🚀 Output Challenge #6 — The useEffect Dependency Trap This one breaks most React apps silently 👇 function App() { const [count, setCount] = React.useState(0); React.useEffect(() => { console.log("Effect runs"); }, [count]); const handleClick = () => { setCount(count + 1); setCount(count + 1); }; return ( <div> <button onClick={handleClick}>Increment</button> </div> ); } 🧠 Question: You click the “Increment” button once. How many times does "Effect runs" appear in the console? And why? (Hint: Think about batched updates, dependencies, and state snapshots) 💬 Drop your answer + reasoning below 👇Let’s see who can explain what really happens behind React’s batched state magic 🔥 #React #Nextjs #JavaScript #Frontend #TypeScript #WebDevelopment #useEffect #Hooks #CleanCode #Performance #DeveloperCommunity #InterviewPreparation

Node.js just made dotenv and nodemon obsolete. For years, every project started with: npm i dotenv nodemon Not anymore. Now Node has: Native .env support → node --env-file=.env app.js Built-in watch mode → node --watch app.js No extra packages. No setup. Just pure Node. dotenv and nodemon walked so Node could run. #NodeJS #JavaScript #WebDevelopment #Backend #Developers #Coding #SoftwareEngineering #DevCommunity

Upgrade your Next.js app with this powerful new feature 🔥 👇 🚀 Next.js 16 — Explicit Caching Made Simple ❌ Before Next.js 16, developers manually handled caching using fetch with revalidation options — verbose and repetitive. ✅ Now, you can declare caching behavior directly in your component using "use cache" — cleaner and more readable. ✨ One line of code, same power — less confusion, better performance! #Nextjs #ReactJS #WebDevelopment #FrontendDevelopment #CleanCode #CodingTips #Nextjs16 #PerformanceOptimization #JavaScript #SoftwareEngineering #WebBestPractices

How I approach error boundaries in React React’s error boundaries prevent the entire UI from crashing due to one small bug. For large apps, this is a lifesaver. It’s a simple yet powerful concept that every React dev should implement. 👉 Do you use error boundaries in your apps? #ReactJS #ErrorHandling #Frontend #JavaScript

🚀 Mastering React? Don’t skip Strict Mode! Most devs overlook it, but Strict Mode silently saves your code from hidden bugs ⚙️ It catches unsafe actions, undeclared variables, and ensures your app runs smoother and safer. ✅ Helps write cleaner code ✅ Makes debugging easier ✅ Improves overall React app stability 💡 Tip: Use it early in development to avoid future headaches! #JavaScript #ReactJS #WebDevelopment #Frontend #CodingTips #LearnToCode #WebDevCommunity #DeveloperLife #CleanCode #JSDeveloper #ReactDev #100DaysOfCode

deploying a express.js + react web-app on vercel Services like Vercel and Render is pretty damn good for deploying your web-app especially if you have a low usage or for prototyping, and I recently had to get this done, so might as well document it here. First, let's start with the express.js backend. Let's say you have a GitHub repo with backend/ folder having a npm package with your express app, server.js is the main file to handle that, which should look like this: import express from 'express' const app = express() //all your middlewares, routes, controllers, etc... export default app Instead of defining the port, just export the express app object, vercel handles running that. Then define a vercel.json file to pinpoint the config that the server.js file is the main source (same dir as package.json in backend/): { "version": 2, "builds": [ { "src": "server.js", "use": "@vercel/node" } ], "routes": [ { "src": "/(.*)", "dest": "server.js" } ] } Although vercel by default looks https://lnkd.in/gVaKAuwQ

🚀 Creating a Basic HTTP Server in Node.js This code demonstrates creating a simple HTTP server using Node.js's built-in `http` module. The `http.createServer` method takes a callback function that is executed for each incoming request. Inside the callback, you can access the request object to get information about the request and the response object to send data back to the client. This example showcases a fundamental aspect of server-side Node.js development.
