React & Redux Learning Portal: Master Modern State Management

🚀 Unlock Your React Potential with Hands-On Learning 👉 Most developers don’t struggle with React Hooks because they’re hard — they struggle because learning is not interactive enough. Docs and tutorials explain what hooks do, but rarely help you experiment, visualize, and apply them in real scenarios. So I built React Hooks Learning Platform 🎯 A structured, hands-on platform to learn React Hooks the way they’re meant to be learned — by doing. 🔍 What makes it different? ✅ Structured learning paths (Beginner → Advanced) ✅ Progress tracking & achievements ✅ Best practices & real-world patterns ✅ Common mistakes explained clearly 🧠 Hooks covered useState, useEffect, useContext, useReducer useCallback, useMemo, useRef, useTransition Custom Hooks 🔗 Start learning: https://react.thedroid.in 📩 Contact: rohanujagare24@gmail.com Would love feedback from the React community 🙌 Which React Hook did you find hardest to understand when you started? #React #ReactHooks #FrontendDevelopment #JavaScript #WebDevelopment #BuildInPublic #FrontendDeveloper

🚀 Started Learning React – Day 2 Learning Notes Continuing my React learning journey, here’s what I explored and understood on Day 2, explained in a simple and practical way for beginners 👇 🔹 1. Why Environment Setup is Important? Before writing React code, a proper development environment is required for smooth development, debugging, and scalability. 🔹 2. What is Node.js and npm? Node.js is a JavaScript runtime used to run JavaScript outside the browser. npm (Node Package Manager) helps install, manage, and update project dependencies. React development relies heavily on npm. 🔹 3. Essential Tools for React Development Node.js (v20+) npm (v10+) Visual Studio Code (VS Code) Useful VS Code Extensions: Live Server Live Preview IntelliSense for CSS class names VS Code Icons GitHub Copilot 🔹 4. Creating a Basic Web Application Structure Initialized project using npm init -y Understood the role of: README.md (project documentation) .gitignore (ignore unnecessary files in Git) public folder (static files) src folder (dynamic resources) index.html (entry point) 🔹 5. Running the Project Locally Used Live Server to run the application Accessed the app via localhost This helped understand how a browser loads a web app. 🔹 6. How to Enable React in an HTML Page To use React, we need to include: React (core library) ReactDOM (Virtual DOM handling) Babel (to use JSX in browser) These can be added via CDN links for learning purposes. 🔹 7. Virtual DOM vs Actual DOM React creates a Virtual DOM Compares changes efficiently Updates only the required parts of the Actual DOM Result: Faster and smoother UI rendering 🔹 8. Rendering in React 18+ React 18 uses a new rendering approach: ReactDOM.createRoot() root.render() This improves performance and future scalability. 🔹 9. Key Learnings from Day 2 ✅ React can run directly in the browser ✅ Fundamentals matter before using frameworks ✅ Understanding how React renders UI is critical ✅ Strong basics lead to better projects later 📌 Day 2 complete. 🚀 If you’re also learning React or planning to start, feel free to connect 🤝 #ReactJS #WebDevelopment #FrontendDevelopment #LearningJourney #JavaScript #SPA #Day1Learning #DeveloperCommunity #TechLearners #ReactBeginners #LearnReact #BuildInPublic #DailyLearning #TechCommunity

🚀 My React JS Learning Journey Today, I explored Class Component Lifecycle Methods and understood how a React component lives, updates, and exits the DOM. 🔄 React Class Component Lifecycle Phases 1️⃣ Mounting Phase ➡️ When a component is created and inserted into the DOM 🔹 constructor() – Initialize state & bind methods 🔹 render() – Returns JSX 🔹 componentDidMount() – Perfect for API calls & side effects 2️⃣ Updating Phase ➡️ When state or props change 🔹 shouldComponentUpdate() – Controls re-rendering 🔹 render() – Re-renders UI 🔹 componentDidUpdate() – Responds to state/prop changes 3️⃣ Unmounting Phase ➡️ When a component is removed from the DOM 🔹 componentWillUnmount() – Cleanup (timers, subscriptions) 💡 Key Takeaways ✔️ Lifecycle methods help manage data fetching, performance, and cleanup ✔️ Understanding these phases builds a strong React foundation ✔️ Makes the transition to Hooks (useEffect) much easier 📌 Learning React step by step and enjoying the journey! 📈 More updates coming soon… #ReactJS #FrontendDevelopment #WebDevelopment #JavaScript #LearningJourney #ClassComponents #ReactLifecycle 10000 Coders

