Optimizing Code for Performance with Modern JavaScript

🔵 𝗝𝗮𝘃𝗮𝗦𝗰𝗿𝗶𝗽𝘁 𝘄𝗮𝘀𝗻’𝘁 𝗲𝗻𝗼𝘂𝗴𝗵 — 𝘀𝗼 𝗧𝘆𝗽𝗲𝗦𝗰𝗿𝗶𝗽𝘁 𝘄𝗮𝘀 𝗰𝗿𝗲𝗮𝘁𝗲𝗱 JavaScript is powerful, but in large applications, it can become hard to manage. That’s where TypeScript comes in. It adds: 📦 static typing 🧠 better code structure ⚠️ early error detection TypeScript helps developers catch mistakes before running the code. That’s why many modern projects use it today.

Just published a new article on writing flexible code without losing type safety with TypeScript generics. A practical guide to building reusable abstractions while keeping strong, predictable types. 💬 Thoughts?

When I started JavaScript… I thought: 👉 “Browser is running my code” Reality 👇 There’s an ENGINE behind everything ⚡ 👉 The V8 Engine That’s when I realized: 💡 Code ≠ Execution 💡 Syntax ≠ Performance 🔥 The real game: Understanding what happens under the hood Since then… I don’t just write JS 👉 I write V8-friendly JS 💬 When did YOU realize this? 👇 #JavaScript #Learning #Developers #V8 #CodingJourney

Javascript concept: var vs let vs const I used var everywhere when I started learning JavaScript… Everything worked… until it didn’t. var a = 10; let b = 20; const c = 30; Then I learned: var ignores block scope ❌ let respects it ✅ const prevents reassignment 🔒 💡 Now my rule: → Use const by default → Use let only when needed #JavaScript #WebDevelopment #Frontend #Coding

I just published a Medium blog on the JavaScript.filter() method. In this guide, I explore how every developer can effectively use this method and highlight its application in sophisticated systems, such as building a React application.

⚡ What if your Node.js script could behave like a real terminal command? Not like this: node script.js But like this: mytool greet Shaheryar Just like git, npm, or docker. The strange part? It only takes one tiny line of code and a small npm trick to turn a normal script into a global CLI command. In my latest article I show how this works — and why many popular developer tools secretly use the same mechanism. 👉 Full article: https://lnkd.in/dGjFAJYc If you could build one custom CLI command for your workflow, what would it be? 👀 #NodeJS #JavaScript #DevTools #CLI #Programming #SoftwareEngineering #Developers

Day 8 of “Js in bits series – (typeof) Key things covered in the article: 🔹 How typeof helps identify different JavaScript datatypes 🔹 What typeof returns for primitives like number, string, boolean, bigint, undefined, and symbol 🔹 Why typeof null returns "object" (a long-standing JavaScript quirk) 🔹 Practical examples of using typeof in real code #javascript #webdevelopment #frontend #softwareengineering #coding #learning

Loop Less, Map More: Why Modern JavaScript Means Masterful Array Methods. 🚀 We all know how to write a traditional for loop, but in the modern JS landscape, it's not just about getting the job done—it's about writing clean, readable, and performant code. Understanding built-in array methods like .map(), .filter(), and .reduce() is one of the quickest ways to elevate your codebase. They clearly communicate your intention to other developers and promote data immutability, reducing bugs.

Work in progress 💻 Deep in the code today, building out new functionality for Scrimba Advance JavaScript. Sometimes the best commits are the ones that say "promise" twice because that's exactly what clean, asynchronous code delivers. Those small, focused commits? That's where the real progress happens.

JavaScript is a single-threaded language, which means it executes one task at a time using the call stack. But it can still handle asynchronous tasks like API calls, timers, and promises. This happens because of the Event Loop. The Event Loop continuously checks if the call stack is empty. When it is empty, it takes tasks from the callback queue and moves them to the stack to be executed. Because of this system, JavaScript can run asynchronous operations without blocking the main thread, which makes web applications faster and more responsive. Learning the Event Loop helped me understand how JavaScript manages asynchronous code behind the scenes. #JavaScript #Coding #EventLoop #async
