Excited to share my new blog post: "𝗘𝗿𝗿𝗼𝗿 𝗛𝗮𝗻𝗱𝗹𝗶𝗻𝗴 𝗶𝗻 𝗝𝗮𝘃𝗮𝗦𝗰𝗿𝗶𝗽𝘁: 𝗧𝗿𝘆, 𝗖𝗮𝘁𝗰𝗵, 𝗙𝗶𝗻𝗮𝗹𝗹𝘆" I’ve broken down the core concepts of robust error management in JavaScript — from the basics of try…catch blocks to the often-overlooked power of finally, with practical examples and real-world best practices. Whether you’re just starting out or sharpening your backend skills, this one is designed to help you write cleaner, more resilient code.

📅 Day 21/21 – React Hook Form & Validation (Final Day 🎯) ⚛️ On the final day of my challenge, I learned how to handle forms and validation efficiently using React Hook Form. 🔹 What is React Hook Form? It is a library that simplifies form handling in React with: ✔ Less code ✔ Better performance ✔ Built-in validation support 🔹 Why use it? Instead of managing multiple states manually: • It uses refs internally • Reduces unnecessary re-renders • Makes forms cleaner and scalable 🔹 Basic Example import { useForm } from "react-hook-form"; function App() { const { register, handleSubmit } = useForm(); const onSubmit = (data) => { console.log(data); }; return ( <form onSubmit={handleSubmit(onSubmit)}> <input {...register("name")} /> <button type="submit">Submit</button> </form> ); } 🔹 Validation Example <input {...register("email", { required: "Email is required" })} /> 💡 Final Takeaway from 21 Days Over the last 21 days, I learned: ✔ Core JavaScript concepts ✔ React fundamentals ✔ Real-world development thinking ✔ Consistency and discipline This journey helped me grow from learning concepts → building projects → understanding how things work internally. 🙏 Thanks to Devendra Dhote and Sheryians Coding School for the guidance throughout this journey. 🚀 This is not the end… just the beginning. #ReactJS #JavaScript #FrontendDeveloper #LearningInPublic #Consistency #WebDevelopment

Have you ever paused to think about how JavaScript’s asynchronous nature has completely transformed our lives as developers? From eliminating blocking code to enabling smooth, non-blocking user experiences — async programming is the reason modern web apps feel so fast and responsive today. In my latest blog, I break down the fundamentals of Synchronous and Asynchronous JavaScript. 🔗 Read the full post here: https://lnkd.in/egq38-vw Would love to hear from you in the comments 👇 Grateful to the incredible Chai Aur Code community that keeps pushing us forward every day!

Is Array.prototype.reduce() the final boss of JavaScript? For a long time, .reduce() felt like magic to me, the kind of magic that breaks your code if you look at it wrong. But after using it across everything from school projects to professional builds, I realized it’s all about how you visualize it. I just published a new Medium blog where I break down this "Swiss Army knife" of methods using my personal 3-level framework: 1. Understanding things like a 5-year-old 2. Understanding things like a Teenager 3. Understanding things like an Advanced Programmer. #JavaScript #WebDevelopment #CodingTips #SoftwareEngineering #MediumBlog #TechLearning

I just published a new article breaking down some of the most important React fundamentals that finally clicked for me. https://lnkd.in/df7igt6X It covers: - Declarative vs Imperative thinking - Components and Props - State and why it actually matters - The real reason React re-renders - Common mistakes with event handling One of the biggest takeaways for me was understanding this: React doesn’t “update variables” — it re-runs your component, and only state survives between renders. That small shift in thinking makes a huge difference when working with React. If you’re learning React or struggling with concepts like state and re-renders, this might help clarify things. I’d appreciate any feedback or thoughts. #React #JavaScript #Frontend #WebDevelopment #LearningInPublic

While writing some JavaScript logic recently, I noticed I was getting stuck on simple decision-making in code. Nothing complex just if-else and switch. But it made me realize I was writing conditions without really thinking through the flow properly. So I went back, broke it down, and tried to understand how control flow actually works. That led me to write this blog. If you’re learning JavaScript or revisiting the basics, this might help: https://lnkd.in/dNjZqNuS #JavaScript #LearningInPublic #WebDevelopment #BuildInPublic #chaicode #chaiaurcode

Day 1 of learning React Today marks the beginning of my journey into React, and I’m excited to share what I’ve learned so far. I started by understanding how to set up React using external libraries and how Babel plays an important role. Since browsers don’t understand JSX directly, Babel compiles it into regular JavaScript that the browser can execute. One thing I’ve realized already is that React makes building user interfaces more structured and scalable. Instead of writing plain JavaScript, we use JSX a syntax that looks like HTML but works inside JavaScript. Here are a few core concepts I explored today: • Components Components are like reusable building blocks for your UI. Instead of writing one large file, you break your interface into smaller, manageable pieces. Example: function Welcome() { return Hello, World!; } • Fragments Sometimes you want to return multiple elements without adding unnecessary divs to your HTML. That’s where fragments come in. Example: <> • Props Props (short for properties) allow you to pass data from one component to another, making your components dynamic. Example: function Welcome(props) { return Hello, {props.name}; } • Conditional Rendering (Guard Operator) In React, we can use the “&&” operator directly inside JSX to render something based on a condition. Example: {isLoggedIn && Welcome back!} This will only display the message if isLoggedIn is true. It hasn’t been easy stepping into something new, but I’m committed to learning and improving every day. #React #JavaScript #FrontendDevelopment #WebDevelopment #LearningInPublic #CodingJourney #100DaysOfCode #BuildInPublic

🧠 JavaScript Closures — The Concept That Feels Confusing (Until It Clicks) Closures are not magic… they’re just how JavaScript remembers things. 👉 Definition: A closure is when a function “remembers” variables from its outer scope even after that outer function has finished executing. 💻 Example: function outer() { let count = 0; return function inner() { count++; console.log(count); }; } const counter = outer(); counter(); // 1 counter(); // 2 counter(); // 3 🤯 Why this works? Even though "outer()" is done, the "inner()" function still has access to "count". That’s a closure. 🔥 Real Use Cases: ✔ Data privacy (like private variables) ✔ Creating counters ✔ Maintaining state in functions ✔ Used heavily in React (hooks concept) 💡 Simple Way to Remember: 👉 “A function + its remembered environment = Closure” I learned this concept from 👉 Sheryians Coding School #javascript #frontend #webdevelopment #coding #developers #100DaysOfCode
