Day 8 of making my self a BRAND 1 : Node js works with modules, there are core modules which are built in modules and external modules which can be installed from some package manager like npm, pnpm, yarn etc 2 : commonly used built in modules are fs, http, https, path etc 3 : commonly used external modules : express, dotenv, mongoose etc 4 : ask AI to list common modueles 5 : You might have heared about async in js but have you ever asked why it even exist, every body knows that async is which runs in the background but why to even run in the background. 6 : The reason that it exists because js in single threaded on browser and in node js environment as well so not to block the call stack in which the code is executed we use async in js #Nodejs #JavaScript #AsyncJS #WebDevelopment #BackendDevelopment #FullStackDevelopment #Coding #Programming #Developers #TechCommunity #NodeModules #CoreModules #ExpressJS #NPM #NodeTips #LearnNodeJS #NodeDeveloper #ServerSide #BackendEngineer #JavaScriptRuntime #100DaysOfCode #CodeNewbie #LearningInPublic #DeveloperJourney #SelfImprovement #BuildInPublic #CodingJourney #SkillUp #ContinuousLearning #TechEducation #AsyncProgramming #EventLoop #Concurrency #SingleThreaded #NonBlockingIO #WebServers #CodeBetter #DevTips #TechInsights #ProgrammingConcepts #Day8 #MakeYourselfABrand #PersonalBranding #DeveloperBrand #CodingMindset #ConfidenceInCoding #TechCareer #GrowthMindset #MotivationForDevelopers #LearnBuildGrow

🧵 Understanding Threads in Node.js – The Power Behind the Scenes When people hear “Node.js is single-threaded”, they often assume it can only handle one task at a time. But that’s only part of the story. Node.js runs JavaScript code in a single main thread, but under the hood, it uses libuv — a powerful C library that manages a thread pool for handling I/O operations efficiently. That’s why Node can serve thousands of concurrent requests without breaking a sweat 😎 💡 With the introduction of Worker Threads, Node.js now lets you run CPU-intensive tasks in parallel — without blocking the event loop. Perfect for data processing, image manipulation, or machine learning workloads. So next time someone says “Node can’t do multithreading,” you’ll know better 😉 🚀 Threads + Event Loop = Scalable Power #NodeJS #JavaScript #WebDevelopment #SoftwareEngineering #BackendDevelopment #Programming #Developers #Concurrency #Async #TechInsights #cfbr

🚀 Leveling Up My Node.js Understanding: Beyond “It Just Works” Over the past few days, I’ve been digging really deep into Node.js — not just building APIs, but understanding what’s actually happening under the hood when Node handles concurrency and scalability. I kept hearing about: Worker Threads Child Processes Clusters …and I finally took the time to understand what each really does — and why they exist. 💡 Worker Threads → For CPU-heavy JavaScript tasks like hashing or image compression — real multithreading inside a process. 💡 Child Processes → For running external programs or scripts (Python, ffmpeg, another Node file) — separate memory, separate process. 💡 Cluster Module → For scaling Node.js servers across all CPU cores, with automatic load balancing handled by Node itself. Together, these three make Node.js capable of both concurrency and parallelism — when used wisely. It’s fascinating to see how far Node can go when you stop just coding and start thinking about system design and scalability. Next up: experimenting with a cluster + worker_threads architecture for true high-performance backend processing ⚡ Because being a developer isn’t about just “making it work” — it’s about understanding why it works and how to make it scale. #NodeJS #BackendDevelopment #JavaScript #Scalability #Concurrency #Performance #CleanArchitecture #DeveloperMindset #LearningJourney

