Tree Shaking vs Rollup: What's the Difference

Six characters that completely changed how we write JavaScript. 👇 If your code is still cluttered with the function keyword, it’s time for an upgrade. Arrow functions () => {} aren't just syntactic sugar; they are the backbone of clean, modern JS. Swipe through the carousel to see: - Why developers prefer them - How they fix the classic this headache - Where they shine the most How often are you using arrow functions in your current projects? #JavaScript #WebDev #CleanCode #Frontend #Coding

💡 One thing I recently learned: Stop hardcoding content. Instead of writing everything in HTML, I started using JSON-driven structure. Why? ✔ Easy to update ✔ Better scalability ✔ Cleaner code Frontend is evolving—and structure matters. #javascript #frontend #webdev

💡 Focused on writing *clean and optimized JavaScript*. ✔ Writing modular, reusable functions instead of large code blocks ✔ Reducing unnecessary DOM manipulation for better performance ✔ Using debounce & throttle to handle real-world user interactions 🚀 What I think clean code is not just about syntax — it's about mindset. Still learning. Still growing. 🤞 #JavaScript #WebDevelopment #CleanCode #Frontend #Performance #DeveloperLife

We all use try...catch in JavaScript. But do we really understand it? 👀 I recently explored some surprising behaviors: finally can override your return 🤯 1. try-catch doesn’t handle async errors ❌ 2. catch is actually optional 😳 These small nuances can save you from production bugs. Wrote a simple and practical breakdown 👇 https://lnkd.in/g7NQJzcT Would love your feedback 🙌 #javascript #webdevelopment #frontend #coding #learninpublic

Scroll events giving you headaches? 😩 There's a better way. The Intersection Observer API lets you detect when elements enter the viewport — no scroll listeners, no layout thrashing, just clean and efficient JS. ⚡ I just published a full breakdown with real code examples, tips, and common mistakes to avoid. 🔧 Read it now 👉 hamidrazadev.com #javascript #webdev #frontend #learntocode #100daysofcode

Why does JavaScript show "undefined"? If you’ve seen this, you’ve already faced Hoisting. I broke it down in the simplest way possible 👇 ✔ JavaScript runs in 2 phases ✔ var is hoisted with undefined ✔ let & const are hoisted but not initialized (TDZ) 💡 Rule: Always declare variables before using them Save this for revision 📌 #javascript #webdevelopment #frontend #coding #reactjs

Day 5 Callback Functions 🔁 Understanding how functions can control the flow of execution is a game changer in JavaScript. Callbacks help us handle tasks at the right time, especially when working with async operations. 💡 Simple idea: “Do this task, and when it’s done, call another function.” Question: Where have you used callbacks in your projects? 👇 #JavaScript #WebDevelopment #Frontend #CodingJourney #LearnToCode

Just published a new blog on Array Flattening in JavaScript 🚀 If you've ever worked with nested arrays and wondered how to convert them into a single-level array efficiently, this one's for you. I’ve covered different approaches—from built-in methods to custom logic—with clear examples. 🔗 Read here: https://lnkd.in/dVgZ_SUT Would love to hear your thoughts and how you usually handle nested arrays in your projects! #JavaScript #WebDevelopment #Coding #Frontend #Developers #100DaysOfCode
