Part 2 of using reduce() method in JavaScript. Let’s talk about getting the product of numbers in JavaScript Arrays. #JavaScript #WebDevelopment #CodingTips #LearnToCode #softwaredeveloper

Javascript Scopes in 30 seconds. Many bugs in JavaScript come from misunderstanding scope. Scope decides where variables live and who can access them. var → function scoped let / const → block scoped #JavaScript #CodingJourney

Exploring the power of Functions in JavaScript 💻 Functions allow developers to break large programs into smaller reusable blocks, making code cleaner and easier to manage. From function declarations to arrow functions, mastering them is key to writing efficient JavaScript code. #JavaScript #CodingJourney #WebDevelopment #LearnToCode #Pyspiders

Got a minute for some JavaScript? 😚 What does this code output? Answer 🔍 >>> undefined I don’t really like questions where you just have to be attentive, but I think this is something worth paying attention to. To get the number of entries in a *Map*, you use the *.size* property, not *.length* like in arrays. In short: .length --> Arrays, Strings, function parameters .size --> Map, Set #javascript #webdevelopment

📘 JavaScript Event Loop – Simple Explanation First, JavaScript runs synchronous code (Call Stack). Then it executes Microtasks (like Promises). After that, Macrotasks (like setTimeout) are executed. 👉 That’s why the output is: 1 → 4 → 3 → 2 Today I understood the Event Loop concept clearly 💡 #JavaScript #WebDevelopment #Learning #CodingJourney

I focused on understanding null and undefined in JavaScript. null usually means a value is intentionally set to “no value.” undefined means a value is not assigned or not available for some reason. This small difference is very important when writing clean and bug-free code.

Today’s JavaScript session was very insightful. I learned about the this keyword in depth and explored important concepts like call(), bind(), apply(), and factory functions. Understanding how this works in different contexts has given me much more clarity and confidence in writing better JavaScript code.

Day 38/100 🚀 Still on JavaScript objects — practicing creating objects, accessing properties, and understanding how objects behave differently from primitive data types. #100DaysOfCode #JavaScript #WebDev

If you think reduce() is only for summing numbers… you’re limiting yourself. Here’s what you don’t know about the JavaScript reduce method (Part 1). 👇 Have you ever used reduce in a real project? #JavaScript #WebDevelopment #CodingTips #LearnToCode #SoftwareDeveloper

Day 32 of #100DaysOfCode Today I learned one of the most important JavaScript topics for full-stack development: Functions. Covered: • Function declaration & expression • Parameters vs arguments • Return statement • Arrow functions • Basic callback functions Functions are everywhere — from frontend logic to backend APIs. #FullStackDevelopment #JavaScript #LearningInPublic #WebDevelopment
