JavaScript OOP Guide for Beginners

🚀 Just published a new blog on Understanding Object-Oriented Programming (OOP) in JavaScript. In this article, I explain the basics of OOP, including what classes are, how to create objects using classes, the constructor method, and methods inside a class. I also used simple real-world examples like blueprints and objects to make the concept easy to understand. 📖 Read the full article here: https://lnkd.in/gKUGBNMR Inspired by the amazing teaching of Hitesh Choudhary Sir and Piyush Garg Sir from Chai Aur Code . ☕💻 #javascript #webdevelopment #oop #learninginpublic #chaiAurCode

New blog on object-oriented programming in JavaScript. It covers the core ideas behind OOP, what it means, why it’s useful, and how concepts like objects, classes, and related behavior help structure code more clearly. If you’re learning JavaScript fundamentals, this might be helpful: https://lnkd.in/g7ARP9bJ Feedback is welcome. Chai Aur Code Hitesh Choudhary Piyush Garg

Day 70 of #100daysofcode Today I'll just be posting about a really great article that helped me better understand object oriented programming in JavaScript. At the end of the day, classes are just functions in JavaScript that return objects which contain prototypes. Prototypes store the methods and properties that can be accessed by all object instances of a particular class. This article below discusses more about object prototypes, getters, setters, and so much more! https://lnkd.in/d_NE3aTH In my next post, I will be posting the project requirements for my small todo list application.

I’ve broken it down step-by-step with practical examples, real-world analogies, and code snippets that actually make sense. Whether you’re a beginner trying to level up or an experienced dev looking for a solid refresher, I hope it helps clear things up! 🔗 Read it here: https://lnkd.in/gk4W-7_a Hitesh Choudhary Piyush Garg Akash Kadlag Suraj Kumar Jha Anirudh J.

🚀 Expanding My Programming Skills with JavaScript Arrays! After working on Python fundamentals, I’ve now started practicing **array-based programs in JavaScript** to strengthen my problem-solving skills and explore a new language. 💻✨ In this article, I’ve covered different array concepts such as: ✔️ Finding common and unique elements ✔️ Array merging, union & intersection ✔️ Moving zeros and handling edge cases ✔️ Finding pairs with a given sum ✔️ Sorting without built-in functions ✔️ Identifying majority and non-repeating elements This practice is helping me improve my logical thinking and understand how similar concepts work across different programming languages. Consistency and small efforts every day are helping me grow step by step 🚀 #JavaScript #CodingJourney #DataStructures #Programming #Learning #WebDevelopment #100DaysOfCode 1️⃣ Find Common Elements in Two Arrays let arr1 = [1, 2, 3, 4]; let arr2 = [3, 4, 5, 6]; let common = arr1.filter(num => arr2.includes(num)); console.log("Common Elements:", common); 2️⃣ Merge Two Arrays Without Duplicates let arr1 = [1, 2, 3]; let arr2 = [3, 4, 5]; let merged = [...new Set([...arr1, ...arr2])]; console.log("Merged Array:", merged); 3️⃣ Find the Largest Difference let arr = [2, 3, 10, 6, 4, 8, 1]; let min = arr[0]; let maxDiff = 0; for (let i = 1; i < arr.length; i++) { if (arr[i] - min > maxDiff) { maxDiff = arr[i] - min; } if (arr[i] < min) { min = arr[i]; } } console.log("Max Difference:", maxDiff); 4️⃣ Move All Zeros to End let arr = [0, 1, 0, 3, 12]; let result = arr.filter(num => num !== 0).concat(arr.filter(num => num === 0)); console.log("Result:", result); 5️⃣ Find Intersection of Arrays let arr1 = [1, 2, 2, 3]; let arr2 = [2, 2, 4]; let intersection = arr1.filter(num => arr2.includes(num)); console.log("Intersection:", intersection); 6️⃣ Find Union of Two Arrays let arr1 = [1, 2, 3]; let arr2 = [2, 3, 4]; let union = [...new Set([...arr1, ...arr2])]; console.log("Union:", union); 7️⃣ Find First Non-Repeating Element let arr = [4, 5, 1, 2, 0, 4]; let freq = {}; for (let num of arr) { freq[num] = (freq[num] || 0) + 1; } for (let num of arr) { if (freq[num] === 1) { console.log("First Non-Repeating:", num); break; } } 8️⃣ Find Pairs with Given Sum let arr = [1, 5, 7, -1, 5]; let target = 6; for (let i = 0; i < arr.length; i++) { for (let j = i + 1; j < arr.length; j++) { if (arr[i] + arr[j] === target) { console.log(arr[i], arr[j]); } } } 9️⃣ Sort Array Without Built-in Function (Bubble Sort) let arr = [5, 3, 8, 4, 2]; for (let i = 0; i < arr.length; i++) { for (let j = 0; j < arr.length - i - 1; j++) { if (arr[j] > arr[j + 1]) { let temp = arr[j]; arr[j] = arr[j + 1]; arr[j + 1] = temp; } } } console.log("Sorted Array:", arr);

Object-Oriented Programming (OOP) is still one of the most powerful ways to write scalable code — especially in TypeScript. But here’s the reality 👇 👉 Many developers use TypeScript… 👉 Few actually use OOP effectively. So I wrote a simple, practical guide covering: ✅ Core OOP concepts (Encapsulation, Inheritance, Polymorphism, Abstraction) ✅ Real-world TypeScript examples ✅ Interfaces & best practices ✅ When to use (and avoid) OOP If you're building scalable apps with Angular, Node.js, or any large system — this will help 👇 🔗 Read here: https://lnkd.in/dWzaiqEk 💬 What’s your take — do you prefer OOP or functional programming? #javascript #typescript #webdevelopment #programming #softwareengineering #angular #nodejs

Everyone says “learn coding”. But what should you actually learn? Here are some skills that are really in demand right now: → Web Development (HTML, CSS, JavaScript, React) → Java / Python (for backend & logic building) → SQL (very important for data handling) → Git & GitHub (for projects and collaboration) → APIs (how apps communicate) Bonus : Git commands for tracking every version of your files so you can collaborate safely, revert mistakes, and manage experimental changes without breaking your project If you're in IT, don’t just learn randomly.
