Arrays and Objects: Accessing Index and Value with entries() method

In JavaScript, Reference Data Types say: “If you change me… I will change the every refrences of yours. 😏 Sounds dramatic? Look at this 👇 let a = [1, 2, 3, 4]; let b = a; b.pop(); console.log(a); console.log(b); comment down the output?? #javascript #coding #learntocode #programming #datatypes #learninginpublic

Sharing beginner-friendly notes on Object-Oriented Programming (OOP) in JavaScript 🧠 Covered core concepts like Classes, Constructors, Inheritance, Encapsulation, Polymorphism, Getters/Setters, Static methods, and Private fields (#) with clear examples. Also explained how super, instanceof, and prototypes work behind the scenes. A practical guide to understanding how OOP works in modern JavaScript.

🚀 Day 21 - Poll answer & Explanation function sum() {  var i, l, result = 0;  for (i = 0, l = arguments.length; i < l; i++) {  result += arguments[i];  }  return result; } console.log(sum(1, 2, 3)) // 6 Explanation (simple & clear): - "arguments" is an array-like object holding all passed values. - Loop runs from 0 to arguments.length. - Each value is added to "result". - 1 + 2 + 3 = 6 Key Point: - Works without defining parameters explicitly. - "arguments" is NOT a real array (no map/filter).

💡 JavaScript Trick: Move all zeros to the end of an array const arr = [0, 0, 0, 1, 2, 3, 4]; const result = [ ...arr.filter(item => item !== 0), ...arr.filter(item => item === 0) ]; console.log(result); ✅ Output: [1, 2, 3, 4, 0, 0, 0] #javascript #coding #webdevelopment #programming #frontenddeveloper #react

I wrote a small JavaScript example to practice callbacks and asynchronous programming. The code simulates fetching a user’s data step by step: first the ID, then the name, then the surname.

30 Days JavaScript Challenge: Day 25 ✅ Today’s problem was about merging two arrays of objects based on a common key (id). Sounds simple at first, but it had a few interesting parts: Handling unique ids Merging objects when ids match Making sure values from the second array override the first Keeping everything sorted It’s actually very close to real-world scenarios like combining data from two APIs or updating existing records with new data. Problems like this make you think more about data handling and structure, not just loops and conditions. Day by day, things are starting to connect better. 🚀 #javascript #leetcode #webdevelopment #frontenddeveloper #codingchallenge #learninginpublic #developers #programming #buildinpublic #JavaScriptMastery

Just published a new article on Object-Oriented Programming in JavaScript. It covers: • Classes & Constructors • Object Creation • Inheritance, Encapsulation, Abstraction, Polymorphism All explained with simple car-based examples to make OOP easier to understand.

VS Code extensions are a bit like kitchen knives. You don't need 47 of them. You need the three that actually work. Windsurf's new extension guidance just dropped, and it's refreshingly honest about this. No "unlock your potential with 200 plugins" nonsense. Just a curated list of what actually helps devs across Python, Java, C#, and the rest. What caught me? They're not pushing their own ecosystem. They're pointing to the Open VSX Registry and saying "go build your own stack." That's rare. Most tools want to lock you in. The practical wins are obvious. GitLens for code history. Ruff for Python linting. The Java Extension Pack if you're knee-deep in enterprise code. But the real value isn't the list itself. It's the admission that context matters. A Python dev's setup looks nothing like a Java dev's. Pretending otherwise is just noise. I've seen teams waste weeks hunting for the "perfect" IDE setup when the real bottleneck was bad code reviews and no pair programming. Extensions are just force multipliers on top of solid fundamentals. If you're onboarding developers or setting up a new machine, this beats the usual "install everything" approach. Worth a bookmark. https://lnkd.in/eR_F_Eeg

🚀 JavaScript Fundamentals Series — Part 6 Arrays are how JavaScript stores lists of data. Almost every real application uses arrays. This guide explains: • How arrays work internally • Accessing and updating values • Looping through arrays • Common array mistakes If you understand arrays well, working with data becomes much easier.

🚀 Day 22 - Poll answer & Explanation const map = new Map(); map.set("a", 1); map.set("b", 2); const set = new Set([1, 2, 3, 3]); console.log(map.size, set.size); 2 3  Explanation (simple & clear):  - Map stores key-value pairs → "a" and "b" → size = 2  - Set stores only unique values → duplicates removed  - [1, 2, 3, 3] → becomes [1, 2, 3] → size = 3  Key Point:  - Map counts unique keys  - Set automatically removes duplicate values  Output:  2 3 #JavaScript #JSInterview #FrontendDevelopment #WebDevelopment  #CodingChallenge #JSConcepts #Developers #Programming  #TechInterview #LearnJavaScript #100DaysOfCode #CodeNewbie  #SoftwareDevelopment #CodingTips #JSBasics #DevelopersLife
