Introducing Bun: A Fast JavaScript Toolkit

Today, I learned how Node.js works behind the scenes. First, I revisited JavaScript basics. JavaScript is a single-threaded, synchronous language, which means it executes code line by line. To understand the difference between synchronous and asynchronous execution, consider a restaurant example: Synchronous execution: - Coke: 0 min - Pizza: 10 min - Noodles: 5 min If five people order in sequence: 1. Person A orders Coke → ready in 0 min 2. Person B orders Pizza → ready in 10 min 3. Person C orders Noodles → ready in 15 min 4. Person D orders Noodles → ready in 20 min 5. Person E orders Pizza → ready in 30 min The orders are completed one after another, in the order they were received: A, B, C, D, E. This is synchronous execution — tasks are executed immediately and sequentially. Asynchronous execution: - Coke: 0 min - Pizza: 10 min - Noodles: 5 min If five people order at the same time: 1. Person A orders Coke → ready in 0 min 2. Person B orders Pizza → ready in 10 min 3. Person C orders Noodles → ready in 5 min 4. Person D orders Noodles → ready in 5 min 5. Person E orders Pizza → ready in 10 min Here, orders are completed as soon as they are ready, not necessarily in the order they were placed: - First, Coke is ready → Person A - Then Noodles → Person C and Person D - Finally Pizza → Person B and Person E This is asynchronous execution — tasks that take longer are offloaded, and shorter tasks finish first, allowing multiple tasks to run without blocking the main thread. In Node.js, the V8 engine (which executes JavaScript) delegates time-consuming tasks like file access, network calls, or database queries to libuv. Libuv is a low-level library written in C. It acts as a bridge between Node.js and the operating system, handling asynchronous tasks and returning the results back to the V8 engine. This is why Node.js is known for asynchronous I/O or non-blocking I/O — it can handle multiple tasks at the same time without blocking the main thread. Understanding this helped me see why Node.js is so powerful for building fast, scalable applications. #Nodejs #JavaScript #Async #BackendDevelopment #LearningJourney #WebDevelopment

This article provides a comprehensive introduction to React, covering essential concepts like JSX, hooks, and rendering. I found it interesting that the author emphasizes the flexibility React offers for both small components and large applications, making it a powerful choice for developers. What aspects of React do you find most beneficial in your projects?

Mastering Custom Hooks in React: A Developer's Guide React hooks revolutionized how we write components. But the true power of this system unfolds when you move beyond the built-in hooks and start creating your own. Custom hooks are the most important pattern for sharing stateful logic between components, and mastering them is a key step in becoming a proficient React developer. This guide covers how to build them, when they are necessary, and—just as importantly—when to avoid them, with advanced tips integrated throughout. A custom hook is simply a JavaScript function whose name starts with use and that calls other hooks. That's it. It's a convention that allows you to extract component logic into a reusable function. Let's start by identifying a piece of logic we might want to reuse. A common scenario is managing a boolean toggle state. Before (In a Component): function MyComponent() { const [isOpen, setIsOpen] = useState(false); const toggle = () => setIsOpen(!isOpen); return ( <div> <button onClick={toggle}>{isOpen https://lnkd.in/dVjM6Yvj

🧩 𝗙𝗿𝗼𝗺 𝗩𝗮𝗻𝗶𝗹𝗹𝗮 𝗝𝗮𝘃𝗮𝗦𝗰𝗿𝗶𝗽𝘁 𝘁𝗼 𝗥𝗲𝗮𝗰𝘁: 𝗠𝘆 𝗧𝘂𝗿𝗻𝗶𝗻𝗴 𝗣𝗼𝗶𝗻𝘁 𝗮𝘀 𝗮 𝗗𝗲𝘃𝗲𝗹𝗼𝗽𝗲𝗿 When I started learning JavaScript, I never realized how much I was already building framework-like systems, modular codebases with PubSub architecture, reusable components, and Webpack bundling. Now that I’m approaching the React section of The Odin Project, everything is starting to make sense. It feels like the path I’ve been walking was already leading here. React doesn’t feel foreign, it feels like a familiar idea, but with a cleaner, smarter structure. Here’s how I understand it so far 👇 𝗟𝗶𝗯𝗿𝗮𝗿𝘆: My imported/exported JavaScript components, I decide when and where to use them. 𝗙𝗿𝗮𝗺𝗲𝘄𝗼𝗿𝗸: A system that runs my code for me (it calls my callbacks). 𝗥𝗲𝗮𝗰𝘁: A JavaScript library that gives framework-like structure, but still lets me stay in control. So, React isn’t magic. It’s just ES6+ JavaScript in disguise, automating what I used to handle manually, like DOM updates and state management. And realizing that has made everything, from frameworks and libraries to backend logic, click in a deeper way. 📈 Above picture is my GitHub growth so far. Each commit represents a new discovery, from raw JS logic to component-based architecture, and now, stepping into React feels like the next natural chapter. #JavaScript #React #WebDevelopment #TheOdinProject #Frontend #LearningInPublic #GitHubJourney

