Practicing JavaScript fundamentals with for…of loops. In this project, I: Printed even and odd numbers from an array Calculated the sum of even and odd numbers Found the total sum of all numbers Determined the highest numbers in even and odd arrays Focused on strengthening logic and DOM manipulation skills. #JavaScript #WebDevelopment #CodingPractice #LearningInPub https://lnkd.in/dbPUv_Ka

JavaScript is FUN.... especially for new programmers! JavaScript allows for nesting functions inside of other functions. It's a neat concept that allows you to write quick and easy helpers that don't expose themselves globally. In many other languages you would just group things like this into their own class. But since JavaScript leans heavily into functional programming... I suppose it needs a way to do similar without creating a class. #javascript

😮Cómo funciona el Try Catch en Javascript try { authenticateUser( ); } catch (error) { console.log('Here is the error message and it will continue running: ', error); } How Try Catch works in Javascript #javascript #desarrolladorweb #webdeveloper #code #programming #frontend

Recently , we learned the basics of functions—how to define them, pass parameters, and return values. Functions help us: ✔ Reuse code ✔ Keep programs organized ✔ Make logic easier to understand Example shown: a simple function that adds two numbers and returns the result. Building strong fundamentals one step at a time 🚀 #JavaScript #ProgrammingBasics #WebDevelopment #LearningToCode

👀 This is literally JavaScript vs TypeScript. BEFORE → JavaScript Works? Yes. Understands it? Nobody. Touch one thing and pray 🙏 AFTER → TypeScript Same code. Same logic. But now every "wire" has a type, a label, and a purpose. Your team can actually read it. Your IDE helps you. Bugs get caught before they hit production. I just migrated my project from JS to TS and this image is the most honest thing I've ever seen 😂 The wires didn't change — the structure did. That's TypeScript. #TypeScript #JavaScript #WebDev #CleanCode #100DaysOfCode #Frontend #Programming #Brototype

Learn how the && (AND) operator works in JavaScript and how short-circuit evaluation can save your code from unnecessary execution. In this tutorial, I demonstrate practical examples showing how && decides whether expressions run, helping you write cleaner and more efficient JavaScript. #JavaScript #LogicalAND #ShortCircuitEvaluation #Development #Developer #Programming #Tutorial #CodingTips #JSBasics #SoftwareEngineering

Real-world logic isn’t binary. The else if statement in JavaScript lets your code handle multiple conditions clearly and efficiently 🧠 More conditions. Better decisions. #JavaScript #ElseIf #ProgrammingLogic #FrontendDeveloper #WebDevelopment #CodingTips
