Prevent Race Conditions with AbortController in React

🚀 React Series - Day 9 Handling Forms in React (Controlled + Modern Approach) Forms are a core part of almost every application - login pages, registrations, search, and more. In React, forms are typically handled using a controlled approach. This means: • Form data is stored in state • Inputs are controlled by that state • Changes are handled using events like onChange This gives full control over user input and makes validation easier. However, as forms grow more complex, managing state manually can become repetitive and harder to scale. That’s why many developers use modern solutions like React Hook Form. It provides: • Better performance (fewer re-renders) • Easy validation • Cleaner and less repetitive code 👉 The idea is simple: Start with controlled components to understand the basics, then use tools like React Hook Form to handle real-world, complex forms efficiently. #reactjs #javascript #frontenddeveloper #webdevelopment #codinginterview #learnreact #30daysofcode #programming #reactinterview #react #coding

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

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.

⚛️ Common React Mistakes That Are Killing Your Performance 💀 You think your React code is fine… . But these small mistakes are silently breaking your app 👀 Here’s what most developers still do wrong 👇 . ❌ Mutating state directly React won’t re-render properly (page 2)  ❌ Using index as key Leads to weird UI bugs when list updates (page 3)  ❌ Too much global state Unnecessary re-renders & messy logic (page 4)  ❌ useEffect misuse Missing dependency array = infinite loop 🔁 (page 5)  ❌ Storing derived state You’re duplicating logic for no reason (page 6)  ❌ Too many re-renders New objects/functions every render = performance drop (page 7)  ❌ Ignoring loading & error states Your UI breaks when API fails (page 8)  ❌ Poor folder structure Good code needs good organization (page 9)  . 🔥 React isn’t hard… Bad practices make it hard 💬 Clean code = scalable apps 📌 Save this before your next project .

React taught me more than building interfaces… it transformed the way I thought as a programmer. Previously, I programmed solely to “get stuff done.” However, while developing in React, I found myself thinking in terms of: 🧩 Decomposing complicated tasks into simple, modularized components 🔁 State management instead of direct DOM manipulation ⚡ Coding in a deterministic and scalable manner What I learned: Excellent React programming isn’t about applying additional hooks… it’s about implementing proper logic at the right places. From now on, before programming anything, I question: Is this component reusuable? Does this piece require state management? Can I simplify it further? This change in approach improved my coding style. Learning never stops. Improvement never ends. 🚀 #ReactJS #FrontEndDevelopment #JavaScript #CleanCoding #MERNStack #ProgrammerLife

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

🐛 A small bug wasted 3 hours of my time. I was building a React project. Everything looked correct. The API was working. The component was rendering. There were no errors in the console. But the UI was still not updating. For 3 hours, I kept checking the wrong things. Then I finally noticed the problem. I was directly mutating the state instead of creating a new one. Something as small as this: ❌ state.push(newItem) ✅ setState([...state, newItem]) And suddenly, everything started working. That moment reminded me of something important: In development, the biggest problems are often caused by the smallest mistakes. Since then, whenever something doesn’t work, I try to remember: • Don’t panic • Check the basics first • Read the code slowly • Small details matter Because debugging is not just about fixing bugs. It’s about learning how to think better. 💬 What is one bug that taught you an important lesson? #ReactJS #JavaScript #debugging #webdevelopment #developers #learning #softwareengineering

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

⚠️ JavaScript Arrays: Mutating vs Non-Mutating Quick thing that caused me way too many bugs before I really paid attention to it 👇 Some array methods actually change the original array… and some don’t. 🧠 Mutating → they modify the same array ✨ Non-mutating → they give you a new one instead Sounds simple, but here’s where it gets tricky… I used to assume my original data was “safe”, then suddenly something else in the app behaved weirdly — turns out I had already changed that array without realizing it. The tricky part is that mutations aren’t always obvious at first. You might only notice later when something behaves differently than expected. This becomes even more important when working with state (like in React), where consistency really matters. Not a big concept… but it makes a big difference. #JavaScript #WebDev #FrontendDevelopment #ReactJS #CodingTips #ProgrammingTips
