🚀 Learn ReactJS — Day 5 Deep dive into Performance & Advanced State Hooks — making React apps faster, smarter, and easier to manage. This session focuses on optimizing renders and handling complex state logic cleanly. ✅ useMemo — Optimizing Heavy Calculations ✔ Stores the result of a calculation ✔ Reuses previous result if dependencies don’t change ✔ Prevents unnecessary recalculations on re-render ✔ Improves performance when working with expensive operations 💡 When to use ✔ Filtering large lists ✔ Complex calculations ✔ Derived data from props/state ✔ Performance optimization in large components 📌 Real-time example In a supplier list page (like your ViewSupplier structure), filtering thousands of records every render can slow UI. useMemo recalculates only when the list changes. ✅ useCallback — Preventing Unnecessary Re-renders ✔ Memorizes a function reference ✔ Returns same function unless dependencies change ✔ Prevents child component re-render caused by new function instance 💡 When to use ✔ Passing functions to child components ✔ Optimized components (React.memo) ✔ Event handlers in frequently re-rendering components ✔ Performance-sensitive UI 📌 Real-time example In your Header menu system, event handlers passed to menu items should not recreate every render. useCallback keeps the same function reference → smoother UI. ✅ useReducer — Managing Complex State Logic ✔ Manages state using a reducer function ✔ Updates state through actions ✔ Centralizes and organizes state logic ✔ Best for complex workflows 💡 When to use ✔ Multiple related state values ✔ State transitions based on conditions ✔ Form handling with validation ✔ Business logic-heavy components 📌 Real-time example Your Forgot Password flow: email → OTP → new password → confirm password Multiple steps + conditions → perfect useReducer use case. 💡 Key Learning React is not just about rendering UI — it’s about rendering efficiently. These hooks help control re-renders, optimize performance, and manage complex logic in a clean, scalable way.

🚀 React Learning Update: Built a Password Generator Today I built a Password Generator using React while practicing some core React hooks and concepts. It has a simple UI, but the goal was to understand how things work behind the scenes. Even though the interface is minimal, I learned a lot while building it. 🔧 Concepts I practiced: • useState – managing password length, numbers, and special characters • useCallback – optimizing functions like password generation and copy logic • useEffect – automatically regenerating password when options change • useRef – selecting the password field for clipboard copy • Clipboard API – copying generated password with one click ⚙️ Features: • Adjustable password length (6–100) • Option to include numbers and special characters • Instant password generation when settings change • Copy to clipboard functionality The UI is simple, but projects like this really help in understanding how React hooks work together and how state updates affect the UI. Every small project is a step forward in the journey of becoming a better developer. 💻🔥 #React #JavaScript #FrontendDevelopment #WebDevelopment #ReactHooks #BuildInPublic #CodingJourney #100DaysOfCode

🚀 React.js Basics: Understanding Props vs State While learning and building projects in React.js, one of the most important concepts to understand is the difference between Props and State. 🔹 State Managed inside the component Can change over time Used for dynamic data like counters, forms, UI updates 🔹 Props Passed from parent to child components Read-only (cannot be modified by the child) Used to share data between components 💡 Simple way to remember: State = Internal data of a component Props = Data passed from parent component Understanding these two concepts clearly helps in building clean, reusable, and scalable React components. I created this visual to make the concept easier for beginners who are learning React UI Development. 🌐 Explore my work: https://allconverthub.com https://lnkd.in/g4Hnzt9Z #ReactJS #FrontendDevelopment #UIDeveloper #JavaScript #WebDevelopment #ReactLearning #FrontendEngineer #Coding

🚀 7 Reasons Why React is So Powerful React is everywhere. But understanding why it works so well is what separates beginners from real developers. Here are 7 core features that make React stand out: 🔹 Virtual DOM Updates only the changed parts of UI → faster performance and smoother user experience. 🔹 Component-Based Architecture Break UI into small reusable pieces → clean, scalable, and maintainable code. 🔹 Reusability Write once, reuse across the app → faster development and consistency. 🔹 JSX (JavaScript XML) Write HTML-like code inside JavaScript → improves readability and developer productivity. 🔹 Declarative Approach Focus on what the UI should look like → React handles the updates efficiently. 🔹 Strong Ecosystem Huge community, tools, and libraries → faster problem solving and development. 🔹 Hooks Simplify state and lifecycle management → cleaner and more powerful functional components. — Anuj Pathak #reactjs #javascript #webdevelopment #frontenddevelopment #softwareengineering #developersoflinkedin #programming #coding #techlearning #learninginpublic #buildinpublic

