Day 6 - Frontend Diaries 👉 I thought clicking a button is a simple action While working on frontend, my thinking was straightforward user clicks a button action gets triggered and that’s it But in real scenarios, it’s not that simple ▪️ What if the user clicks multiple times? ▪️ What if the request is still in progress? ▪️ What if the same action gets triggered again before the first one completes? I started noticing unexpected behavior like: ▪️ duplicate requests ▪️ multiple API calls ▪️ and inconsistent state That’s when I realized a button click is not just an event it’s something that needs to be controlled Disabling the button during loading preventing repeated actions handling user interaction carefully Frontend is not just about responding to clicks it’s about controlling how those interactions happen #frontenddevelopment #reactjs #webdevelopment #fullstackdeveloper #softwareengineering #buildinpublic #developers

𝗦𝗼𝘂𝗻𝗱 𝗳𝗮𝗺𝗶𝗹𝗶𝗮𝗿? • Props drilling through multiple layers • Random re-renders slowing everything down • Fixing one bug creates another • Global state turning into a dumping ground • Using state where simple logic would work Clean frontend isn’t about adding more tools. It's about reducing and structuring state the right way. Simpler state = scalable, maintainable apps. Build clean, scalable #frontends with Atlantis Tech.

#ReactJS has become one of the core technologies in modern user interface development, thanks to the flexibility it offers in building applications, organizing components, and managing interactive interfaces in a way that supports scalability and maintainability. In this presentation, I share an overview of several fundamental ReactJS concepts, starting from the core structure and workflow of React applications, through Components, Props, State, JSX, and Routing, to Virtual DOM, Redux, and selected practices related to performance optimization and data flow management. The presentation is intended to provide a clear and structured view of React fundamentals, helping learners and developers build a connected understanding of the concepts that shape modern front-end applications. #ReactJS #FrontendDevelopment #WebDevelopment #JavaScript #SoftwareDevelopment #UIDevelopment

🚀 Ever wondered what really happens behind the scenes in React? We’ve published a deep-dive guide that breaks down how React works internally beyond just components and props. From the Virtual DOM to the reconciliation algorithm, and from the powerful Fiber architecture to rendering phases and hooks, this blog explains how React efficiently updates the UI while keeping performance optimized. Whether you're building scalable applications or looking to strengthen your fundamentals, this guide offers clear, real-world insights into React’s core mechanics. 💡 Learn how React makes smart decisions to update only what’s necessary and why it matters for your applications. 👉 Read the full blog by Sachin Saxena and level up your React expertise: https://lnkd.in/gzTQaAj3 #ReactJS #WebDevelopment #Frontend #JavaScript #SoftwareEngineering #Performance #TechBlog

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 𝟱 𝗼𝗳 𝗠𝘆 𝗥𝗲𝗮𝗰𝘁 𝗝𝗼𝘂𝗿𝗻𝗲𝘆 ⚛️🚀 Today I explored what happens 𝗯𝗲𝗵𝗶𝗻𝗱 𝘁𝗵𝗲 𝘀𝗰𝗲𝗻𝗲𝘀 𝗶𝗻 𝗥𝗲𝗮𝗰𝘁 — 𝗥𝗲𝗰𝗼𝗻𝗰𝗶𝗹𝗶𝗮𝘁𝗶𝗼𝗻, 𝗙𝗶𝗯𝗲𝗿, 𝗗𝗶𝗳𝗳𝗶𝗻𝗴, 𝗮𝗻𝗱 𝗞𝗲𝘆𝘀. I learned that when state changes, React doesn’t update the whole DOM. Instead, it compares the previous and new Virtual DOM using a 𝗱𝗶𝗳𝗳𝗶𝗻𝗴 𝗮𝗹𝗴𝗼𝗿𝗶𝘁𝗵𝗺, and updates only what actually changed. The idea of 𝗥𝗲𝗰𝗼𝗻𝗰𝗶𝗹𝗶𝗮𝘁𝗶𝗼𝗻 — deciding what needs to update — was really interesting. And 𝗥𝗲𝗮𝗰𝘁 𝗙𝗶𝗯𝗲𝗿 takes it further by making rendering more efficient and interruptible, so the UI stays smooth. Also understood why 𝗸𝗲𝘆𝘀 are important when rendering lists. They help React identify elements correctly and avoid unnecessary re-renders. It’s fascinating to see how much optimization is happening behind such simple code. React is smarter than it looks 💻⚡ #ReactJS #JavaScript #WebDevelopment #LearningJourney #FrontendDevelopment

