React Learning Journey: Understanding the onChange Property Today, I deepened my understanding of how the onChange property works in React. Unlike vanilla JavaScript where we listen for events directly on the DOM, React uses onChange as a way to track user input and update state seamlessly. It’s a simple concept, but once you truly get it, it changes how you think about managing dynamic data in forms. Here’s what I practiced 👇 - Updating component state in real time as the user types - Making inputs fully controlled through React state - Building a small interactive example to visualize the concept I’ve attached a small snippet from my code. Every little concept adds up. Step by step, I’m building a strong foundation in React and front-end development. #React #FrontendDevelopment #WebDevelopment #LearningInPublic #ReactJS #JavaScript

✨ "The best way to learn React is to build with it!" ✨ Excited to share my latest project — Background Color Changer 🎨⚛️ This project allows users to dynamically change the background color of the page with a single click — built entirely using React.js. It’s a simple yet effective way to explore React’s state management and event handling concepts in action. 💡 Through this project, I practiced: ✅ Using React useState hook for managing component state ✅ Implementing event-driven interactivity ✅ Strengthening my understanding of React fundamentals and component-based architecture A big thank you to Sonia Ma’am and Shanthi Ma’am for their continued guidance and motivation. 🙏 🎯 Check out the project here: https://lnkd.in/ejEmHxa6 💻 GitHub Repository: https://lnkd.in/ebwi6W5n #ReactJS #WebDevelopment #CodingJourney #JavaScript #LuminarTechnolab #LearningByDoing #FrontendDevelopment

Tutorial Hell Weekend 😅🔥 As I mentioned last week, I had full free access to Vue School tutorials over the weekend. Of course, I didn’t just hit “Play All” and code until my eyes gave up 😄 — instead, I picked a few courses that felt most interesting and useful at the moment: 💡 What I focused on: TypeScript in Vue (I’ve worked with TS before — especially while learning Angular — but never inside Vue) Tailwind CSS Nuxt.js → this one was the most important for me since I had zero experience with it before. I know tutorials can be super helpful — especially when the tutor explains the logic clearly and shows how to use the documentation properly. But at the same time, they can also slow down our growth if we rely on them too much. Personally, I believe nothing is purely good or bad — it all depends on how we use it and whether we can turn it into an advantage. Here’s my little learning tactic 👇 1️⃣ Watch the tutorial — but instead of just copying code, focus on understanding the logic behind it. 2️⃣ Try to recreate the same example without watching the video, using only the official docs. 3️⃣ Build one or more small projects that include what you’ve learned. 4️⃣ Finally, apply everything inside a bigger, more complex project. 💬 What do you think about this approach? Do you have any personal learning tips that help you balance tutorials and real practice? #vuejs #nuxt #typescript #tailwindcss #webdevelopment #learningbydoing #frontenddeveloper #javascript #programmingjourney #developers

As I’ve been diving deeper into React.js, I thought it would be helpful to put everything I’ve learned in one place from JSX, components, props, and state, to hooks and event handling all with simple code examples anyone can follow. 💡 What’s inside my React Beginner’s Guide: ✅ Step-by-step setup with Create React App ✅ Understanding JSX and how rendering works ✅ Functional vs Class Components ✅ Working with Props & State ✅ Handling Events & Conditional Rendering ✅ Intro to React Hooks (useState, useEffect, and more) I’m still learning React every day, and honestly, there’s so much more to explore (routing, APIs, advanced hooks… the list goes on 👀). Let’s keep building, experimenting, and growing together 💻🔥 #React #WebDevelopment #Frontend #CodingJourney #JavaScript #Programming #LearnInPublic #ReactJS #Developers #CodeNewbie

⚛️ React.js Day 5 — Props & React Fragments Day 5 of my React.js learning journey! Today, I explored two important topics — Props and React Fragments What are Props? Props (short for properties) are used to pass data from one component to another — usually from parent to child. Props are read-only, meaning they cannot be modified by the child component. They help make components reusable and dynamic. Example: function Welcome(props) { return <h2>Hello, {props.name}!</h2>; } function App() { return <Welcome name="Prachi" />; } Here, name is a prop passed from App to Welcome. What are React Fragments? React Fragments let you group multiple elements without adding extra nodes to the DOM. Useful when you want to return multiple elements from a component without wrapping them in a <div>. Example: function Info() { return ( <> <h3>React Fragments</h3> <p>They help avoid unnecessary HTML wrappers.</p> </> ); } <>...</> is a shorthand for <React.Fragment>. #ReactJS #ReactProps #ReactFragments #ReactLearning #ReactSeries #LearnReact #FrontendDevelopment #WebDevelopment #JavaScript #ReactDeveloper #CodeNewbie #100DaysOfCode #DeveloperJourney

Exploring React Component Lifecycle! In this short demo, I built a React class component that tracks elapsed time every second ⏱️ — and intelligently logs a message every 5 seconds based on state updates. This hands-on project helped me gain deeper clarity on how React lifecycle methods work in real scenarios: 1.componentDidMount() — initializes the timer when the component loads 2. componentDidUpdate() — observes state changes and triggers milestone logs 3. componentWillUnmount() — performs clean-up to prevent memory leaks It’s a small experiment, but a meaningful step in strengthening my understanding of React’s lifecycle flow. Check out the video to see these lifecycle stages in action!

🚀 Still learning React the hard way ? Here’s the shortcut I wish I had earlier. I’ve compiled my handwritten notes on ReactJS into a simple and clear format that breaks down the core concepts without overwhelming beginners. From components and props to hooks, state management and lifecycle, these notes focus on helping you understand why things work the way they do, not just how. If you’re starting your React journey or revising the fundamentals, these notes will help you grasp concepts faster and build with more confidence. 📢 If you found this helpful, drop a comment and I’ll keep posting more handwritten notes. #ReactJS #FrontendDevelopment #WebDevelopment #JavaScript #LearnReact

🚀 React Learning Update – Event Handling in React! Today I practiced how different React events work and how to trigger functions inside a component. I wrote a small component where I used multiple event handlers to understand how React responds to user interactions. Here’s what I learned from this code: 🔹 Calling functions on button click (onClick) 🔹 Triggering actions when mouse enters a button (onMouseEnter) 🔹 Detecting scroll activity using (onWheel) 🔹 Tracking user input with (onChange) 🔹 Handling continuous mouse movement (onMouseMove) 🔹 Creating inline functions directly inside JSX 🔹 Understanding event objects like elem.target.value This hands-on practice helped me understand how React handles events just like JavaScript but in a more organized, component-based way.

Let's talk about React fundamentals. I often see developers get tangled in the 'why' of React. Why the V-DOM? What’s the real difference between props and state? Why is it 'declarative'? To help clear the confusion, I’ve created a 14-page, no-fluff guide that breaks down the core concepts of Modern React. This is the roadmap I use to explain the fundamentals to my team or when mentoring. No one should have to "fear to ask." Inside the PDF, I've broken down: ✅ The "Smart LEGO" analogy to finally make components click. ✅ The "Blueprint" model (Declarative vs. Imperative). ✅ A map of the modern ecosystem (Next.js, Vite, etc.). ✅ My complete VS Code toolkit & dev environment setup. My goal is to give back and help make these powerful concepts accessible to everyone, whether you're a beginner or just need a refresher. 📖 Swipe through the full PDF and let me know: What's one React concept you wish someone had explained to you more simply when you first started? #react #reactjs #javascript #frontenddevelopment #webdevelopment #softwareengineering #programming #techtips #uidevelopment #nextjs #wordpressdeveloper
