Exploring React Hooks and Virtual DOM with Akshay Saini

🚀 Mastering useEffect in React If you’ve ever wondered why your component keeps re-rendering, or how to handle side effects properly, useEffect is your best friend (when used right!). 🧠 What is useEffect? useEffect lets you perform side effects in functional components — like fetching data, updating the DOM, or setting up event listeners. 💡 Basic Syntax useEffect(() => { // Side effect logic here return () => { // Cleanup (optional) }; }, [dependencies]); ⚙️ Dependency Array Explained [] → runs only once (on mount) [variable] → runs when variable changes (no array) → runs after every render 🧩 Common Use Cases ✅ Fetching data from an API ✅ Subscribing / unsubscribing to events ✅ Managing timers or intervals ✅ Syncing state with localStorage ⚠️ Avoid These Mistakes ❌ Forgetting the dependency array ❌ Updating state inside useEffect without proper dependencies (infinite loop alert 🚨) ❌ Not cleaning up event listeners or intervals 🌱 Pro Tip Always think of useEffect as a lifecycle tool — it replaces componentDidMount, componentDidUpdate, and componentWillUnmount from class components. #ReactJS #FrontendDevelopment #WebDevelopment #JavaScript #ReactHooks #useEffect

Ever felt tired of passing props through multiple components just to share the same data? 😩 That’s where React Context API comes in! ⚛️ It allows you to share data across components — like theme, language, or user info — without prop drilling. In short 👇 🧩 Prop Drilling → pass data manually through each level 🌐 Context API → create a central Provider that shares data directly with any component ⚙️ No need to repeat props again and again! This diagram shows how Context API helps React apps stay cleaner and easier to maintain. Have you used Context API in your projects yet? Let me know how it helped your workflow 👇 #ReactJS #Frontend #WebDevelopment #JavaScript #ReactDeveloper #Coding #ContextAPI

Github: https://lnkd.in/gXq_-4mp 🔥 Project 2/20 — Sticky Header + Scroll Reveal ✨ Today we’re leveling up UI fundamentals. No React, no Tailwind — just pure HTML, CSS & JavaScript flexing its muscles. This sticky navbar transforms as you scroll, paired with silky smooth reveal animations using the Intersection Observer API. Modern devs love frameworks. Great devs master fundamentals first. And we’re building the foundation brick by brick — one clean UI at a time. Because good code isn’t just written — it’s crafted. 📌 Concepts: ✅ Scroll events ✅ Intersection Observer ✅ DOM manipulation ✅ UI animations 🔗 GitHub repo in bio Follow along — 18 more fire projects coming.

Don't let your React project turn into a mess! A clean folder structure is the key to scalable and maintainable code. I'm sharing my preferred project layout that separates concerns and makes finding code much simpler: -> pages (URL-based views) -> components (Reusable Ul elements) -> hooks (Reusable logic) -> contexts (State sharing) -> layouts (Dynamic containers like Navbars/Sidebars) Check out the slides for a full breakdown!

Learning React can feel overwhelming with all the new terms, patterns, and frameworks floating around. That's why I appreciated stumbling upon this comprehensive React handbook that cuts through the noise. What I found most valuable is how it focuses purely on React's core concepts—no unnecessary frameworks or distractions. Once you grasp these fundamentals, you gain the confidence to build anything from small components to full-stack applications. The guide breaks down complex topics like JSX, hooks, and rendering into digestible sections with practical examples. I particularly liked the clear explanations of state vs refs vs variables—a common point of confusion for many developers. As someone who works with React regularly, I still found some useful reminders about best practices like: - Using stable IDs for keys when rendering lists - Understanding React's component lifecycle (trigger → render → commit → paint) - Choosing the right styling approach for your project Whether you're just starting with React or looking to strengthen your fundamentals, this handbook provides a solid foundation. It's one of those resources that makes you think, "Why didn't I understand this concept this way before?" #React #JavaScript #WebDevelopment #Frontend #Programming #Developer

JavaScript Promise.race() — When Speed Matters! Sometimes, you don’t need all async tasks to finish — you just want the fastest one’s result That’s where Promise.race() comes in! 💡 Definition: Promise.race() takes an array of promises and returns the result of the first one that settles (either resolved or rejected). 🧩 Example: const fast = new Promise((resolve) => setTimeout(() => resolve("🚀 Fast task completed!"), 1000) ); const slow = new Promise((resolve) => setTimeout(() => resolve("🐢 Slow task completed!"), 3000) ); Promise.race([fast, slow]) .then((result) => console.log("Winner:", result)) .catch((error) => console.error("Error:", error)); ✅ Output: Winner: 🚀 Fast task completed! Even though the slow promise finishes later, the first one decides the result. Why Use It? ✅ Get quick responses from multiple sources ✅ Useful in timeout or failover situations ✅ Improves user experience by reacting faster 🔖 #JavaScript #PromiseRace #AsyncProgramming #WebDevelopment #Frontend #JSConcepts #CodingTips #100DaysOfCode #KishoreLearnsJS #WebDevCommunity #DeveloperJourney #AsyncAwait

🚀 BIG NEWS: My CLI Project is LIVE on npm! 🚀 After countless hours of coding, caffeine, and creativity, I’m thrilled to announce the launch of vite-pro-cli — an ultra-fast CLI tool that creates a fully configured Vite + Tailwind CSS project in seconds. No setup, no prompts, just instant productivity! ✨ What makes vite-pro-cli special? Zero configuration — run one command and you’re ready to code. Pre-configured Vite + TailwindCSS (with TypeScript or JavaScript support). Instantly starts your dev server — build faster, ship sooner. Cleans up clutter (goodbye, unused folders). Beautiful UI out of the box, with gradients and smooth animations. 🚧 Why build this? Every minute spent setting up a project is a minute lost on innovation. This tool removes all that friction for you, letting developers focus on what they do best: building. 🤝 Try it out! Install globally with: - npm install -g vite-pro-cli ...then start your next project instantly: - vite-pro-cli my-app 🔗 Check it out: https://lnkd.in/d25W_t6w #webdevelopment #javascript #reactjs #tailwindcss #opensource #vite #npm

Day 10 of React30 🧱 Class Components - The OG React Heroes 🧩 Before hooks were introduced, Class Components ruled React! 👑 They were used to handle state, lifecycle methods, and complex logic inside components. ⚙️ What Are Class Components? Class Components are ES6 classes that extend React.Component. They can hold state and respond to lifecycle events like mounting, updating, and unmounting. Example: class Welcome extends React.Component { render() { return <h2>Hello, {this.props.name}! 👋</h2>; } } Usage: <Welcome name="Aman" /> 🧠 Why They Were Used ✅ To manage state (before hooks existed) ✅ To use lifecycle methods like componentDidMount, componentDidUpdate ✅ To separate UI logic and state logic 🚀 Why They’re Less Common Now 💠Hooks (introduced in React 16.8) brought the same power with less boilerplate. Now, most developers use Functional Components + Hooks instead of Classes. 💡 Key Takeaway Class Components were essential in React’s evolution they walked so Functional Components could run 🏃♂️💨 #ReactJS #React30 #FrontendDevelopment #WebDev #JavaScript #ReactComponents #LearnReact
