Building Pulse — a small language for deterministic concurrency in JavaScript Over the last few months, I’ve been working on something I’ve always wished JavaScript had by default: deterministic concurrency. In most cases, JS async behavior depends on the event loop, Promise.race, or microtasks. That means timing, order, and scheduling aren’t truly predictable - even if your code looks flawless. Small differences can change execution order in ways that are hard to trace. Pulse is a small experimental language that compiles to JavaScript (ES Modules) but runs on its own deterministic runtime. Under the hood, it’s reactive like Solid or Svelte, but it also brings in Go-style concurrency as a first-class concept. Why I built Pulse I spend most of my time switching between JavaScript and Python. I wanted something that felt as expressive as JS, but with concurrency I could actually rely on - no hidden race conditions or random task order. When I say deterministic, I mean that the same program should behave the same way every time it runs. No invisible timing gaps, n https://lnkd.in/dx7PhMd4

🗓️ 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 

🚀 Learning JavaScript: Practicing “for loops”! Today, I worked on different examples using for loops in JavaScript — a powerful tool for repeating tasks efficiently. Here’s what I explored 👇 💡 Tasks I completed: 1️⃣ Printed even numbers from 2 to 20 2️⃣ Printed odd numbers from 1 to 19 3️⃣ Calculated the square of numbers from 1 to 5 4️⃣ Found the sum of numbers from 1 to 10 5️⃣ Calculated the product of numbers from 1 to 5 6️⃣ Printed the cube of numbers from 1 to 5 7️⃣ Displayed numbers from -5 to 5 🧠 This exercise helped me understand how iteration, increment, and logical conditions work together in JavaScript loops. 🌱 Every small project like this helps strengthen my programming logic and problem-solving skills! #JavaScript #CodingJourney #ForLoop #WebDevelopment #100DaysOfCode #FrontendDevelopment #LearnToCode

💻 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

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

Dr. James McCaffrey presents a complete end-to-end demonstration of ANOVA (analysis of variance) using JavaScript. ANOVA is a classical statistical technique where the goal is to determine if the unknown means (averages) of three or more groups are likely to all be equal or not, based on the variances of samples from the groups.

💡 Encapsulation & Polymorphism — Bringing Structure to JavaScript After getting comfortable with Classes, I dived into how Encapsulation and Polymorphism bring real shape and discipline to Object-Oriented Programming (OOP) in JavaScript. 🚀 🔒 Encapsulation taught me the importance of protecting and controlling data — using private fields (#) and getters/setters to manage access. It’s like setting healthy boundaries inside your code — clean, safe, and predictable. 🎭 Polymorphism showed me the power of flexibility — where different classes can share the same method names but behave differently based on context. It’s creativity meeting structure — and it makes your code truly adaptable. ✨ Together, they transformed my code from scattered logic into a well-organized, reusable system that actually feels designed. 💬 “Good code isn’t just about working — it’s about being organized, reusable, and scalable.” #JavaScript #OOP #Encapsulation #Polymorphism #FrontendDevelopment #CleanCode #CodingJourney #LearnInPublic #Developers

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
