🚀 Understanding the useState Hook in React.js React Hooks changed the way we build components—and useState is one of the most important ones to know. The useState hook allows functional components to manage state without using class components. It makes code cleaner, simpler, and easier to maintain. 🔹 Why use useState? Manage local component state Write less boilerplate code Improve readability and reusability Follow modern React best practices 🔹 Example:Sure!

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.

99% of React beginners make this mistake. I was one of them. 😬 ━━━━━━━━━━━━━━━━ ❌ WRONG const [arr, setArr] = useState([]); arr.push(1); setArr(arr); ✅ RIGHT setArr([...arr, 1]); ━━━━━━━━━━━━━━━━ Why? React doesn't look INSIDE your array. It just checks—is this the same object? You mutated it. Same object. React shrugs. No re-render. 🤷 Always give React something NEW. Spread it. Slice it. Map it. Just don't mutate it. #React #JavaScript #Frontend #LearnToCode #ReactJS

🚀 Project: URL Short Code Generator I was curious about how URL shortening services work, so I built a project to understand the core logic behind them. 🔹 This project focuses on the first step of a URL shortener: generating a short code that represents an entire long URL. 🔹 Users can: Enter a long URL Get a randomly generated short code 🔹 The project currently does not handle redirection — it intentionally focuses on short code generation, which is the foundation of any URL trimming service. 🛠 Tech Stack React Express.js Sowmya Nagarajan Uptor #WebDevelopment #FullStackDevelopment #JavaScript #ReactJS #ExpressJS #NodeJS #BackendDevelopment #FrontendDevelopment

DAY 16 OF POSTING REACT CONTENT ⚛️ React didn’t start with Hooks. Earlier, React components were written using classes. They worked, but understanding this, lifecycle methods, and structure took time. In 2018, React introduced Hooks. Hooks allowed developers to write components as simple functions, manage state without classes, and avoid this completely. Classes are still supported. But Hooks became the preferred way because they made React easier to read, write, and maintain. React didn’t remove classes — it just found a simpler way forward. #ReactJS #ReactBasics #JavaScript #FrontendDevelopment #LearnInPublic #WebDevelopment #CodingJourney

Here is something new for react developers... I kept seeing the same pattern: useState works, useEffect works, but the mental model is missing. So I built #HooksHub a simple place for developers who are learning React and want to understand hooks properly, not just memorize syntax. It’s still evolving, but the goal is clear: explain hooks the way developers actually think. Read here: https://lnkd.in/g683-9Wu Which hook gave you the most trouble at first? #ReactJS #ReactHooks #FrontendDevelopment #JavaScript #WebDevelopment #Developers #BuildInPublic #LearnReact

Clean React code isn’t about being clever. It’s about being clear. Readable code scales better than “smart” code. Predictable patterns outlive trendy abstractions. Simple logic is easier to debug, test, and maintain. As teams grow, clarity becomes a feature. If your teammates need extra time to understand your code, the system slows down too. Good React code answers questions before they’re asked: • Where does state live? • How does data flow? • What is this component responsible for? The goal isn’t to impress other developers. The goal is to make the system easy to reason about — even months later. #ReactJS #JavaScript #CleanCode #FrontendDevelopment #SoftwareEngineering #MaintainableCode #WebDevelopment #TechCareers

💡 Before React. Before Node. Before fancy frameworks. There is HTML, CSS, and JavaScript. And honestly? Most bugs I’ve seen in projects come from weak fundamentals — not advanced concepts. Here’s what strong basics actually mean: 🔹 HTML Understanding semantic tags, accessibility, proper structure. 🔹 CSS Knowing flexbox, positioning, box model, responsiveness — not just copying styles. 🔹 JavaScript Understanding closures, async/await, event loop, array methods — not just syntax. Frameworks change. Fundamentals don’t. The stronger your basics, the easier React, Node, or any tech becomes. Every time I improve my JS fundamentals, my React code improves automatically. #WebDevelopment #JavaScript #FrontendDeveloper #ReactJS #FullStackDeveloper #SheryiansCodingSchool

Day 16 I used to chase new frameworks every week. React today. Next.js tomorrow. React native next month. But here’s what I’m learning: The real edge is mastering the basics. ✔️ Clean HTML structure ✔️ Proper CSS layout (Flexbox & Grid) ✔️ JavaScript fundamentals ✔️ Understanding how APIs actually work Most developers don’t lack tools. They lack depth. The goal isn’t to know everything. The goal is to be so solid at the fundamentals that you can build anything. Today I revised core JavaScript concepts and focused on writing cleaner, simpler logic. No hype. Just reps. #FrontendDevelopment #JavaScript #WebDevelopment #BuildInPublic #SoftwareEngineering

🚀 All the JavaScript You Need Before React If you’re planning to learn React, don’t rush into it blindly. This video breaks down the exact JavaScript concepts you must understand before React — no fluff, only what React uses daily 👇 ✔️ Destructuring ✔️ Immutability & spread operator ✔️ Array methods (map, filter, reduce) ✔️ Conditional rendering (ternary & &&) ✔️ Optional chaining ✔️ ES modules ✔️ Async JavaScript & Promises 📊 Over 81K+ views already — clearly helping a lot of devs get their fundamentals right. If React ever felt confusing, chances are JavaScript fundamentals were the missing piece. 🎥 Find the video link in the comments 👇 💡 Save this for later or share it with someone starting React. 👉 Follow me for more practical JavaScript, React, and MERN content — I’ll be posting consistently. #JavaScript #ReactJS #WebDevelopment #Frontend #MERN #Programming #LearnToCode
