Why does this print 4 4 4 4 in JavaScript? 🤯 A small setTimeout() + var question that teaches a big concept: closures, scope, and async behavior. When you understand why it happens, JavaScript starts making much more sense. #JavaScript #WebDevelopment #Programming #Coding #FrontendDevelopment #SoftwareEngineering #Developer #TechCommunity #LearnToCode #AsyncJavaScript #Closures #SetTimeout #100DaysOfCode #CodingTips #JavaScriptDeveloper

Most JavaScript problems aren’t about complexity. They’re about fundamentals. Common mistakes I still see: Using == instead of === Not understanding scope Poor async handling Callback hell Fixing these will improve your code quality instantly. Master the basics → everything else becomes easier.

this in JavaScript looks simple… until it starts pointing to the wrong thing 😵 Same function, different outputs — just because of how it’s called. So what does this actually mean? 👉 It’s not about where the function is written 👉 It’s about who is calling the function In this blog, I’ve explained: What this really represents this in global context this inside objects and functions How calling context changes everything Kept it simple with clear examples (no unnecessary theory) ✨ 🔗 Read here: https://lnkd.in/dMkPffeA Would appreciate your feedback 🙌 #javascript #webdevelopment #programming #coding

30 Days JavaScript Challenge : Day 24 ✅ Today’s problem was about sorting an array using a custom function. Instead of directly sorting values, we use a function fn to decide the order — basically telling JavaScript how to compare elements. At first it feels simple, but it actually shows how powerful sorting can be when you control the logic: Sorting objects based on a property Sorting nested arrays Custom ranking based on conditions It’s one of those concepts that looks basic but is used everywhere in real projects. Slowly getting more clarity on how to write flexible and reusable logic in JavaScript. #javascript #leetcode #webdevelopment #frontenddeveloper #codingchallenge #learninginpublic #developers #programming #buildinpublic

What are variables in JavaScript? Variables in JavaScript are used to store data that can be used and updated in your program. They act like containers for values such as numbers, strings, or objects. You can declare variables using let, const, or var. let allows changes, const is for values that shouldn’t change, and var is older and less commonly used. Choosing the right one helps avoid errors. Variables make your code flexible and reusable, allowing you to store user input, perform calculations, and manage data efficiently. #webdeveloper #tech #coding #programming
