From Design to Development: Lessons Learned Building Real Products

⚛️ Frontend Dev Series (Part 13): Things I Wish I Knew About useEffect Sooner If you’ve ever crashed your React app because of useEffect()… welcome to the club. 😅 I learned this hook the hard way — and I wish someone had explained it like this 👇 🔹 1️⃣ useEffect ≠ Lifecycle It’s not the new componentDidMount. It’s for side effects — anything that happens because state or props changed. 🔹 2️⃣ The Infinite Loop Trap When useEffect() updates a state that’s also in its dependency array → BOOM 💥 Infinite renders. Fix: Never trigger what you’re depending on. 🔹 3️⃣ The Dependency Array Rule [] → run once [value] → run when value changes No array → run every render. Miss this = chaos. 🔹 4️⃣ Timing Matters useEffect runs after render. That’s why you sometimes see flickers or incomplete UI before data loads. Need sync behavior? Use useLayoutEffect. 🔹 5️⃣ Cleanup is Key Always clean your mess. Unsubscribe from listeners, clear intervals, abort fetches — or you’ll create invisible memory leaks. 🔹 6️⃣ The Real Purpose useEffect connects React to the outside world — APIs, events, sockets, DOM, etc. It’s not for every little logic you can think of. 💭 Final Thought: The best React devs don’t use useEffect everywhere. They avoid needing it through cleaner architecture. 💬 What’s the worst useEffect bug you’ve ever faced? 👇 Drop your experience in the comments. 🔁 Tag a React dev who still fears dependency arrays. 📌 Save this before your next build. #ReactJS #FrontendDevelopment #WebDevelopment #CleanCode #JavaScript #ReactTips #WebDev #CodingJourney #DevCommunity #BuildInPublic #useEffect #ReactHooks

If you’re curious like me about how frontend web frameworks are built or how they work under the hood, this book is a great read “Build a Frontend Web Framework (From Scratch)”. I really enjoyed reading it! It’s fun, surprisingly comprehensive, and gives a clear mindset about what’s happening behind tools like React, Vue, or Svelte. It’s not about creating a production framework, it’s about learning by building, from the DOM to virtual DOM, state management, and reconciliation algorithms. Here’s a summary and key takeaways: 1. Frameworks aren’t magic Frameworks automate repetitive, low-level DOM work. When you build one from scratch, you realize they’re just organized layers of abstraction, not magic. 2. Start from the roots You begin by coding a small app with vanilla JavaScript, manually updating the DOM to understand what problems frameworks solve. 3. Virtual DOM & Reconciliation You then build a virtual DOM, a lightweight JS representation of the actual DOM. You learn how frameworks diff (compare) two virtual trees to apply minimal updates to the browser DOM, the same concept React uses. 4. State Management The book teaches a reducer-based state manager, similar to Redux’s idea: Centralized state Dispatch actions → reducers update state → re-render the view 5. Components You build functional and class-based components that: Hold their own state Re-render when state changes Can nest inside each other and communicate via props and events 6. Lifecycle & Scheduler Later chapters add lifecycle hooks (onMounted, onUnmounted) and an async scheduler to coordinate rendering, similar to Vue’s nextTick or React’s reconciliation cycle. 7. Advanced Concepts You also explore: Keyed lists (for efficient updates) Component communication Testing asynchronous components and extras like routing and slots in the GitHub wiki.

💻 Frontend is not easy. Many people think frontend development is “simple.” Just a few buttons, some CSS, and done — right? 😅 But the truth is, modern frontend development is hard. Before you even touch React, you need to understand: 🧠 How JavaScript really works (scope, closures, async, promises) ⚙️ How to structure complex UI logic ⚙️ How to manage state efficiently (Redux, Context, etc.) 🚀 How to handle performance, accessibility, and responsive design ⚙️ How to keep everything maintainable for the next developer On my journey as a developer, I’ve realized something important 👇 The core principles of programming and computer science apply to both frontend and backend — and to every language. Whether you’re building UI components or server logic, the fundamentals matter. If you skip them, no framework can save your code. 🎨 Frontend isn’t just about making things look good — it’s about making them work well, scale smoothly, and feel seamless to users. Frontend is engineering, not decoration. Understanding that difference turns coding into craftsmanship. So if you’re starting out — don’t skip JavaScript, and don’t skip the basics. They’re the foundation of everything we build. 💪 #FrontendDevelopment #JavaScript #React #WebDevelopment #CodingJourney #TejramPaswan

Before you even touch React, you need to understand: 🧠 How JavaScript really works (scope, closures, async, promises) 🧩 How to structure complex UI logic ⚙️ How to manage state efficiently (Redux, Context, etc.) 🚀 How to handle performance, accessibility, and responsive design 🧱 And how to keep everything maintainable for the next developer On my path to programming, I’ve realized something important 👇 The core principles of computer science and programming apply to both frontend and backend — and to any language. Whether you’re building UI components or server logic, the fundamentals matter. If you don’t understand them, you’ll likely end up writing bad code, no matter the framework or stack. 🎨 Frontend is not just about making things look nice — it’s about making them work well, scale, and feel seamless to users. Frontend is engineering — not decoration. And understanding that difference is what separates coding from craftsmanship. So if you’re starting out, don’t skip JavaScript — and don’t skip the basics.