🚀 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

React Learning Journey Update: Built a food ordering app that serves bugs faster than meals! Just wrapped up a practice project called "Algorithm Meals" and wow, the real meal was the bugs I debugged along the way! What I practiced: React Context API (goodbye prop drilling hell!), useReducer hook (my brain still reducing), Shopping cart logic (add/remove items like a pro, eventually), CSS animations (making buttons go boop), Component architecture (organising chaos, one folder at a time) Plot twist, The bugs that humbled me: Spent 3 hours wondering why my input wasn't working. Turns out ref: {myRef} is NOT the same as ref: myRef. Who knew? (Everyone. Everyone knew.). Created empty functions and wondered why nothing happened. Apparently computers need ACTUAL instructions. Forgot to implement the REMOVE action in my reducer. Items went in but never came out. Hotel California for shopping carts. What I learned: Reading error messages > assuming I know what's wrong Console.log is my best friend (sorry, actual friends) Practice projects teach you what tutorials can't: patience Breaking things is part of building things Tech Stack: React | Context API | useReducer | CSS Modules | Trial & Error. This was a practice app, not a production app, but I'm proud of every bug I squashed! To everyone learning React: you're not alone in the struggle. #ReactJS #LearningToCode #WebDevelopment #JavaScript #CodeNewbie #LearningInPublic #PracticeProject #DebuggingLife

⚛️ React Learning Series - Day 14 (Project Day) Today, I built an amazing Todo application called TaskTracker - Smart Todo App. I’m really excited to share it with you all. Let’s take a look at its key features: ✨ Features ✔️ Clean and modern UI ✔️ Local Storage support (main feature) ✔️ Shows current date and time ✔️ Clear All button - remove all tasks in one click ✔️ Option to delete a specific task ✔️ Completion button to mark tasks as completed ✔️ Validation - ignore adding duplicate or empty tasks 📚 What I Learned In this mini project, I learned the basics of how React works, including Hooks and localStorage. localStorage stores data in key-value pairs and saves important data locally in the browser for a specific domain. 🧩 Common localStorage Methods • localStorage.setItem("key_name", "value"); → Create or update data • localStorage.getItem("key_name"); → Get stored data • localStorage.removeItem("key_name"); → Remove a specific item • localStorage.clear(); → Remove all stored data ⚠️ Note: localStorage does not work in Incognito or Private browsing mode. 🔗 Live Project: https://lnkd.in/gBndc2kW 👋 GitHub Repo: https://lnkd.in/g3x4k-eB #ReactJS #WebDevelopment #FrontendDeveloper #JavaScript #LearningInPublic #CodingJourney #FullStackDeveloper #ReactProjects #100DaysOfCode #AmanKumar

🚀 Day 105 of My Web Development Journey, Cohort 2.0 (Sheryians Coding School) Continuing with our Instagram Clone project and improving the backend architecture. We had already built controllers to: • create a post • fetch all posts of the logged-in user • fetch a specific post Today we noticed one thing that the same user identification logic was repeating in all controllers. This logic included: getting token from cookies, verifying it and extracting user ID Repeating code is not efficient and not scalable Solution: Authentication Middleware We moved this logic into a middleware. New flow: Request → Router → identifyUser middleware → Controller middleware verifies token → attaches user info to req.user → controller simply uses req.user.id Scaling Social Features (Concept) We also discussed how features like followers & following should not be stored inside a user document (MongoDB has a 16MB document limit). Instead, use an Edge Collection to store relationships between users. Key Learnings  • Avoid repetition using middleware • Understand request flow in Express • Write scalable & maintainable backend code • Edge collections help model relationships efficiently • Remember the flow, not the code Stay tuned 🔥 ❤️ #WebDevelopment #Cohort2 #SheryiansCodingSchool Sheryians Coding School Community #LearningInPublic #HTML #CSS #SCSS #FrontendDevelopment #BackendDevelopment #FullStackDevelopment #LearningJourney #ReactJS #TailwindCSS