🔁 JavaScript Loops — They Literally Put Me in a Loop 😅 Started learning loops today, and wow… they’re the real deal when it comes to writing less code that does more! ⚙️ Loops basically say: > “Why write it ten times when I can do it for you?” 😎 Here’s what I explored 👇 🔹 for loop — when you know exactly how many times to run 🔹 while loop — keeps going as long as the condition’s true 😆 🔹 do...while — runs at least once, no matter what 🔹 for...of / for...in — the cleanest way to loop through arrays and objects It’s crazy how something so simple can automate so much logic 🔄 Feeling one step closer to thinking like a developer now 💪 Next stop → Functions, where the real magic begins! ✨ #JavaScript #WebDevelopment #Frontend #CodingJourney #Loops #Programming #LearningInPublic #DeveloperLife #CleanCode #100DaysOfCode

🔥 Next.js 16 is here With Turbopack as default, projects build insanely fast ⚡ New “use cache” directive changes how caching works 🧠 Plus, proxy.ts, streamed metadata, and smarter routing make apps smoother than ever. It’s fast, modern, but yeah, upgrading from v15 needs a bit of care 👀 Explored it in detail, trust me, this version really pushes Next.js to the next level 🚀 🔗 Official Release: nextjs.org/blog/next-16 #Nextjs16 #Nextjs #React #WebDevelopment #Frontend #JavaScript #DevCommunity #Coding #Performance #Developers #Vercel #WebApps #TypeScript #WebPerformance #CodingCommunity #TechTrends #technology #innovation #future #digitaltransformation #technews #techtrends #engineering #programming #webdevelopment #techcommunity #frontend #backend #devlife #webdev #appdevelopment #machinelearning #deeplearning #neuralnetworks #datascience #automation #generativeai #chatgpt #openai #aidevelopment #aitechnology #futureofai #aitrends #aiinnovation #aiforbusiness #softwaredeveloper #softwareengineering #coding #programmer #developer #javascript #reactjs #nextjs #nodejs #typescript #python #cleanarchitecture #devcommunity #github #opensource #code #learning #careerdevelopment #techcareer #upskilling #motivation #linkedincommunity #personalbranding #jobsearch #growthmindset

🔥 Smallest Missing Multiple of K in JavaScript - 👉 Day 15 / Day 93 👈 👉 Given an integer array nums and a number k, return the smallest positive multiple of k that’s missing from nums. 🧠 Key idea: - Store numbers in a Set for constant-time lookup. - Increment through multiples of k until a missing one is found. #JavaScript #LeetCode #CodingChallenge #ProblemSolving #Algorithms #DataStructures #FrontendDeveloper #CodeNewbie #Programming #Tech #frontend #Angular #AngualrDeveloper

Diving deep into the Node.js Event Loop! ⚙️ Understanding this core concept is CRUCIAL for writing efficient and scalable server-side JavaScript. Ever wonder why Node.js can handle so many concurrent requests? It's all thanks to the event loop and its NON-BLOCKING I/O model. 🤯 Here are three key things to remember: 🔷 Understand the phases: Timer, Pending callbacks, Idle, Prepare, Poll, Check, Close callbacks. 🔷 Distinguish `setImmediate` vs `setTimeout(0)`: `setImmediate` is designed to execute after every poll phase. 🔷 Mind the `UV_THREADPOOL_SIZE`: Adjusting the thread pool size can optimize performance for CPU-intensive tasks.

🔥 Inside the V8 Engine — The Power Behind Node.js 🟢 Post 5/50 – 50 Days of Modern JavaScript Engineering 💡 Why is Node.js so fast? Because of V8 — the engine that turns JavaScript into machine code. ⚙️ How it works (step by step): 1️⃣ JavaScript Code → your source. 2️⃣ Ignition Interpreter → creates bytecode to run instantly. 3️⃣ TurboFan Compiler → optimizes repeated (“hot”) code paths. 4️⃣ CPU Machine Code → executes natively at full speed. 🚀 That’s why Node.js can handle huge loads while staying lightweight. 👉 Next: Post 6/50 – libuv & The Magic of Async I/O Follow Fuhaid Ur Rehman for daily Node.js insights and career-focused learning. #Nodejs #JavaScript #BackendDevelopment #V8Engine #FullStack #OpenToWork #WebDevelopment #NestJS #ReactJS #MongoDB #PostgreSQL
