𝘁𝗼𝗺𝗶𝘇𝗮𝘁𝗶𝗼𝗻 • Flutter gives pixel-perfect UI across platforms with its widget system. • React Native uses native components, so apps feel more “platform-native” by default. 👉 If deep custom UI is needed, both can do it — just in different ways. 🌍 𝗘𝗰𝗼𝘀𝘆𝘀𝘁𝗲𝗺 & 𝗖𝗼𝗺𝗺𝘂𝗻𝗶𝘁𝘆 • React Native benefits from the massive JavaScript ecosystem and long-term industry adoption. • Flutter has strong backing from Google and growing community support. 👉 Finding libraries, tools, and developers is still easier with React Native. 🧠 𝗙𝗶𝗻𝗮𝗹 𝗧𝗵𝗼𝘂𝗴𝗵𝘁 There’s no “best” framework — only the right tool for the team and product. Choose React Native if React/JS experience already exists and fast development matters. Choose Flutter if consistent UI and tight framework control are top priorities. Both are production-ready. The real difference comes down to team skills, long-term maintenance, and project goals. #ReactNative #Flutter #Dart #Javascript #ReactJS  #CrossPlatform #MobileDev

🚀 What is React.js? 🚀 Ever wondered what powers the dynamic and snappy user interfaces of websites like Facebook, Instagram, and Netflix? Chances are, it's React! React.js is a declarative, efficient, and flexible JavaScript library for building user interfaces. Developed by Meta (formerly Facebook), it allows developers to create large web applications that can change data without reloading the page. Its core strengths lie in: 🔹 Component-Based Architecture: Build encapsulated components that manage their own state, then compose them to make complex UIs. 🔹 Virtual DOM: React creates an in-memory data structure cache, computes the resulting differences, and then updates the browser's displayed DOM efficiently. 🔹 Declarative Views: Make your code more predictable and easier to debug. Whether you're a seasoned developer or just starting your coding journey, React is a powerful tool to have in your arsenal. What do you love most about React?

🚀 React Native Gets the New API — Smarter UI + Better Performance React 19.2 just introduced a powerful new feature in React Native: the <Activity> component, and it’s a game changer for UI visibility, performance, and navigation flow. 🔴 What is <Activity>? lets you split your UI into separate “activities” that React can: Show Hide Pause Resume ...without losing state. It supports two modes: 🔵 visible UI is shown Effects are mounted Updates run normally 🔵 hidden UI disappears Effects unmount Work is paused/deferred State is preserved Yes — if you hide a tab/screen with <Activity mode="hidden"> and return later, your search results, scroll position, filters, and selections all stay intact. 💡 Why is Better Than Conditional Rendering When you hide something using {condition && <Component /> }, React fully unmounts it. With <Activity>, React can pause the UI without destroying its state. This leads to: Faster tab switching. Smoother onboarding flows. Better performance under heavy screens. No unnecessary re-renders ✨ Real Difference React Native even demonstrated how 19.1.1 struggled with background UI — and how 19.2 (with ) fixes it through smarter scheduling. #ReactNative #ReactJS #React19 #ActivityAPI #MobileDevelopment #JavaScript #CrossPlatform #Frontend #UIUX #AppPerformance #TechUpdate #DevCommunity #ReactNativeDevelopers #Programming #SoftwareEngineering

🚀 React.js Overview React.js is a popular JavaScript library used to build fast, interactive, and scalable user interfaces, especially for single-page applications. Developed and maintained by Meta (Facebook), React focuses on creating reusable UI components that make applications easier to develop and maintain. ✨ Why React.js? Component-based architecture for reusable code Virtual DOM for high performance and efficient updates Strong community support and vast ecosystem Widely used by companies like Facebook, Instagram, and Netflix 🔑 Key Concepts Components – Building blocks of the UI JSX – HTML-like syntax inside JavaScript Props & State – Manage and pass data dynamically Hooks – Add state and lifecycle features to functional components video in YouTube link -https://lnkd.in/gbZDxN6W 🌐 Use Cases Web applications Dashboards E-commerce platforms Mobile apps (via React Native) React.js continues to be a top choice for modern front-end development due to its performance, flexibility, and developer-friendly approach. #ReactJS #WebDevelopment #JavaScript #Frontend #Programming #Tech

1/2026 #Performance #reactjs I opened react.dev (React Blog) in Chrome DevTools → Performance, not expecting much… but the numbers made me pause. 📊 What I saw (Core Web Vitals): • LCP: 0.28s • CLS: 0 • INP: 64ms Everything loads instantly. Nothing jumps. Every interaction feels… calm. And honestly, that’s rare. What stood out to me wasn’t just the metrics — it was the feeling. The page feels stable. Predictable. Respectful of the user’s time. That doesn’t happen by accident. It’s the result of: • Server-first rendering • Minimal JavaScript • Stable layouts • Intentional design decisions No flashy tricks. Just solid fundamentals done really well. As frontend developers, we often chase features, libraries, and frameworks. But experiences like this remind me: 👉 Performance is a feature. 👉 Less JavaScript is often better JavaScript. 👉 A fast app feels trustworthy. Google now treats Core Web Vitals as UX signals, but even without Google, users can feel when an app is slow or unstable. This was a good reminder for me: • Measure real interactions, not just Lighthouse scores • Pay attention to INP, not only load time • Build layouts that never surprise users • Treat the main thread like a limited resource React.dev quietly sets a high bar for all of us. Curious to hear from other devs here: How often do you actually open DevTools → Performance on your own projects? #ReactJS #FrontendEngineering #WebPerformance #CoreWebVitals #INP #UX #JavaScript #DeveloperLife #Learning

