React Fundamentals: Declarative Thinking & State Management

What Are React Hooks? ⚛️ React Hooks changed the way we build components making code cleaner, more reusable, and easier to manage. In simple terms, React Hooks let you use state and other React features without writing a class component. 🔹 Common Hooks: • useState – Manage state in functional components • useEffect – Handle side effects (API calls, updates) • useContext – Share data across components • useRef – Access DOM elements directly 🔹 Why Hooks Matter: • Cleaner and more readable code • Better logic reuse • Simplified state management • Faster development Hooks aren’t just a feature they’re a shift toward modern React development. If you’re still relying on class components… it’s time to upgrade 🚀 #ReactJS #WebDevelopment #JavaScript #Frontend #Programming #ReactHooks

Just shared a new article on Medium about React Custom Hooks! 🚀 As React developers, we often struggle with bloated components. Custom Hooks are a game-changer for extracting reusable logic and keeping our codebase DRY (Don't Repeat Yourself). In this article, I cover: ✅ What Custom Hooks are ✅ Building a reusable useFetch hook ✅ Best practices for clean code Check it out here: https://lnkd.in/g2Pp46As #ReactJS #WebDevelopment #JavaScript #Programming #Frontend #CodingTips

JavaScript vs. TypeScript: The 'Cocomelon' Edition! Ever feel like your JavaScript code is a bit... chaotic? Like a toddler running around with no shoes? That’s where TypeScript comes in! Think of JavaScript as the fun, flexible playground where you can build anything quickly. It’s dynamic, it’s fast, but sometimes things get messy. TypeScript is like adding a 'Safety Helmet' and 'Rules' to that playground. It’s a superset of JavaScript that adds Static Typing. Why make the switch? Catch Bugs Early: Find errors while you type, not when the app crashes. Better Tooling: Enjoy super-powered autocompletion in VS Code. Scalability: It makes large projects much easier for teams to manage. Is your team Team JS or Team TS?

Props vs State in React Most beginners get confused between Props and State in React. At first, both seem similar because both store data. But the real difference is simple: * Props = Data received from another component * State = Data managed inside the component Example: function Parent() { return <Child name="Durgesh" />; } function Child(props) { return <h1>{props.name}</h1>; } Here, `name` is a prop because it comes from the Parent component. Now look at State: const [count, setCount] = useState(0); Here, `count` is managed inside the same component. Quick Difference 👇 • Props are read-only • State can be updated • Props come from parent to child • State belongs to the component itself Think like this: Props = Things you receive State = Things you control Once you understand this difference, React becomes much easier.

Why do we need to call 'super(props)' in the constructor of a React component? JavaScript classes aren't magic. They are just syntactic sugar over prototypes. If you are still using (or have used) Class Components in React, you have likely typed 'super(props)' a thousand times. But do you actually know what happens if you forget it? In JavaScript, you cannot use the keyword 'this' in a constructor until you have called the parent constructor. Since your component extends 'React.Component', calling 'super()' is what actually initializes the 'this' object. If you try to access 'this.state' or 'this.props' before that call, JavaScript will throw a ReferenceError and crash your app. But why pass 'props' into it? React sets 'this.props' for you automatically after the constructor runs. However, if you want to access 'this.props' inside the constructor itself, you must pass them to 'super(props)'. If you just call 'super()', 'this.props' will be undefined until the constructor finishes execution. Most of us have moved to Functional Components where this isn't an issue. But understanding these fundamentals is what separates a developer who just writes code from one who understands the runtime. #ReactJS #Javascript #SoftwareEngineering #WebDevelopment #Coding #ProgrammingTips

- One React Lesson That Made a Difference in How I Code When I first started using React, I used to put everything into one component — state, logic, and UI all mixed together. It worked… but it wasn’t scalable. Then I learned the importance of separation of concerns 👇 Now, I focus on: • Building reusable components • Moving logic into custom hooks • Keeping components clean and easy to read For example, instead of handling API calls inside components, I move them into custom hooks like "useFetch" or into service layers. This small shift made my code: ✔️ Easier to maintain ✔️ More reusable ✔️ Cleaner and more readable Good React code isn’t just about making things work — it’s about making them scalable. 💬 What’s one React concept that improved your code quality? #ReactJS #JavaScript #FrontendDevelopment #ReactNative #CleanCode #WebDevelopment #ReactHooks #CustomHooks #SoftwareEngineering #FrontendEngineer #CodeQuality #ScalableCode #Programming #DeveloperLife #BuildInPublic #LearnInPublic

React Hooks changed the way I write React forever. 🎣 Before hooks, I was juggling class components, lifecycle methods, and `this` bindings just to manage basic state. Then `useState` and `useEffect` walked in and said "relax, we got you." 😄 A few things I love about hooks: → `useState` — dead simple state management, no class needed → `useEffect` — handle side effects cleanly in one place → `useCallback` & `useMemo` — performance wins without the headache → Custom hooks — extract and reuse logic like a pro The best part? Your components become smaller, more readable, and actually fun to write. If you're still on class components, I genuinely encourage you to make the switch. The learning curve is worth it — I promise. 🙌 What's your favourite hook?

🚀 JavaScript: The Language That Powers the Modern Web Every website we interact with today — from simple landing pages to complex web applications — relies on JavaScript to bring ideas to life. What makes JavaScript powerful is its versatility: 🔹 Runs in every modern browser 🔹 Powers both frontend and backend development (Node.js) 🔹 Supports modern frameworks like React, Vue, and Angular 🔹 Enables scalable applications and real-time experiences For developers, learning JavaScript is more than learning a programming language — it’s entering an ecosystem that drives innovation across the web. As I continue building projects and strengthening my development skills, I’m constantly reminded that consistent practice and curiosity are the real accelerators in tech. 💡 Small steps in code today can lead to powerful solutions tomorrow.
