React Hooks: useEffect vs useLayoutEffect Timing

Today I explored some core concepts of React that changed the way I see frontend development : • How React works behind the scenes • Rendering process in React • Virtual DOM vs Real DOM • Diff Algorithm (how react updates efficiently) • Client Side Rendering (CSR) • Server Side Rendering (SSR) One thing I found really interesting is how React uses the virtual DOM and diff algorithm to update only the necessary parts of the UI, making apps faster and more efficient. I'm excited to dive deeper and build more projects using these concepts! #React #Javascript #MernStackDevelopment

🚀 Day 4 of Building React Projects Today I built a Background Changer Application using React.js. This project allows users to change the background color of the webpage dynamically with a single click. ✨ Features: • Change background color instantly • Interactive buttons for different colors • Simple and clean UI 🛠 Tech Stack: React.js JavaScript HTML CSS 🌐 Live Demo: https://lnkd.in/daCYux9G 💻 Source Code: https://lnkd.in/dEJDyd9G #ReactJS #JavaScript #FrontendDevelopment #WebDevelopment #LearningInPublic

🚀 Built a Simple OTP Generator using React! I recently worked on a small project to strengthen my understanding of React hooks, especially useState and useEffect. 🔐 Project Highlights: Generates a secure 6-digit OTP Countdown timer (5 seconds) for OTP expiry Auto-disables the button during active timer Displays expiry message once time runs out Clean and interactive UI 💡 What I learned: Managing state effectively with useState Handling side effects and timers using useEffect Writing clean and testable React components Improving user experience with conditional rendering This project may be simple, but it helped me understand how real-world features like OTP systems work behind the scenes. Looking forward to building more such practical projects! 💻✨ #ReactJS #WebDevelopment #Frontend #JavaScript #LearningByDoing #CodingJourney

🚀 Day 9 of Building React Projects Today I built a Login & Registration System using React.js. This project focuses on user authentication flow where users can register, log in, and manage their access with a simple and responsive UI. ✨ Features: • User Registration • User Login Authentication • Form validation • Error handling for invalid inputs • Responsive UI 🛠 Concepts Used: • React Hooks (useState) • Form Handling • Conditional Rendering • Basic Authentication Logic 💻 Tech Stack: React.js JavaScript HTML CSS 🔗 GitHub Repository: https://lnkd.in/dDTrzHXW #React #JavaScript #WebDevelopment #FrontendDevelopment #LearningInPublic #ReactProjects

⚛️ How React Works (Virtual DOM Explained) React improves performance by using a concept called the Virtual DOM. Instead of updating the entire UI, React: • Creates a virtual copy of the DOM • Compares it with the previous version • Finds only the changes (diffing) • Updates only the necessary parts This makes React fast and efficient for building modern user interfaces. 👉 Smart updates = Better performance Have you used Virtual DOM in your projects? #ReactJS #FrontendDevelopment #JavaScript #WebDevelopment #SoftwareEngineering

Why is React so fast compared to normal DOM manipulation?" 🤔 The answer lies in the Virtual DOM ⚡ Let’s break it down simply 👇 🔹 What is Virtual DOM? Virtual DOM is a lightweight copy of the real DOM. Instead of updating the real DOM directly, React first updates the Virtual DOM. 🔹 How does it work? 1. React creates a Virtual DOM 2. When state changes → new Virtual DOM is created 3. React compares it with the previous one (diffing) 4. Only the changed parts are updated in the real DOM 🔹 Why is it faster? 👉 Real DOM updates are slow 👉 Virtual DOM minimizes unnecessary updates 💻 Example concept: Instead of updating the entire UI, React updates only the part that actually changed. 🚀 Pro Tip: Efficient rendering is the reason React apps feel fast and smooth. 💬 Did you know this is how React optimizes performance? #reactjs #javascript #webdevelopment #mern #developers

🚀 Day 6 of Building React Projects Today I built a Notes Application using React.js. This project allows users to create, edit, and delete notes while saving the data in the browser using LocalStorage. ✨ Features: • Add new notes • Edit existing notes • Delete notes • Save notes in LocalStorage • Simple and responsive UI 🛠 Tech Stack: React.js JavaScript HTML CSS 🌐 Live Demo: https://lnkd.in/dVWH9WBf 💻 Source Code: https://lnkd.in/ddGADSFQ #ReactJS #JavaScript #FrontendDevelopment #WebDevelopment #LearningInPublic

🎨 React Background Color Changer Project Built a simple yet interactive Background Color Changer using React.js, focusing on state management and dynamic UI updates. This project helped me understand how to: 🔹 Use useState hook for managing color state 🔹 Update UI dynamically on button click 🔹 Handle events and improve user interaction 🔹 Write clean and reusable React components A great hands-on practice to strengthen core React concepts while building something visual and interactive. Small projects like this build a strong foundation for creating real-world applications 🚀 #ReactJS #JavaScript #FrontendDevelopment #WebDevelopment #LearningJourney #100DaysOfCode

✨ 𝗗𝗮𝘆 𝟰 𝗼𝗳 𝗠𝘆 𝗥𝗲𝗮𝗰𝘁 𝗝𝗼𝘂𝗿𝗻𝗲𝘆 ⚛️🚀 Today I learned about the `𝘂𝘀𝗲𝗘𝗳𝗳𝗲𝗰𝘁` 𝗵𝗼𝗼𝗸, and more importantly, 𝘄𝗵𝘆 𝘄𝗲 𝗮𝗰𝘁𝘂𝗮𝗹𝗹𝘆 𝗻𝗲𝗲𝗱 𝗶𝘁. While working with React, I noticed that components are mainly for rendering UI. But sometimes we need to do things outside rendering — like fetching data, setting up timers, or updating something after the UI changes. That’s where `𝘂𝘀𝗲𝗘𝗳𝗳𝗲𝗰𝘁` comes in. It lets us handle these 𝘀𝗶𝗱𝗲 𝗲𝗳𝗳𝗲𝗰𝘁𝘀 in a clean and controlled way. What I found interesting is how it runs after render and can depend on specific values. Instead of mixing everything together, React separates 𝗨𝗜 𝗹𝗼𝗴𝗶𝗰 from 𝘀𝗶𝗱𝗲 𝗲𝗳𝗳𝗲𝗰𝘁𝘀, which makes the code easier to understand and manage. Starting to see how React keeps things structured as apps grow 💻⚡ #ReactJS #JavaScript #WebDevelopment #LearningJourney #FrontendDevelopment