Why Next.js is more powerful than React (and when it matters) React is an excellent library for building user interfaces. But when it comes to building production-ready applications, Next.js takes things to another level. Here’s why 👇 1️⃣ Rendering flexibility React apps are typically client-side rendered. Next.js supports: >Server-Side Rendering (SSR) >Static Site Generation (SSG) >Incremental Static Regeneration (ISR) This means better performance, better SEO, and faster load times. 2️⃣ Built-in routing and structure With React, routing and architecture decisions are manual. Next.js provides a file-based routing system that simplifies scalability and keeps projects organized. 3️⃣ Backend capabilities Next.js isn’t just frontend. It allows you to create API routes within the same project, enabling full-stack development without a separate backend for many use cases. 4️⃣ Performance optimizations out of the box Next.js automatically handles: >Code splitting >Image optimization >Font optimization These optimizations require extra effort in a traditional React setup. 5️⃣ Production readiness Next.js is designed for real-world applications: >SEO-friendly by default >Better deployment workflows >Scales well for enterprise-level apps React gives you flexibility. Next.js gives you structure, performance, and scalability. That’s why many modern web applications start with React — but move to Next.js for production. 💬 Do you prefer React or Next.js for large-scale applications? Why? #NextJS #ReactJS #FullStackDeveloper #WebDevelopment #JavaScript #Frontend #SoftwareEngineering

🎯My experience over the past few months, 🎭Same Language, Different Reality A lot of people assume that if you know React, you automatically know React Native or Next.js. I used to think that too, until I started working deeply with both. Yes, they share the same language (JSX / TSX) and a similar component syntax. But beyond that, they are solving very different problems, in very different environments. 🔄 Data Fetching feels similar, but behaves differently On the web (React / Next.js), data fetching is tied to: server vs client execution rendering strategies (SSR, SSG, streaming) caching and revalidation In React Native, fetching is always client-side: lifecycle based dependent on network conditions often combined with offline handling The same API call requires a completely different mindset. 📖 Rendering & Reading Data Web apps think in terms of: HTML hydration browser behavior SEO React Native doesn’t deal with any of that. There’s no DOM, no browser, just native UI threads communicating through a bridge. Understanding this changes how you structure components and state. 🎨 UI & UX are not interchangeable Web UI focuses on: responsiveness screen sizes mouse & keyboard interactions Mobile UI is: touch first gesture driven platform sensitive (Android vs iOS) Writing JSX might look the same, but designing good UX is completely different. 🔌 API & Application Flow In Next.js, APIs are often part of the same project: middleware server actions cookies and headers In React Native, everything is external: authentication storage permissions background tasks native limitations The architecture forces you to think more carefully about boundaries. 💡 What I learned by exploring both The biggest realization for me was this: They are not substitutes, they are complements. Learning both: improves how you design APIs makes you more intentional about UX helps you avoid assumptions and teaches you to respect the platform you’re building for Same language. Different constraints. And understanding those constraints is what actually makes you a better engineer. #ReactJS #NextJS #ReactNative #SoftwareArchitecture #Engineering #WebDevelopment #MobileDevelopment #UXThinking #LearningInPublic

React Native in 2025: Is the "Bridge" Finally Dead? If you are still thinking of React Native as "just a wrapper," you’re missing out on the biggest architectural shift in mobile dev history. For years, we relied on the "Bridge"- the layer that serialized data into JSON to pass it between JavaScript and Native. It worked, but it was a bottleneck for high-performance apps. Here is why 2025 is the year of High-Performance React Native: Goodbye Bridge, Hello JSI: The New Architecture uses the JavaScript Interface (JSI), allowing JavaScript to call Native functions directly. No more JSON serialization delay. TurboModules: Native modules now load lazily, meaning your app's startup time just got a massive boost. Fabric Rendering: A new, high-priority rendering system that makes complex animations feel as smooth as a native Swift or Kotlin app. The Performance "Cheat Sheet" for your next build: FlashList vs FlatList: Switch to Shopify’s FlashList for 10x better performance in long lists. Zustand vs Redux: Move to Zustand for minimal boilerplate and faster state updates. Hermes Engine: Ensure Hermes is enabled to reduce your app's memory footprint and TTI (Time to Interactive). The Bottom Line: React Native isn't just for MVPs anymore. With the New Architecture, it’s a powerhouse for high-scale production apps. Are you still building with the Bridge, or have you migrated to the New Architecture? Let’s talk in the comments!
