🚀 Learning and Building with React ⚛️ Hello everyone 👋 Today, I learned some important React concepts and understood clearly what each one is and what it is used for: 🔹 Functional Components – What? -> Functional Components are JavaScript functions that return JSX (UI). -> What for? They are used to create reusable UI parts in a simple and clean way. 🔹 Props – What? -> Props (short for properties) are inputs passed from a parent component to a child component. -> What for? They are used to pass data and make components dynamic and reusable. 🔹 useState – What? -> useState is a React Hook that allows functional components to store and manage state. -> What for? It is used to update and track data like counters, timers, inputs, etc., and re-render the UI when the state changes. 🔹 useEffect – What? -> useEffect is a React Hook used to handle side effects in components. -> What for? It is used for tasks like API calls, timers, subscriptions, and running code when a component mounts, updates, or unmounts. 💡 Hands-on Practice: To apply these concepts, I built: ⏰ Digital Clock – updates time every second using useEffect ⏱ Stopwatch – manages seconds, minutes, and hours using useState and interval logic 📂 Source Code:https://lnkd.in/gq6S_FZD Learning step by step and building real projects to strengthen my foundation 🚀 #ReactJS #LearningAndBuilding #FunctionalComponents #Props #useState #useEffect #FrontendDevelopment #ReactJourney

Revisiting React Fundamentals 🚀 Over the past few days, I went back to the core concepts of React to strengthen my foundation. Instead of rushing into advanced libraries, I focused on understanding how React actually works under the hood. Here’s what I’ve revised and practiced so far: 🔹 JSX & component structure Understanding how UI is broken into reusable components and how JSX makes UI logic more readable. 🔹 Props vs State How data flows in React, passing props between components, and managing dynamic UI with useState. 🔹 Event handling Handling user interactions like clicks, inputs, and form submissions in a clean React way. 🔹 Conditional rendering Rendering UI based on conditions (ternary, &&, etc.) to make components dynamic. 🔹 useEffect basics Handling side effects like API calls, timers, and lifecycle behavior with useEffect. 🔹 Basic project structure Organizing folders, separating components, and writing cleaner, scalable code. Why this revisit? I realized strong fundamentals make advanced topics like performance optimization, state management, and full-stack development much easier to grasp. Currently continuing with: ➡️ Building small projects ➡️ Practicing problem solving ➡️ Strengthening JavaScript + React together Always open to feedback and learning from the community. What React concept do you think every developer should master early? #React #FrontendDevelopment #WebDevelopment #JavaScript #LearningInPublic #100DaysOfCode #DeveloperJourney #ReactJs

Still Learning. Still Building. Still Showing Up. Today I went deeper into Next.js — and honestly, it reminded me of something important: 👉Progress doesn’t come from motivation. 👉 It comes from consistency. ✅ What I explored in Next.js: ✨ App Router & file-based routing ✨ Server vs Client Components ✨ Layouts & loading states ✨ API routes ✨ Why Next.js is more than just React Big realization: Next.js teaches you how frontend meets backend — cleanly and professionally. Then I jumped into backend with NestJS 🛡️ ✅ What I learned in NestJS: ✨ Modules, Controllers & Services ✨ Building REST APIs ✨ Dependency Injection ✨ DTOs & validation ✨ Structured backend design Big realization: NestJS doesn’t just help you write APIs — it teaches you how to think like a backend engineer. 💭 My mindset today: Some days are hard. Some concepts don’t click immediately. Some bugs take hours. But I remind myself: 🔥 Every line of code matters 🔥 Every small step counts 🔥 Every day of learning compounds Frontend + Backend. Confusion + Curiosity. Practice + Patience. That’s how developers are made. let’s grow together🤝 #NextJS #NestJS #FullStackDeveloper #LearningInPublic #100DaysOfCode #WebDevelopment #ReactJS #NodeJS #JavaScript #DeveloperJourney #Consistency

🚀 30 Days of React.js Tips – Day 28 📌 Topic: Code Splitting & Lazy Loading Today’s learning was focused on improving application performance using Code Splitting and Lazy Loading — powerful techniques that help React apps load faster and run more efficiently. 📚 Key Learnings from Day 28: ✔ Breaking large bundles into smaller chunks with Code Splitting ✔ Loading components only when needed using React.lazy ✔ Using Suspense to create smooth loading experiences ✔ Displaying fallback UI like loaders or spinners ✔ Optimizing bundle size for better performance 💡 Why Code Splitting Matters: No user likes a slow application. By loading only the necessary code, we can significantly improve initial load time, enhance user experience, and build production-ready applications. 🔑 Key Insight: 👉 Load smarter, not heavier — ship only what users need. 📈 Becoming a better developer by focusing not just on building features, but also on delivering high-performance applications. Consistency beats intensity. 💬 Comment “Lazy” if you’re using lazy loading in your React apps 👇 👍 Like & share to support this learning journey! #30DaysOfReact #ReactJS #CodeSplitting #LazyLoading #FrontendDevelopment #WebDevelopment #JavaScript #MERNStack #LearnInPublic #100DaysOfCode ✨ Day 28 complete.

React Hooks — The Concept That Changed How I See React Components When I first started learning React, components felt like just UI blocks. But then I discovered Hooks… And suddenly, components became smarter, cleaner, and easier to manage. ✅ What are React Hooks? Hooks let you use state and lifecycle features inside functional components. In simple terms: 👉 Hooks allow components to store data, react to changes, and control behavior Without writing class components. 🔹 Most Common Hooks Every Beginner Learns useState → To store and update data Example: const [count, setCount] = useState(0); Used for: • Button counters • Form inputs • UI state useEffect → To handle side effects Example: useEffect(() => { console.log("Component loaded"); }, []); Used for: • API calls • Loading data • Running logic on update useRef → To access or store values without re-render Used for: • Accessing DOM elements • Persisting values 🔹 Why Hooks are Powerful Hooks make components: • Cleaner • Easier to read • Easier to maintain • More reusable 💡 My learning moment Before Hooks, logic and UI felt tightly connected. With Hooks, logic became reusable and structured. It made React feel more predictable and developer-friendly. If you're learning React, mastering Hooks is a major turning point. Which hook did you learn first — useState or useEffect? 👇 #React #ReactJS #FrontendDevelopment #JavaScript #WebDevelopment #LearningJourney #FullStackDeveloper #SoftwareEngineering
