Node.js ES Module Syntax with 'type': 'module'

📘 𝐉𝐚𝐯𝐚𝐒𝐜𝐫𝐢𝐩𝐭 𝐈𝐧𝐭𝐞𝐫𝐯𝐢𝐞𝐰 𝐌𝐨𝐝𝐮𝐥𝐞 (𝐁𝐚𝐬𝐢𝐜) -> Save this checklist, I hope it will be of great use in your next interview revision! 👇 𝐒𝐞𝐜𝐭𝐢𝐨𝐧 1: 𝐁𝐚𝐬𝐢𝐜 𝐉𝐚𝐯𝐚𝐒𝐜𝐫𝐢𝐩𝐭 (𝐓𝐡𝐞 𝐟𝐮𝐧𝐝𝐚𝐦𝐞𝐧𝐭𝐚𝐥𝐬 𝐨𝐟 𝐉𝐚𝐯𝐚𝐒𝐜𝐫𝐢𝐩𝐭) 🎯 𝐈𝐧𝐭𝐞𝐫𝐯𝐢𝐞𝐰 𝐐𝐮𝐞𝐬𝐭𝐢𝐨𝐧𝐬 (𝐄𝐱𝐭𝐫𝐚) 1. 𝐖𝐡𝐲 𝐢𝐬 𝐉𝐚𝐯𝐚𝐒𝐜𝐫𝐢𝐩𝐭 𝐜𝐚𝐥𝐥𝐞𝐝 𝐚 𝐬𝐢𝐧𝐠𝐥𝐞-𝐭𝐡𝐫𝐞𝐚𝐝𝐞𝐝 𝐥𝐚𝐧𝐠𝐮𝐚𝐠𝐞? -> JavaScript can only do one thing at a time. It has only one path (Call Stack). If the work of one line is not completed, it does not go to the next line. 2. 𝐖𝐡𝐚𝐭 𝐢𝐬 𝐞𝐯𝐞𝐧𝐭 𝐥𝐨𝐨𝐩 𝐢𝐧 𝐉𝐚𝐯𝐚𝐒𝐜𝐫𝐢𝐩𝐭? -> Suppose a task comes up in JavaScript that will take time (such as searching for data on the Internet). JavaScript puts that task aside and continues to do other tasks. When the task is completed, the Event Loop brings that data back to the main path. This is the event loop. 3. 𝐖𝐡𝐚𝐭 𝐢𝐬 𝐉𝐈𝐓 (𝐉𝐮𝐬𝐭-𝐈𝐧-𝐓𝐢𝐦𝐞) 𝐜𝐨𝐦𝐩𝐢𝐥𝐚𝐭𝐢𝐨𝐧? -> It compiles at run time and makes it fast. 4. 𝐖𝐡𝐲 𝐉𝐚𝐯𝐚𝐒𝐜𝐫𝐢𝐩𝐭 𝐢𝐬 𝐬𝐨 𝐩𝐨𝐩𝐮𝐥𝐚𝐫 𝐢𝐧 𝐰𝐞𝐛 𝐝𝐞𝐯𝐞𝐥𝐨𝐩𝐦𝐞𝐧𝐭? -> Because it runs everywhere—in browsers, servers (Node.js), mobiles (React Native), and even electronic devices. Its community is very large. 5. 𝐃𝐨𝐞𝐬 𝐉𝐚𝐯𝐚𝐒𝐜𝐫𝐢𝐩𝐭 𝐨𝐧𝐥𝐲 𝐫𝐮𝐧 𝐢𝐧 𝐛𝐫𝐨𝐰𝐬𝐞𝐫𝐬? -> No. Now with Node.js it can be run on PC or server as well. #DotNet #AspNetCore #MVC #FullStack #SoftwareEngineering #ProgrammingTips #DeveloperLife #LearnToCode #JavaScript #JS #JavaScriptTips #JSLearning #FrontendDevelopment #WebDevelopment #CodingTips #CodeManagement #DevTools

