How React Works Behind the Scenes After learning JSX, I wanted to understand what actually happens when a React app runs. Here’s what I discovered: 1) The browser first loads index.html, which contains a root div. 2) React connects to that root element using main.jsx. 3) The main component (App) is executed and returns JSX. 4) JSX is converted into regular JavaScript (React elements). 5) React creates a Virtual DOM — a lightweight copy of the real DOM. 6)When changes happen (like state updates), React: Creates a new Virtual DOM Compares it with the previous one Updates only the changed parts in the real DOM This process makes React efficient and fast. Understanding what happens behind the scenes makes writing React code much more meaningful.

While building React projects, I realized that form handling is one of the most important concepts to master. Almost every application needs forms — login, signup, feedback, search. Here are 4 ways I learned to handle forms in React: 1️⃣ Controlled Components → Using useState to manage input values 2️⃣ Uncontrolled Components → Using useRef to access input directly 3️⃣ Single State Object → Managing multiple inputs with one state 4️⃣ Form Libraries → Using React Hook Form / Formik for scalability The biggest learning for me: 👉 Controlled components give more control 👉 Libraries save time in large applications Still exploring and building more projects 🚀 #ReactJS #WebDevelopment #JavaScript #FrontendDevelopment #CodingJourney

React Hands-on Series #5 📝 Problem Statement: Build a Form using react-hook-form Forms are everywhere. But building them the right way separates beginners from professionals. This time — no basic useState form handling. Let’s use react-hook-form ⚡ Your Task: Create a form with: ✅ Name field ✅ Email field...etc ✅ Proper validations ✅ Error messages ✅ Submit handler 🛠 Concepts You’ll Practice: 👉useForm 👉register 👉formState 👉Validation rules 👉Performance-optimized forms 🧠 Why react-hook-form? 🔥Less re-rendering 🔥Better performance 🔥Cleaner validation logic 🔥Used in real production apps If you can build forms cleanly using this library, You’re leveling up fast 🚀 #React #ReactHookForm #FrontendDevelopment #JavaScript #WebDevelopment #BuildInPublic #CodingChallenge

Everyone wants to learn the latest framework. But here’s the truth: Frameworks change. Fundamentals don’t. You can learn React in weeks. You can build apps with Next.js quickly. But if you don’t deeply understand JavaScript: Closures Event loop Async behavior Prototypes Execution context You’ll struggle when the app scales. Modern frontend is not about “making it work.” It’s about: • Why did this re-render happen? • Why is this component slow? • Why is memory increasing? • Why is hydration failing? Those answers don’t come from React. They come from JavaScript. AI can generate components. But it cannot debug your mental model. That’s why I’m focusing on strengthening core JavaScript while building real-world projects. Because strong foundations make you framework-independent. And framework-independent developers survive every market shift. #JavaScript #FrontendDevelopment #ReactJS #NextJS #WebDevelopment #LearningInPublic

Just built an Image Search App using HTML, CSS, and JavaScript! This beginner-level project helped me understand: • API fetching • Async/await • DOM manipulation • Real-time search functionality • Handling user input dynamically Instead of only watching tutorials, I’m focusing on building projects to strengthen my logic and problem-solving skills. 🔗 Live Demo: https://lnkd.in/dJFqjFzg Small steps every day towards becoming a better developer 💻✨ #JavaScript #WebDevelopment #FrontendDeveloper #LearningByBuilding #100DaysOfCode

⚛️ I used to think form handling in React was complicated… until I built a CRUD system with React Hook Form. 🚀 Day 18 of My Web Development Journey Today I took my understanding further by building a User Management System (CRUD) using React Hook Form. 💻 What I explored: • Generating unique IDs using nanoid • Real-time validation with mode: "onChange" • Tracking form validity using isValid • Managing inputs with defaultValues • Implementing full CRUD operations The biggest realization? 👉 Form handling becomes much simpler and cleaner when you use the right tools. Building small projects like this is helping me connect concepts with real-world use cases. What’s your preferred way of handling forms in React? 🤔 Devendra Dhote bhaiya is the best on teaching react #ReactJS #ReactHookForm #WebDevelopment #JavaScript #CRUD #BuildInPublic #LearningInPublic #FrontendDevelopment

𝗣𝗥𝗢 𝗧𝗜𝗣 𝗙𝗢𝗥 𝗦𝗛𝗔𝗥𝗘𝗗 𝗦𝗧𝗔𝗧𝗘 𝗜𝗡 𝗥𝗘𝗔𝗖𝗧 𝗡𝗔𝗧𝗜𝗩𝗘 When I was working on a project in React Native, I noticed that updating one input can re-render the entire form, making typing feel slow. Here’s how beginners can fix it in 3 simple steps: 1. Use local state Assign each input its own local state instead of storing everything in a single parent state. 2. Wrap components with React.memo This prevents components from re-rendering unless their props actually change. 3. Use useCallback for handlers Pass stable functions to components so they don’t re-render unnecessarily. 𝗥𝗲𝘀𝘂𝗹𝘁: ➡Typing stays smooth even with 50+ inputs ➡The app feels instant and responsive ➡Users don’t notice the complexity behind the scenes React Native is fast — your state management makes all the difference.

From time to time, I publish blog posts. First, because I enjoy writing and sharing what I learn. But also because I know that one day, when I need to revisit a topic… I’ll be glad to have everything documented in one place! Today, I found myself using SweetAlert2 again in a Shiny application. SweetAlert2 is a JavaScript library that makes it easy to create beautiful modals, far less austere than the default ones in Shiny! Thanks to a blog post I had written some time ago, I was able to quickly recall the key requirements for integrating a JavaScript library into a Shiny app. If you’re looking to give your apps a fresh new look, feel free to check it out 🙂 https://lnkd.in/dYpR4hsr #RStats #Shiny #JavaScript