🚀 Today I Learned: React Lifecycle (Class vs Functional Components) Today I spent some time understanding how React components live, update, and disappear inside an application. This concept is called the React Lifecycle. Every component in React goes through three main phases: 🔹 Mounting – When a component is created and added to the DOM for the first time. In class components this involves steps like the constructor, rendering the UI, and then running logic after the component is mounted. 🔹 Updating – This phase happens whenever state or props change. React re-renders the component and updates the DOM with the new changes. 🔹 Unmounting – This is when a component is removed from the DOM. Any cleanup logic should happen here. One interesting thing I realized is how functional components handle lifecycle differently compared to class components. Instead of multiple lifecycle methods, functional components mainly rely on effects and dependencies to control behavior during mounting, updating, and unmounting. 💡 My key takeaway today: Even though the implementation looks different in class and functional components, the core lifecycle phases remain the same — Mount → Update → Unmount. Understanding this makes it much easier to reason about when and why React components run certain logic. Learning React step by step and connecting these concepts is starting to make the framework feel much more intuitive. #ReactJS #FrontendDevelopment #JavaScript #WebDevelopment #LearningInPublic #100DaysOfCode #DeveloperLife #Coding #BuildInPublic #CodingChallenge #FrontendDeveloper #DeveloperJourney #WebDevCommunity #MERNStack #Consistency #TechLearning #FullStack

Introducing bxp-code v1.0.0 — drop-in React code blocks for developers I built a VS Code theme extension (BedarX Pro) and wanted the same syntax colors on the web. Every React highlighting library I tried looked nothing like my editor, needed too much config, or produced flat output. So I built bxp-code. Drop-in React components with VS Code-accurate syntax highlighting via Shiki (same TextMate grammars VS Code uses) and automatic Prettier formatting. No setup needed. Two components: 1. BxpCode — code block with header, copy button, line numbers, sticky headers 2. BxpCodeTabs — tabbed interface for multi-language snippets Why use it: Building docs, portfolios, blogs, tutorials, or any React app showing code? This replaces wiring up a highlighter, formatter, copy button, and theme system separately. One import, one component. Dark/light themes included, every color customizable via props. Accepts code as string, File, or URL with auto language detection. What's next: Vue and Svelte adapters, React Native support, diff highlighting, and more built-in themes. The goal — the go-to code block component across frontend frameworks. npm install bxp-code npm: https://lnkd.in/dcZW7J5v Docs: https://lnkd.in/dVqcqN-z Playground: https://lnkd.in/dGX-4zbZ GitHub: https://lnkd.in/d2qPCt3e The VS Code theme it was born from: https://lnkd.in/dPZpgA23 A star or share goes a long way.

⚛️ Why React became one of the most popular tools for building modern web applications When I first started learning frontend development, one thing quickly became clear: As applications grow, managing the UI becomes harder and harder. Updating elements, handling state, keeping everything synchronized… it can easily turn into messy code. This is exactly where React shines. 🚀 Instead of thinking about the page as one big structure, React encourages developers to break the UI into small reusable components. For example: A page can be built from simple pieces like: 🔹 Navbar 🔹 Sidebar 🔹 Product Card 🔹 Button 🔹 Modal Each piece becomes its own component, which makes the application easier to manage and scale. Another powerful idea React introduced is state-driven UI. Instead of manually manipulating the DOM, you simply update the state, and React automatically updates the UI. Example: const [count, setCount] = useState(0); Whenever the state changes, the interface updates automatically. This approach makes applications: ✅ Easier to maintain ✅ Easier to scale ✅ More predictable Over time, I realized that learning React is not just about learning a library — it's about learning a better way to think about building user interfaces.

Frontend Learning — Don’t Mutate State Directly As frontend developers, we sometimes update state directly… especially with objects or arrays. It might seem to work, but it can break your UI in unexpected ways. Why this is a problem: -> React may not detect changes -> UI might not re-render -> Leads to unpredictable bugs -> Breaks immutability principles 💡 Key Takeaway: Always create a new copy of state instead of mutating it. ⚡ Common Mistake: Directly modifying state ✅ Better Approach: Use immutable updates #ReactJS #FrontendDevelopment #JavaScript #WebDevelopment #CleanCode #BestPractices #CodingTips #LearnInPublic #DeveloperJourney

Learning React made me realize something — frontend isn’t about “changing elements.” It’s about controlling state and thinking in systems. Once that clicked, everything started making sense. Still early in the journey, but the foundation is getting stronger every day. Next stop: advanced hooks and performance optimization.