Most React developers don’t have a knowledge gap. They have a structure gap. After 5+ years working in frontend (UI/UX → development → leading projects), I’ve seen this again and again: 👉 People know React 👉 But struggle to build real, production-ready apps Because tutorials teach syntax, not how to think The structure that actually matters 👇 1. Foundations → JSX + Virtual DOM → Components, Props, State 2. Hooks (in real priority order) → useState → useEffect → useContext → useMemo → useCallback 3. Real-world patterns → Routing (React Router) → Forms + validation → API calls (loading, error, retry states) 4. Performance → Memoization (React.memo, useMemo) → Avoiding unnecessary re-renders → Code splitting & lazy loading 5. Production readiness → TypeScript with React → Testing (React Testing Library + Jest) → State management (Zustand / Redux Toolkit) 💡 The real gap is here: I know React ❌ I can ship real apps ✅ What actually works 👇 → Pick ONE weak area → Go deep into it → Build something real That’s how you level up. #ReactJS #WebDevelopment #JavaScript #FrontendDeveloper #MERNStack #CareerGrowth

🚀 How I Build a New Feature in React (My Workflow) Over time, I’ve developed a simple and effective process for building React features that keeps my code clean, scalable, and performance-friendly. Here’s how I approach it #1 Understand Requirements Before writing any code, I make sure I fully understand the feature — user needs, edge cases, and expected behavior. #2 Plan Components I break the feature into small, reusable components. This helps maintain clean architecture and makes future updates easier. #3 Create API Integration I connect the frontend with APIs, handle requests properly, and ensure error handling is in place. #4 Handle State Management I decide whether to use local state, context, or a state library based on the complexity of the feature. #5 Optimize Performance I avoid unnecessary re-renders, use memoization when needed, and ensure smooth user experience. @ A good workflow not only speeds up development but also improves code quality and maintainability.

Day 13 - Frontend Diaries 👉 I thought state updates happen instantly While working with state, my understanding was simple update the state and the new value should be available immediately So I would update state and then try to use that updated value in the next line But things mostly don't behave the way I expected Sometimes the value was still the old one sometimes multiple updates didn’t reflect correctly That’s when I realized state updates are not applied instantly They are scheduled and sometimes batched together React waits and processes them in a way that keeps things efficient Which means you can’t always rely on state being updated right after setting it You have to think in terms of the next render not the current line of code That small shift in understanding explains a lot of unexpected behavior #frontenddevelopment #reactjs #webdevelopment #fullstackdeveloper #softwareengineering #buildinpublic #developers

One thing I truly appreciate about React is how it completely changes the way we think about building user interfaces. Instead of dealing with a huge, complex page, React allows us to break everything down into small, reusable components. Each component handles its own logic and UI, making the entire application more structured and easier to manage. This approach has made frontend development much more: • Organized – No more messy, hard-to-track code • Reusable – Write once, use multiple times • Maintainable – Fix or update one component without affecting the whole app What I found most interesting is how this component-based architecture feels similar to building blocks. You simply create small pieces and combine them to build something powerful and scalable. As someone learning frontend development, this concept has made projects much more enjoyable and less overwhelming. Still exploring more of React, but this is definitely one of the features that stood out for me 🚀 #ReactJS #FrontendDevelopment #WebDevelopment #LearningJourney #JavaScript #Coding
