🆕 NEW BLOG! 🆕 🅰️ Modern Angular is easier than React. Here’s why. In this in-depth and neutral analysis, Riccardo Degni explores how modern Angular has evolved with Signals, zoneless rendering, and standalone components to deliver a simpler, more predictable developer experience, especially at scale. 👉 Read the full article on our website : https://lnkd.in/dnfRcypm #Angular #JavaScript #FrontendDevelopment #DeveloperExperience #iJSCon #WebDevelopment

Today I spent time deeply understanding JavaScript closures and it turned out to be really interesting. Here are a few key takeaways: 1. An inner function can access variables from its outer function 2. Even after the outer function has finished execution, the inner function still holds a reference to those variables 3. If closures are not used properly, they can lead to memory leaks and performance issues, especially under heavy load #JavaScript #Closures #FrontendDevelopment #LearningInPublic #WebDevelopment

https://lnkd.in/diyD-KU3 slice vs splice in JavaScript — a small concept that makes a big difference. Understanding which array methods mutate data and which don’t is crucial for writing predictable and bug-free code, especially in frontend frameworks. Sharing a quick visual breakdown for anyone revising JavaScript fundamentals. Which array method confused you the most when you started? #JavaScriptDevelopers #FrontendDevelopment #ProgrammingBasics #DevelopersOfLinkedIn #ContinuousLearning

🟢 Day 17 / 100 – 📌JavaScript Practice 🚀 ✅ Practiced nested arrays using a Tic-Tac-Toe board today. ✅Explored how indexing works in JavaScript by accessing valid, invalid, and negative indexes through the console. • Learned - Errors and undefined values help in understanding how JavaScript actually behaves under the hood. #Day17 #JavaScript #WebDevelopment #FrontendDevelopment

If you’ve ever wondered why your JavaScript arrays suddenly lag, it usually comes down to how V8 handles them under the hood. I put together a quick breakdown of V8 Element Kinds, the internal states that actually determine your code's speed. Understanding how the engine manages your data is a massive help when you're trying to write truly optimized JS. #v8engine #javascript #nodejs #datastructures #developer #performance

🚨 Quick JavaScript challenge Looks like a simple object method accessing this.name. Nothing fancy. Should work… right? But the output is not what most people expect. Before running it - Ask yourself: 👉 Does an object create scope? 👉 Where does this really come from? 👉 Arrow vs normal function - who controls it? Guess the output 👇 #JavaScript #Frontend #CodingChallenge

⚠️ JavaScript Async Error That Slips Into Production Look at this code: try { setTimeout(() => { throw new Error('Boom'); }, 0); } catch (e) { console.log('Caught'); } Most expect the error to be caught. It won’t be. Async errors don’t bubble to outer try/catch. They live in a different execution context. Handle errors where async code runs. #JavaScript #AsyncJavaScript #ErrorHandling #NodeJS #WebDevelopment #JSConcepts #CleanCode #SoftwareEngineering

Hoisting vs Closures in JavaScript 🚀 Understanding JavaScript fundamentals makes your code predictable and powerful. 🔹 Hoisting moves declarations to the top of their scope (not initializations). 🔹 Closures allow functions to remember and access variables from their outer scope, even after execution. 👉 In short: Hoisting lifts declarations, Closures preserve state. Mastering these concepts helps you write cleaner, bug-free, and more efficient JS code. #JavaScript #WebDevelopment #Frontend #CodingConcepts #JSBasics #LearnJavaScript #Developer
