Understanding React Native Component Lifecycle for Better Apps

React Developers, Have You Noticed This Big Shift? If you’ve recently created a new React project using Vite, Next.js, or any modern setup, you probably noticed something different: 👉 React projects now use .jsx by default instead of .js for components. But here’s the interesting part… React did NOT remove .js support. The ecosystem simply evolved — and there are strong reasons behind this change. Modern React relies heavily on JSX, and JSX is not plain JavaScript. By using .jsx, tools and editors can instantly recognize and optimize your component files. That means better: Syntax highlighting Autocomplete Error detection Code refactoring Developer experience Build tools like Vite and Next.js now default to files like: App.jsx main.jsx This improves project clarity, helping developers quickly differentiate between component files and pure logic files. Can you still use .js for components? Absolutely. It still works perfectly. But you may lose JSX-specific improvements in your editor, which can affect your development speed and debugging. Best practice for 2025/2026: Use .jsx for all React components. Use .js for utilities, helpers, configs, and non-JSX logic. Why does this matter? Because this shift is part of a bigger movement toward cleaner architecture, more maintainable codebases, improved tooling, and a smoother developer experience overall. 💬 I’m curious — which one do you use for your components? .js or .jsx? And why? Share your thoughts in the comments.

⚛️ React — The Beginning of My Deep Dive Continuing my journey of strengthening my foundations as a full-stack developer, I started revisiting React, focusing on not just how things work, but why they work that way. Today, I explored some of the core fundamentals that form the backbone of every React application: 📘 Introduction & It's Need — understanding the problems React solves and how it simplifies UI development. 🧩 Components — the building blocks of reusable and maintainable interfaces. 🧠 JSX — how JavaScript and HTML blend to create powerful, declarative UI logic. 🎯 Props — making components dynamic and flexible through data flow. 🔁 Conditional Rendering — rendering UI based on state and logic. 📋 Rendering Lists — efficiently displaying collections and understanding the role of keys. It’s refreshing to revisit these concepts with a more mature perspective — focusing not just on syntax, but on conceptual clarity and reasoning behind each part. Small steps like these make a huge difference in becoming a better engineer — one concept at a time 🚀 #React #FrontendDevelopment #MERN #WebDevelopment #LearningJourney #SoftwareEngineering #ReactJS

⚡️React Native 0.82.1 — Better or Still a Bug Trap? 🤔 Last week, I tried to start a new React Native project… and it turned into an unexpected debugging journey. In my previous project (GoStock), I worked with React Native 0.82.0 and quickly ran into major issues — from SQLite not working properly to chart libraries breaking and other hidden module conflicts. To get the project running smoothly, I rolled back to 0.81.0, which was way more stable. Everything worked fine, and I wrapped up successfully. Now fast-forward to today — I tried creating a new project again using 0.81.0, but React Native had other plans. Installation failed because the newer 0.82.1 version introduced a new template.config.js that blocks the old template setup. So I did a bit of digging… and found that 0.82.1 was released mainly to fix the exact bugs that made 0.82.0 unstable. 💡 My takeaway: Every minor version isn’t just “a small update.” Sometimes, it’s a massive under-the-hood change that can make or break your workflow. Always read the release notes before upgrading or downgrading. Now I’m curious 👇 👉 Have you tried React Native 0.82.1 yet? Did it actually fix the SQLite and charts issues for you, or are the bugs still hanging around?

React 19 is redefining modern frontend development, here’s everything we need to know 👇 As a Full-Stack Developer, I’ve always loved how React keeps evolving — and this new release, React 19, takes things to the next level. It’s not just a version update — it’s a complete upgrade in how we handle async logic, forms, and server-side rendering. Here’s how React 19 compares to React 18 👇 🧩 React 18 Highlights ✅ Introduced Concurrent Rendering ✅ Added Suspense for async data fetching ✅ Introduced useTransition, useDeferredValue, and useId ✅ Automatic Batching of state updates ✅ Improved Streaming SSR 🚀 React 19 — What’s New 🌐 Actions → Simplifies async workflows & form handling 🔧 New Hooks → useActionState, useFormStatus, useOptimistic 🧠 Server Components & Actions → Fully stable for production 📘 use() API → Fetch async data directly in components ⚙️ Better SSR & Hydration → Faster and smoother rendering 📌 Ref as a prop → No need for forwardRef anymore 💎 Support for Custom Elements 🪄 New <Activity /> Component and useEffectEvent Hook (React 19.2 update) From a developer’s perspective, this release makes React more powerful, scalable, and easier to manage for large projects. It bridges the gap between frontend interactivity and backend data, giving developers cleaner, more intuitive tools to work with. As someone passionate about building full-stack web solutions, updates like these remind me why I love working in the React ecosystem. It’s constantly evolving — and so am I. 💭 What’s your favorite new feature from React 19? Have you tried it yet or planning to upgrade soon?

UseCallback and useMemo - It’s Not About Optimization, It’s About Control 🎯 💡 React Native ( or React ) developers often use useCallback and useMemo for the wrong reason. We say: “I use them for performance optimization.” But here’s the truth 👇 They’re not just about performance — they’re about stability and control. ⚙️ 1️⃣ useCallback — Control your function identity Without it, every render creates a new function reference — which triggers unnecessary re-renders in memoized child components. const handlePress = useCallback(() => { doSomething(); }, [dependency]); ✅ Keeps your function stable across renders. ✅ Works beautifully with React.memo() and expensive child components. ⚙️ 2️⃣ useMemo — Control your computed values It’s not just “cache results” — it’s “stabilize derived data.” const filteredList = useMemo( () => data.filter(item => item.active), [data] ); ✅ Prevents recalculating large lists or derived values on every render. ✅ Reduces JS thread churn in React Native. #ReactNative #ReactJS #JavaScript #Performance #Frontend #MobileDevelopment #CodingTips

Why I Always Create a Custom Hook Instead of Copying and Pasting Logic When I started working with React and React Native, I used to duplicate logic across multiple components. Fetching data, handling loading states, managing forms, you name it. But over time, I realized one thing: Repeated logic = repeated bugs. Now, whenever I see a pattern repeating twice, I turn it into a custom hook. It keeps my code clean, reusable, and easy to debug.
