Just published a new article: Node.js: The New Era of JavaScript Runtime Environments. In this article, I cover: What a browser receives from a server (HTML, CSS, JavaScript) Why JavaScript traditionally ran only in the browser How Node.js made it possible to run JavaScript on the server The high-level role of V8 and system APIs in Node.js #nodejs #javascript #webdevelopment #backend #programming

Day 5 of 100 days. A situation many developers encounter when working with JavaScript, especially at the early stages… You write your code, trigger an action, and expect a response - but nothing happens. No error. No output. Just silence. And it’s not just beginners - this is a common experience across all levels. The challenge: JavaScript not responding 👉 What I always advise: • Ensure your script is properly linked • Confirm the DOM has fully loaded before running your code • Use console.log() to trace and debug your logic Often, the issue isn’t complex - it’s simply hidden. Do you use console.log() when debugging, or do you have another favorite method?

A quick async themed JavaScript bug hunt. We log a few values, schedule a setTimeout with zero delay, and resolve a Promise. Nothing looks unusual, but the output order might be unexpected. What order do the four strings print in, and why? Check it out and share your answer in the comments.

🚀 Just built a Password Generator using JavaScript! This project generates strong and secure passwords with customizable length and character options. Great practice for improving my JavaScript, DOM manipulation, and logic building skills. 🔹 Features: • Random strong password generation • Adjustable password length • Clean and simple UI Always learning and building! 💻✨ #JavaScript #WebDevelopment #Coding #FrontendDevelopment #password #passwordgenrater

If JavaScript runs on one thread… why doesn’t your app freeze during API calls? Most people think: “JavaScript is single-threaded… but somehow works like multithreading.” That’s not entirely true. JavaScript doesn’t do multithreading — it handles concurrency. Here’s the difference: Multithreading (Java): • Multiple threads run at the same time • Tasks execute in parallel • Output is unpredictable and interleaved JavaScript (Event Loop): • One thread only • Long tasks are delegated to the runtime • Results are processed later via the event loop So what’s really happening? JavaScript avoids waiting. Instead of doing everything itself, it: • Delegates slow work (timers, APIs, I/O) • Keeps executing other code • Handles results when they’re ready That’s why it feels like multiple things are happening at once. But in reality: → No parallel execution → No thread switching → Just smart scheduling Understanding this changes how you write async code.

🚀 Day 979 of #1000DaysOfCode ✨ 4 Useful Number Functions in JavaScript (With Cool Examples) JavaScript provides many built-in number utilities — but most developers only use a few of them. In today’s post, I’ve shared 4 super useful number functions in JavaScript along with some cool and practical examples for each. These functions can help you handle number validation, formatting, and edge cases more effectively in real-world applications. Small utilities like these might look simple, but they can save you time and help you write cleaner and more reliable logic. Once you start using them properly, you’ll notice how often they come in handy while working with data. If you work with numbers, calculations, or user inputs in JavaScript, these functions are definitely worth knowing. 👇 Which JavaScript number function do you use the most in your projects? #Day979 #learningoftheday #1000daysofcodingchallenge #FrontendDevelopment #WebDevelopment #JavaScript #React #CodingCommunity #JSDevelopers

Do You Really Understand the JavaScript Event Loop? 🤔 Most developers use async code daily… but few truly understand what happens behind the scenes.

Node.js REPL is underrated. Need to test a function? Try a package? Debug a snippet? Just type: node Interactive JavaScript shell. No setup required. Simple tools. Powerful results. #NodeJS #REPL #DeveloperTools

🚀 Day 2/30 – JavaScript Challenge LeetCode Problem: 2620 – Counter Today I learned about one of the most important concepts in JavaScript Closures. 🔹 Concept Explained: The inner function remembers the variable number even after the outer function has finished execution. This is called a closure. 🔹 Key Learnings: ✅ Closures help maintain state without global variables ✅ Useful in counters, ID generators, and real-world applications ✅ number++ returns the current value, then increments it #Leetcode #Day2 #JavaScript #Developers #Frontend

JavaScript: Mirror Distance Problem Day 5 👈 Goal: Find the mirror distance of a number — the absolute difference between the number and its reversed form. Approach: Reverse the given number using modulo (%) and division. Subtract the reversed number from the original. Take the absolute value to ensure a positive result. Example: Input: 123 Reversed: 321 Mirror Distance: |123 - 321| = 198 #JavaScript #TypeScript #DSA #CodingInterview #ProblemSolving #FrontendDevelopment #Developers #100DaysOfCode
