Optimize Node.js with Promise.all() for async code

✨ Master JavaScript Array Destructuring for Cleaner Code Modern JavaScript lets you extract values in one line—making your code shorter, clearer, and easier to maintain. 🧠 Why it matters: Readable code = fewer bugs + faster development. ⚛️ If you’re using React, you’re already using destructuring (useState, useReducer). #JavaScript #FrontendDevelopment #WebDevelopment #ReactJS #CleanCode #ModernJS #SoftwareEngineering

you called setState twice. expected +2. got +1. both calls read the same stale count from the current render. they don't compound. they both say "set to 1." welcome to React. why it breaks: state updates don't happen immediately. they're scheduled. so count is still 0 inside your function no matter how many times you call setState. both calls read 0. both set to 1. result: 1. the Fix: use functional updates. each call gets the previous result and builds on it.

Day 65/100 – Starting with Node.js 🚀 Learned: What Node.js is and how it allows JavaScript to run outside the browser Basic idea of the Event Loop and how Node handles multiple requests efficiently Introduction to Express and how it simplifies backend development What stood out: Node.js doesn’t work like traditional synchronous systems. Instead of waiting, it handles tasks asynchronously using the event loop, making it fast and scalable. #NodeJS #BackendDevelopment #JavaScript #LearningInPublic #100DaysOfCode

⚛️ React Components Explained In React, everything is built using components. There are two types: • Functional Components – simple, modern, and use Hooks • Class Components – older, more complex, and less used today 👉 Today, developers prefer Functional Components for clean and scalable code. Are you using functional components in your projects? #ReactJS #FrontendDevelopment #JavaScript #WebDevelopment #Coding

Most developers think the key prop in React is just for lists. But one small mistake with keys can silently destroy your frontend performance and increase load time without you realizing it. I’ve seen apps where random keys caused full component remounts on every render — and debugging that was painful. If you're using Math.random() or changing keys unnecessarily this post might save you hours of debugging. #react #frontend #reactjs #javascript #webdevelopment #frontenddeveloper #softwareengineering #codingtips

🚀 React Hooks Explained (Intermediate Level) I’ve been learning React deeply and created simple notes about: ✅ useEffect (Side Effects) ✅ useRef (DOM & Mutable Values) I simplified concepts with examples and real use cases. If you're learning React, this will help you understand hooks faster 💡 #React #WebDevelopment #JavaScript #Frontend

React Tip: Use Functional Updates When new state depends on previous state: javascript // Wrong way setCount(count + 1); // Right way setCount(prevCount => prevCount + 1); Why? React batches updates. Functional updates ensure you always have the latest value. #ReactJS #FrontendDeveloper #CodingTips

Starting My React.js Journey – Basics with Code! Today, I revisited the fundamentals of React.js, and I believe mastering the basics is the key to building powerful applications. Sharing a quick snippet that demonstrates how simple and clean React can be import React from "react"; function Welcome() { const name = "Developer"; return ( <div> <h1>Hello, {name} </h1> <p>Welcome to React Basics!</p> </div> ); } export default Welcome; What this covers: - Functional Components - JSX (JavaScript + HTML) - Dynamic Data Rendering using variables Key Learning: React is not just a library — it's a mindset of building reusable and maintainable UI components. Next Steps: - Props & State - Event Handling - Component Lifecycle Consistency beats intensity. Small steps every day = Big growth #ReactJS #WebDevelopment #JavaScript #Frontend #CodingJourney #100DaysOfCode

Node.js vs NestJS — Which should you pick in 2026? 🔥 Both are powerful. Both run JavaScript on the server. But they serve very different purposes. Here's a quick breakdown 👇 🟢 Node.js → Raw, flexible, minimal. You build the rules. 🩷 NestJS → Structured, opinionated, enterprise-ready. → Same runtime. Completely different experience. If you're building a quick API or a real-time tool → go with Node.js. If you're building something that needs to survive a growing team → NestJS is worth the learning curve. Which one are you using right now? Drop it below 👇 #NodeJS #NestJS #JavaScript #TypeScript #BackendDevelopment #WebDev #SoftwareEngineering #100DaysOfCode
