Node.js Promises: Handling Asynchronous Operations

One common issue in async JavaScript is repetitive try/catch blocks that make code messy and harder to maintain. A cleaner approach is the await-to pattern, which wraps promises and returns [error, data]. This keeps your async functions clean, readable, and easier to debug. ✅ No nested try/catch ✅ No swallowed errors ✅ Cleaner and reusable code ✅ Better error handling pattern Sometimes the best optimization is not adding more code — it’s removing repetition.

After writing JavaScript for years, switching to TypeScript was a huge productivity boost. Example problem in JavaScript: function calculateTotal(price, quantity) { return price * quantity } What if someone passes a string? calculateTotal("10", 5) This may silently create bugs. TypeScript solves this: function calculateTotal(price: number, quantity: number): number { return price * quantity } Now the compiler protects your code before it reaches production. This is why most modern projects use: • React + TypeScript • Node.js + TypeScript • Next.js + TypeScript Type safety = fewer production bugs.

Many beginners think querySelector() in JavaScript and useRef() in React do the same thing. But React uses a Virtual DOM, so direct DOM manipulation can break React’s flow. That’s why useRef() gives controlled access to the DOM while keeping React’s architecture intact.

3 questions I ask before writing any function: 1. Can someone understand this in 30 seconds? 2. Am I solving a real problem or a hypothetical one? 3. Is there a simpler way to do the exact same thing? That's KISS in practice. It sounds obvious. But most of us (myself included) have violated all three in the same pull request. Wrote a full breakdown of the KISS Principle — with actual Node.js/Express/Prisma examples showing what over-engineered vs clean code looks like in real backend work. No theory fluff. Just code, context, and the mental shift that actually sticks.

Today Class was on Internals of Node.js! Understood how Node.js runs on a single main thread, uses the event loop to handle async tasks, and a thread pool (default 4 threads) for heavy operations. Also learned how phases like I/O polling, expired callbacks, and setImmediate work behind the scenes. Really interesting to see how Node.js executes code internally. #NodeJS #NodeJSInternals #JavaScript #EventLoop #ChaiCohort26 #Chaicode Hitesh Choudhary Chai Code #piyushgarg Anirudh Jwala Akash Kadlag Jay Kadlag JavaScript

Most devs add TypeScript to React by putting types on everything. Expert TypeScript has fewer annotations, not more. The real power isn't string and number on your props. It's discriminated unions that make impossible states unrepresentable, generic components that scale without duplication, and a useRef overload that most people have never seen explained properly. Here are 5 patterns that will change how you write TypeScript in React - from the basics most people get wrong to the advanced patterns that separate senior from mid-level code.

Day 9 – Node.js Using fs.promises Node.js provides a Promise-based version of the fs module that works seamlessly with async/await. Instead of callback-based APIs, we can use: require('fs').promises This improves readability, structure, and production-level code quality.

⚡ Most developers accidentally make async JavaScript slower than it needs to be. A lot of people write async code like this: await first request wait… await second request wait… await third request It works. But if those requests are independent, you’re wasting time. The better approach: ✅ run them in parallel with Promise.all() That small change can make your code feel much faster without changing the feature at all. Simple rule: If task B depends on task A → use sequential await If tasks are independent → use Promise.all() This is one of those JavaScript habits that instantly makes you look more senior 👀 Join 3,000+ developers on my Substack: 👉 https://lnkd.in/dTdunXEJ How often do you see this mistake in real codebases? #JavaScript #WebDevelopment #Frontend #SoftwareEngineering #AsyncJavaScript #Promises #CodingTips #Developers #LearnToCode #AITechDaily

Why You Should Learn TypeScript — Even If You Know JavaScript 🚀 “I already know JavaScript… why do I need TypeScript?” That’s exactly what I thought too. But once you start building larger applications, you realize: 👉 Bugs increase 👉 Code becomes harder to maintain 👉 Team collaboration becomes messy 👉 Refactoring becomes risky That’s where TypeScript changes the game. It’s not about replacing JavaScript. It’s about writing safer, scalable, and professional code.
