Understanding Prototypes & Classes in JavaScript

Today, I explored one of the most important concepts in JavaScript — Object-Oriented Programming (OOP) and Classes! 🚀 I learned how to: Create and use classes in JavaScript Work with constructors, methods, and objects Understand core OOP pillars — Encapsulation, Inheritance, Polymorphism, and Abstraction Build small examples like student management and product models It was amazing to see how OOP makes code more organized, reusable, and scalable. 💡 Next, I’ll be diving deeper into how these concepts are used in real-world projects and React components. #JavaScript #OOP #WebDevelopment #LearningJourney #PlacementPreparation #Developer Hitesh Choudhary

🗓️ Day 21 of JS Series by Rohit Negi 📔 What I Learned: ✅ What a prototype is ✅ How the prototype chain works ✅ The concept of inheritance using prototypes ✅ How JavaScript can provide property and method suggestions even if they aren’t explicitly defined (because of the prototype chain) ✅ In JavaScript, almost every data type (except null and undefined) is derived from the Object type ✅ Learned the basics of OOP (Object-Oriented Programming) concepts in JavaScripttype (except null and undefined) is derived from the Object type. ✅ Learn Oops concept #JavaScript #WebDevelopment #LearnInPublic

Day 3 – JavaScript Loops Practice In this task, I practiced different types of JavaScript loops — for, while, do...while, and for...of — to understand how iteration works in programming. I applied loops to solve small problems like counting numbers, iterating over arrays, and displaying patterns in the console. This practice improved my logic-building skills, debugging techniques, and understanding of flow control in JavaScript. Key Learning Areas: Difference between for, while, and do...while loops Using loops with arrays and objects Avoiding infinite loops and understanding loop conditions Real-time testing using console.log() #JavaScript #WebDevelopment #FrontendLearning #CodingChallenge #Loops #CodingJourney #WomenInTech #100DaysOfCode

Day 76 of #100DaysOfCode Today, I explored the fundamentals of Functional Programming in JavaScript — focusing on writing cleaner, more predictable, and testable code. Key takeaways: Pure Functions: Always return the same output for the same input and don’t modify anything outside themselves. Side Effects: Any interaction with the outside world (like modifying global variables or logging to console). Reducing side effects makes programs easier to maintain. Currying: Transforming a function with multiple arguments into a series of functions that each take a single argument. It allows for partial application, where you can preset certain parameters to create reusable, specialized functions. Functional programming promotes modular, reusable logic, helping you build code that’s both elegant and easier to reason about.

I used to think JavaScript was an asynchronous language. Turns out, it’s actually synchronous by design. It executes one line at a time in a single thread. But here’s where it gets cool. Thanks to the event loop and features like callbacks, promises, and async/await, JavaScript can handle asynchronous tasks without freezing the page. So while one task runs, another can wait in line without blocking the main thread. In other words, JavaScript behaves synchronously but can act asynchronously. That balance is what makes it so powerful on the web. Other languages: Python and Ruby are mostly synchronous. Go and Rust support true parallelism. C++ and Java use multithreading. But JavaScript is unique. It doesn’t just run code, it choreographs it. These complex dynamics are what make picking JavaScript as my first language worth it. Behind every smooth animation, instant search result, or real-time notification, there’s a little async magic doing the heavy lifting. And once you understand the event loop, it honestly feels like you’ve unlocked one of programming’s secret cheat codes. #JavaScript #WebDevelopment #Coding #AsyncJS #SoftwareEngineering #ProgrammingHumor #TechMindset #WTFC25

One of the most valuable features of functional programming is the ability to work with lazy sequences. Today, nearly every programming language supports generics, functions as values, and iterators. These are essential building blocks for operators that work with lazy sequences. In the next series of posts, we will build my JavaScript library, powerseq, from scratch. https://lnkd.in/dTdM5snr

💻 Exploring JavaScript Operators and Functions! 🚀 Today I practiced different types of operators and functions in JavaScript, including: ✨ Arithmetic Operators ( + , - , * , % ) ✨ Logical Operators ( && , || , ! ) ✨ String Concatenation ✨ Custom Functions for addition, subtraction, multiplication, and division This helped me understand how JavaScript performs calculations, comparisons, and combines strings — all fundamental skills for any developer! 🧠 Every line of code teaches something new. #JavaScript #WebDevelopment #CodingJourney #LearnToCode #Programming #JSBasics

Day 8 of #30DaysOfJavaScript on LeetCode Today's challenge: 2629 — Function Composition The task was to implement a function that takes an array of functions [f1, f2, f3, ..., fn] and returns a new function that represents their composition. In simple terms, the composed function should apply all the given functions from right to left, just like: f(g(h(x))) Here’s my solution 👇 var compose = function(functions) { return function(x) { let res = x; for (let i = functions.length - 1; i >= 0; i--) { res = functions[i](res); } return res; } }; This challenge gave me a deeper understanding of how function chaining and composition work in JavaScript — building complex logic from smaller, reusable functions. It’s a beautiful example of how functional programming principles simplify problem-solving!
