For a few days, I was working on building a sticky Notes App using Node.js and Express.js, and instead of using plain HTML, I experimented with EJS (Embedded JavaScript templates). While doing that, I noticed some interesting differences between using static HTML and server-side templating with EJS: • With HTML, everything is static and separate • With EJS, I can dynamically render data directly from the backend • Passing variables from Express to views makes the app feel more “real-time” and flexible • Folder structure becomes more organized when separating routes, views, and logic • It feels closer to how real-world backend-driven applications work This project enhanced my understanding of how frontend and backend integrate more seamlessly through the use of templating engines. I would love to hear how others approach structuring Node.js + Express projects with EJS, and if there are any improvements or best practices you would recommend to make this setup more efficient or scalable. #Nodejs #Expressjs #EJS #BackendDevelopment #WebDevelopment #LearningByDoing

React and React Native look similar on the surface. But building a real project in both teaches you things no tutorial will. A few honest takeaways: ❌ Assuming web knowledge directly transfers ✅ It mostly does — but mobile adds a whole new layer: gestures, safe areas, platform-specific behaviour ❌ Styling the same way you do on web ✅ Embrace StyleSheet and flexbox in React Native. Fighting it will cost you hours. ❌ Ignoring performance early ✅ FlatList over ScrollView for long lists. Memoize where it matters. Mobile is less forgiving than a browser. ❌ Treating navigation as an afterthought ✅ Plan your navigation structure before you write a single screen. One codebase, two platforms, a lot of lessons. Still building — but already learning more than I expected. Save this if you're thinking of making the jump to React Native 🔖 #ReactNative #ReactJS #JavaScript #MobileDev #Frontend #LearnInPublic

Mastering React JS starts with strong fundamentals 🚀 Before jumping into advanced concepts, every developer should clearly understand these core basics: 🔹 Components (Functional & Class) The building blocks of any React application. Everything in React is a component. 🔹 JSX (JavaScript XML) Allows you to write HTML-like code inside JavaScript, making UI development more intuitive. 🔹 Props (Passing Data) Used to pass data from one component to another — enabling reusability and clean architecture. 🔹 State (Managing Data) Handles dynamic data inside components and controls how the UI updates. 💡 Key Insight: A strong understanding of these fundamentals makes learning advanced topics like Hooks, State Management, and Performance Optimization much easier. 📌 Don’t rush into advanced React — build a solid foundation first.

🚀 Exploring React JS Hooks – A Game Changer! As a developer working with React, I’ve recently been diving deeper into React JS Hooks, and honestly, they’ve completely changed the way I write components. 🔹 Hooks allow us to use state and lifecycle features in functional components 🔹 They make code more readable and reusable 🔹 No need to rely heavily on class components anymore Some commonly used hooks: ✅ useState – for managing state ✅ useEffect – for handling side effects ✅ useContext – for global state management ✅ useRef – for accessing DOM elements ✅ useMemo & useCallback – for performance optimization 💡 Why Hooks matter? They simplify complex logic, reduce boilerplate code, and make your React applications more scalable and maintainable. If you're working with React and not using hooks yet, you're definitely missing out! #ReactJS #WebDevelopment #FrontendDevelopment #JavaScript #Coding #SoftwareDevelopment

Why React.js Makes You a Better JavaScript Developer Want to really understand JavaScript? Dive into React.js. It’s more than a UI library — it’s a training ground for mastering JS fundamentals. Here’s why 👇 🪝 React forces you to think in JavaScript. You’ll constantly use functions, objects, arrays, and ES6+ features like arrow functions and destructuring. No shortcuts — just pure JS in action. #ReactJS #JavaScript #WebDev 🪝 You’ll master state & data flow. Props, state, and context aren’t magic. They’re JavaScript patterns applied at scale. React makes you wrestle with how data moves through an app. 🪝 Fundamentals become second nature. Closures, scope, immutability, event handling… React makes you practice these daily. They stop being abstract concepts and start being muscle memory. 🪝 Modern JS features everywhere. Hooks, async/await, modular imports React workflows naturally push you into the latest language features while building real projects 🪝 Confidence boost. Once you can manage complex UI with React, vanilla JS feels effortless. It’s like training with weights — everything else becomes lighter. React isn’t just about building interfaces. It’s a hands-on way to level up your JavaScript skills while creating something tangible. If you want to truly understand JS, React is the playground that makes the theory click. #Coding #Frontend #ReactJS

I used to think React.ReactNode and React.ReactElement were the same thing… They are NOT. And this mistake silently breaks a lot of beginner code Here’s the simplest way I now understand it: *React.ReactNode = anything React can render *React.ReactElement = only JSX elements Sounds small, but watch this If you write: children: React.ReactElement You just blocked this: <Container>Hello</Container> Because "Hello" is NOT a ReactElement. But when you use: children: React.ReactNode Now everything works: ✅ Text ✅ Components ✅ Elements ✅ Even null When to use : ✅ Use React.ReactNode when: * You’re typing children * You want flexibility * You don’t care what gets rendered, as long as React can display it Avoid React.ReactNode when: * You need strict control over what is passed ✅ Use React.ReactElement when: * You want ONLY JSX/components * You’re enforcing structure (e.g. design systems, wrappers) *Avoid React.ReactElement when: * You expect text, numbers, or mixed content What I learned today: TypeScript isn’t just about types… It’s about preventing subtle bugs before they happen I’m currently learning React + TypeScript and sharing what I discover daily.

If you’ve worked with React Native, you’ve probably faced moments where things just felt… slow—especially with animations or heavy interactions. A big reason for that was the old bridge. The bridge handled communication between JavaScript and native code, but it wasn’t very efficient. Everything had to be sent back and forth asynchronously, and data was converted into JSON each time. That added unnecessary delay and often became a bottleneck. JSI was introduced to fix exactly this. Instead of going through the bridge, JSI lets JavaScript talk to native code directly. No serialization, no waiting for async responses unless needed. This makes things much faster and smoother. In simple terms, JSI solved the core performance issue in React Native and made it possible for apps to feel much closer to truly native. #reactNative #frontendDevelopment #React #deepLearning
