JavaScript Operators: Mastering Logic and Calculations

Just published a new blog on JavaScript Arrays. When we start programming, we often store values like this: let movieOne = "Inception" let movieTwo = "Interstellar" let movieThree = "Dune: Part Two" This works for small data, but imagine storing 50 movies or 100 student marks. Managing individual variables quickly becomes messy. That is where arrays help. In this blog I covered: What arrays are in JavaScript Different ways to create arrays Accessing elements using indexes Updating array values Understanding the length property Looping through arrays using a simple for loop Arrays are one of the most commonly used data structures in JavaScript and understanding them early makes working with data much easier. link: https://lnkd.in/dYQtZ4P6 #javascript #coding #programming #learninpublic #chaicode

I recently wrote a short blog explaining Object-Oriented Programming in JavaScript and its four core principles: Encapsulation, Inheritance, Polymorphism, and Abstraction, with simple examples. If you're learning JavaScript or revising OOP concepts, this article might be helpful.

🌌 What if JavaScript variables were books in a library? Some books can be rewritten. Some are locked forever. Some are shared by many readers. And some quietly disappear when no one remembers them. That’s surprisingly close to how JavaScript variables and memory actually work. I explored this idea through a short story inspired by The Midnight Library. 📖 Read the blog:https://lnkd.in/g46v5jfp #JavaScript #Programming #LearnInPublic #chaicode Hitesh Choudhary Piyush Garg Akash Kadlag

While learning JavaScript, I found a simple way to understand how it runs compared to other programming languages. Think about C or C++ first. In those languages, the code is usually compiled before execution. That means the whole program is translated into machine code first, and only then the computer runs it. So the flow is like this: Write code → Compile → Run JavaScript works in a more dynamic way. JavaScript engines like V8 do not always compile everything in advance like C++. Instead, they start reading and running the code, and then optimize the parts that are used most often with JIT (Just-In-Time) compilation. So JavaScript is more like: Write code → Start running → Optimize while running That is what makes JavaScript interesting. Other languages often prepare everything before execution. JavaScript can begin execution quickly and improve performance along the way. A simple way to think about it: C/C++ = prepare everything before the exam JavaScript = start writing, then get faster and smarter while solving Learning this made me realize that programming is not only about writing code. It is also about understanding what happens behind the scenes. #JavaScript #Programming #WebDevelopment #Coding #LearningJourney #SoftwareEngineering

You’ve probably heard this before: “var is function scoped” “let is block scoped” But… what does that actually mean? This is one of the most common JavaScript interview questions And honestly, many people just memorize it without really understanding it So I recorded a tutorial video where I explain: • What scope really means • Difference between function scope and block scope I’m also trying to improve how I explain technical concepts So if you watch it, I’d really appreciate your feedback: Was it easy to understand? Anything I can improve? Your feedback will help me make better videos This is the demo video. Complete tutorial is available on my YouTube channel.

30 Days JavaScript Challenge : Day 17 ✅ Today’s problem was about designing a Time Limited Cache. The idea was to store key-value pairs, but with a twist each key should expire after a certain time. The class needed to support: • setting values with an expiry • retrieving values only if they’re still valid • counting how many keys are currently active This felt closer to a real-world problem, especially how caching systems work with expiration. It was interesting to think about how to manage time, state, and updates together in a clean way. 17 days in learning not just syntax, but how to think through problems. 💻🚀 #javascript #leetcode #webdevelopment #frontenddeveloper #codingchallenge #learninginpublic #developers #programming #buildinpublic

Programming is more than just writing lines of code; it's about making decisions. 🚦 In my latest blog post, I dive deep into Control Flow in JavaScript. I break down how if, else, and switch statements act as the "GPS" for your code, directing logic based on real-world scenarios. What you’ll learn: ✅ The logic behind if-else vs. switch ✅ Why the break keyword is a lifesaver in switch cases ✅ A side-by-side comparison for cleaner code Perfect for beginners or anyone looking to sharpen their JS fundamentals! 🚀 Read more here: https://lnkd.in/dwuvC9jq #JavaScript #WebDevelopment #Programming #BeginnerCode #LearningToCode #Hashnode

🚀 Understanding JavaScript Objects – A Beginner’s Guide Blog Linke :~ https://lnkd.in/gC94PJCx Today, we explored the basics of JavaScript objects – their structure, how to access, update, add, and delete properties, and how to loop through keys. Objects are a powerful way to organize data and model real-world entities in JavaScript. #JavaScript #WebDevelopment #Coding #Programming #LearnJavaScript #TechTips Chai Aur Code Hitesh Choudhary Jay Kadlag Akash Kadlag Piyush Garg

Today I explored one of the most fundamental concepts in programming Classes and Objects, and how they differ between C++ and JavaScript. At first, both looked similar on the surface, but as I went deeper, I realized how different their core concepts actually are. In C++, everything revolves around strict class-based structure with strong typing and clear rules. It feels powerful and controlled. On the other hand, JavaScript is much more flexible. What surprised me the most is that JavaScript is actually prototype-based, and classes are just syntactic sugar over prototypes. This completely changed the way I look at JS. I also learned: How objects are created and used in both languages The difference in syntax and behavior Why JavaScript is more dynamic compared to C++ How concepts like inheritance and encapsulation work differently #javascript #cpp #programming #webdevelopment #learning #developers #codingjourney

While learning JavaScript, I noticed something interesting. Many beginners struggle with arrays. Not because arrays are difficult… But because they’re often explained in a complicated way. So I decided to write a simple beginner-friendly blog explaining: • What arrays are • Why we use them in JavaScript • How to create and access elements • Updating values and basic looping If you're starting your JavaScript journey, this might help you understand arrays more clearly. You can read it here: https://lnkd.in/giEq-xcB Also a big thanks to Hitesh Choudhary sir and Piyush Garg sir I'm learning a lot under his guidance and it has helped me understand programming concepts much better.