🚨 𝟗𝟓% 𝐨𝐟 𝐃𝐞𝐯𝐞𝐥𝐨𝐩𝐞𝐫𝐬 𝐆𝐞𝐭 𝐓𝐡𝐢𝐬 𝐖𝐫𝐨𝐧𝐠 𝐢𝐧 𝐉𝐚𝐯𝐚𝐒𝐜𝐫𝐢𝐩𝐭! Let me ask you something 👇 What does "function.length" actually return in JavaScript? Most developers think it counts the arguments passed ❌ But that’s not the full truth. 👉 It only counts the number of parameters defined 👉 And it completely ignores parameters after default values This small concept can easily become an interview trap if you're not clear about it. I’ve explained it with a simple example in this short video 👇 🎥 Watch here: https://lnkd.in/gtqaybpf If you're serious about improving your JavaScript fundamentals, start focusing on these small but powerful concepts. 💡 Because strong basics = strong developer. Comment “YES” if you already knew this, or "NEW" if you learned something today 👇 #javascript #webdevelopment #coding #frontend #nodejs #learnjavascript #programming #developers #softwaredeveloper #tech

I’ve been using these handwritten JavaScript notes to strengthen my understanding of code structure and core concepts. Whenever I encounter bugs or errors in my programs, I refer back to these notes to analyze how the code works and identify the appropriate patterns. I highly recommend that beginner JavaScript developers explore and download these notes—they can be a valuable resource for building a strong foundation.

🚨 JavaScript Tricky Question #3 (Advanced) What will be the output? 🤯 Promise.resolve() .then(() => { console.log("A"); throw new Error("Error!"); }) .catch(() => { console.log("B"); }) .then(() => { console.log("C"); }); Think carefully (this is tricky) 💬 Comment your answer 👇 🔁 Follow for daily advanced JS questions #javascriptdeveloper #mernstackdeveloper #frontendinterview #javascriptquestions #webdevelopmenttips #learnjavascript #jsconcepts #asyncjavascript #developersindia #codinginterview #softwaredeveloperlife #nodejsdeveloper #reactdeveloper #techcareers

Stop overcomplicating JavaScript functions! 🛑 Whether you're a beginner or brushing up for interviews, you need to know these 7 types like the back of your hand. From Hoisting in Declarations to the Pausing power of Generators, each has a specific use case that makes your code cleaner. Which one do you use the most? I’m definitely in the "Arrow Function everything" camp! 🏹 The Quick List: Declaration: The classic (and hoisted!). Expression: Assigned to variables. Arrow: Modern, sleek ES6 syntax. Anonymous: The "nameless" worker. IIFE: Runs the second it's born. Callback: The "call me back later" logic. Generator: The "pause and play" of JS. #JavaScript #WebDev #SoftwareEngineering #Frontend #Pyspider

Node.js already has threads running in the background. So why does worker threads exist? Swipe through to find out! #nodejs #javascript #backend #softwareDevelopment

⚡ JavaScript Tip: Cleaner Promise Error Handling Developers often use this trick to catch sync errors in promise chains. ❌ Before Promise.resolve() .then(() => JSON.parse(data)) .then(result => console.log(result)) .catch(err => console.error(err)); ✅ Now with Promise.try() Promise.try(() => JSON.parse(data)) .then(result => console.log(result)) .catch(err => console.error(err)); ✔ Less boilerplate ✔ More readable async flows ✔ Cleaner error handling Sometimes the best language improvements are the smallest ones. Would you start using Promise.try() in your projects? #JavaScript #ESNext #NodeJS #WebDevelopment #CodingTips

🚀 New Blog Alert for JavaScript Developers! Understanding this in JavaScript can feel like magic — until you truly get how call(), apply(), and bind() work. In this article, I break down these powerful concepts with simple explanations and practical examples you can actually use in real projects. 💡 👉 Read here: https://lnkd.in/dzxnYAqM If you’re learning JavaScript or preparing for interviews, this is a must-read! 🔥 Feedback and discussions are welcome 🙌 #JavaScript #WebDevelopment #Frontend #Coding #100DaysOfCode #LearnToCode

As developers, we can ship features for hours and forget to do the most basic human things. So I automated it. Here's what it does: *Runs every minute using node-cron *Speaks a reminder aloud using say *Greets you based on the time of day *Picks a random hydration message each time It's a small project, but it taught me a real lesson #NodeJS #javaScript #cronjob #say #Personaldevelopment
