⚛️ A quick React learning story from my coding journey! While working on a small React project, I ran into a weird error when using the useState hook. I had declared it outside the component function — and React wasn’t happy about it! 😅 Here’s what I learned: ❌ Wrong way: const [count, setCount] = useState(0); // ❌ Outside the component function Counter() { return <button>{count}</button>; } ✅ Correct way: function Counter() { const [count, setCount] = useState(0); // ✅ Inside the component return <button onClick={() => setCount(count + 1)}>Count: {count}</button>; } 💡 Lesson learned: useState (and all React hooks) must be called inside the component function — not outside or inside loops or conditions. React uses the order of hooks to track state, and breaking that rule confuses it. It was a small mistake, but understanding why it happens really helped me grasp how hooks work behind the scenes. Every bug is just React teaching you something new. 💪✨ #ReactJS #JavaScript #MERNStack #FrontendDevelopment #WebDevelopment #LearningByDoing #CodingJourney

🚀 Learning React has made me a better problem solver, if not a better developer. When I run into bugs today, most of them are not “react problems” so much as they are thinking problems. Here are a few habits that changed everything for me: Break big problems into little steps Read the error message slowly, because 90% of the time the answer is in the error message 😅 Reuse logic in custom hooks rather than rewriting code Don’t try to fight react, flow with the data Every time I work through a tricky bug, I feel like I have leveled up again. That’s the fun part about being a developer. 💙 #ReactJS #WebDevelopment #FrontendDevelopment #Programming #ProblemSolving #DeveloperLife

I thought teaching React for 7 days would make me better at React. Instead… it made me better at thinking. 🧠 When I started the 7 Days of React series, I wanted to teach concepts — not just code. But halfway through, I realized something deeper: Explaining React was actually debugging how I think about it. 💡 Here’s what the journey taught me 👇 🧩 1️⃣ Teaching forces clarity If you can’t simplify it, you don’t really understand it. Explaining React forced me to slow down — and see what I was skipping. ⚙️ 2️⃣ Simplicity is harder than complexity Anyone can add hooks. But removing unnecessary ones — that’s art. 💬 3️⃣ Content creation = code review for your brain Every post made me catch a mental bug in how I explain things. 🧠 4️⃣ Teaching builds humility There’s always someone who knows more. But growth starts when you start sharing anyway. By the end of the series, I didn’t just improve my React skills. I improved how I learn, write, and teach. If you ever feel stuck in tutorials — explain what you already know. You’ll grow faster than any course could teach you. 🚀 ❤️ If this hit home, 🔖 Save it for your next self-doubt day, 👥 Follow https://lnkd.in/dhSg-nTK — “5 Days of Clean Code” starts soon. #ReactJS #JavaScript #Frontend #WebDev #CodingMindset #DeveloperJourney #LearningInPublic

💭 Nobody talks about this part of learning to code. It’s not the syntax. It’s not the bugs. It’s the patience it takes to stay consistent when you feel like you’re not improving. You watch tutorials. You build small projects. You compare yourself to others who seem way ahead. But what you don’t see is that every single developer has been there. Progress isn’t always visible. Some days you debug for hours. Some days you build something that finally clicks and that’s growth. 💡 If you’re learning React, Flutter, or JavaScript right now remember: it’s not a sprint; it’s a skill that compounds. Keep building. Keep showing up. The results come quietly. ⚙️ 👉 What’s one thing you wish you knew earlier in your coding journey? #CodingJourney #Frontend #WebDevelopment #Motivation #ReactJS #Flutter

🚀 Asynchronous Programming with Callbacks (JavaScript) Node.js heavily relies on asynchronous programming to handle I/O operations without blocking the main thread. Callbacks are a common way to handle the results of asynchronous operations. A callback function is passed as an argument to an asynchronous function and is executed when the operation completes. While effective, deeply nested callbacks can lead to "callback hell," which is difficult to read and maintain. 🎓 Learning never exhausts the mind — it energizes it! 🚀 Your learning hub — 10k concepts, 4k articles, 12k quizzes.

🌟 React.js - The Skill That keeps Giving 🌟 When I first started learning React, I thought it was just another javascript library. but slowly I realized something.... 🤔 React is not only about components, state or useEffect. it teches you how to think in a structured way. 🤔 Break things into small pieces. 🤔 Reuse what works. 🤔 Manage complexity one step at a time. And honestly that mindset helps beyond coding too. Whether you're building a small form or a full product... React reminds you: ✅ Start simple ✅ Keep things modular ✅ Improve as you go If you are learning React today 👉 keep going. If you are already building with it 👉 you know the magic. And if you are stuck 👉 we have all been there. Just debug, hydrate and keep clicking refresh 😀 Happy coding 🧑💻⚛️ ⚡Abhishek Patel #react #javascript #coding #sde

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

🎯 Today’s Lesson: Why You Should Learn the Language Before the Framework 💻 A lot of beginners jump straight into React, Angular, or Flutter before understanding the core language — and that’s one of the biggest mistakes you can make 😅 💡 A framework is just a tool built on top of a language. It gives you structure and shortcuts to build faster… but it doesn’t teach you what’s really happening behind the scenes. 🔍 Simple example: If you learn React before JavaScript, you’ll know how to use components — but when a bug appears, you’ll have no idea where it came from. ⚙️ Why learn the language first? 🔹 Frameworks change — languages stay. Today it’s React, tomorrow Svelte, and next year something new. But JavaScript will still be the foundation. 🔹 Debugging requires language knowledge. The framework won’t fix your errors — you need to understand what your code is actually doing. 🔹 Frameworks hide complexity. They make coding easier, but they also hide how things really work. To become a strong developer, you have to understand what’s “under the hood.” 🔧 🔹 Master the language = master any framework. Once you know the logic and patterns, switching between React, Vue, or Angular becomes simple 🔄 📘 Golden rule: “Learn the roots before the branches.” 🌱 The language is the foundation — the framework is just its extension. ✅ In short: Before you dive into any tool, understand the mindset of the language itself. That way, when you start building with a framework, you’re not just memorizing syntax — you’re coding with understanding. #Programming #JavaScript #Frameworks #Developers #CodingTips #WebDevelopment #CleanCode #React #TunisiaTech #ANT_Tunisie