⚔️ Node.js vs Deno — The Modern JavaScript Runtime Battle JavaScript runtimes have come a long way. For years, Node.js ruled the backend world. Then came Deno, built by the same creator of Node, but redesigned for the modern era. Here’s how they stack up 👇 🔵 Node.js Mature ecosystem + millions of packages Wide community and industry adoption Uses npm for package management Requires external tools like dotenv, nodemon (although newer Node versions now include built-in watch & env support) Flexible, but not secure by default Great fit for large-scale, production-ready systems 🟠 Deno Secure by default (no file/network access unless allowed) Built-in TypeScript support Uses URLs for imports instead of package.json Ships with built-in tools: formatter, linter, test runner, bundler Simpler, modern developer experience Still growing compared to Node’s ecosystem 🧠 My take? Node.js is battle-tested and perfect for production at scale. Deno is cleaner, modern, secure, and developer-friendly — great for new-age apps. Both are powerful. Choosing one depends on ecosystem needs vs. modern simplicity. Which one do you prefer right now? 👇😄 #NodeJS #Deno #JavaScript #TypeScript #WebDevelopment #Backend #FullStack

Lately, I’ve been working a lot with React, and one thing keeps standing out — it’s not really about React alone. It’s about how well you understand JavaScript. React just brings your logic to life on screen. But if your JavaScript isn’t solid — your state, functions, or data flow — things can get messy fast. I’ve realized that writing better React code often starts with going back to the basics: understanding how JavaScript handles data, functions, and re-renders behind the scenes. Sometimes, improving as a developer isn’t about learning a new framework — it’s about understanding the one you already use a little better. #React #JavaScript #Frontend #WebDevelopment #LearningEveryday

⚛️ React Hooks: A Game Changer in Functional Components React Hooks revolutionized how we write components — making code cleaner, more reusable, and easier to understand. 🔧 Before Hooks, managing state and lifecycle logic meant using class components. It worked, but let’s be honest — things got messy fast. Then came Hooks in React 16.8. Now we can: ✅ Manage state with useState ✅ Handle side effects with useEffect ✅ Share logic between components via custom hooks ✅ Tap into context, refs, reducers, and more — all in functional components Why does this matter? ➡️ Less boilerplate ➡️ Better separation of concerns ➡️ Easier testing and reuse ➡️ Improved developer experience 🔁 Hooks didn’t just simplify React — they made it more powerful. 💬 Are you using Hooks in production?

🧠 React + TypeScript: 6 Best Practices You Should Follow in 2025 TypeScript isn’t just a “nice-to-have” — it’s your safety net ⚡ Here’s how to make the most of it with React 👇 1️⃣ Type your Props and State properly Don’t leave things as any. Use interfaces or type aliases for clarity: interface UserProps { name: string; age?: number; } 2️⃣ Leverage React.FC wisely Use it only when you need children — otherwise, define function components normally. 3️⃣ Use Enums or Union Types instead of Strings They help avoid typos and make your code self-documented: type Status = "loading" | "success" | "error"; 4️⃣ Infer types from data when possible Don’t over-type — let TypeScript do the work. Example: const user = useState({ name: "", age: 0 }); // TypeScript infers type automatically 5️⃣ Always type your custom hooks When you return complex data, define what’s coming back. It makes your hooks reusable and predictable. 6️⃣ Enable strict mode in tsconfig.json Yeah, it complains a lot… but it catches bugs before your users do. 🚀 Clean + Typed + Organized = Frontend Peace of Mind. 💬 What’s one TypeScript habit that changed the way you code in React? #React #TypeScript #Frontend #WebDevelopment #CleanCode #BestPractices #JavaScript
