Debugging Tricks for Frontend Developers: CSS Border and Console Log

💻 JavaScript Beginner Level Practice – Find Largest Number in an Array Today I practiced a simple JavaScript program to find the largest number in an array. function findLargest(arr){ return Math.max(...arr); } console.log(findLargest([1, 5, 3, 9])); 📌 Output: 9 💡 Explanation: This program finds the largest number in an array using "Math.max()" and the spread operator ("..."). #JavaScript #BeginnerLevel #CodingPractice #WebDevelopment #Learning

Today I learned about Synchronous vs Asynchronous JavaScript! Synchronous: Executes line by line, one after another. Asynchronous: Executes without waiting, allowing multiple tasks to run concurrently (like API calls or timers). Example of asynchronous code: console.log("Start"); setTimeout(() => { console.log("After 2 seconds"); }, 2000); console.log("End"); Output: Start → End → After 2 seconds Understanding this helps me see how JavaScript handles tasks efficiently and keeps web apps fast and responsive. #JavaScript #Coding #WebDevelopment #AsyncVsSync #Learning #Programming

Day 5 of Learning JavaScript 🚀 Today I learned about if / else statements. They allow programs to make decisions. Example: if (age >= 18) { console.log("You can vote") } Programming is really about solving problems using logic. #javascript #frontenddeveloper

Async JavaScript is easier to understand when you stop thinking about “parallel code.” JavaScript still runs on a single main thread. What makes it feel non-blocking is the event loop, callback queue, and browser/runtime APIs working together. That is why setTimeout, fetch, and promises do not pause everything else. The big idea: async code gets scheduled first, then runs when the stack is ready. This infographic breaks that flow into the exact pieces that matter.

How TypeScript Compiles Your Code – Step by Step! Ever wondered what happens behind the scenes when you run tsc? TypeScript does a lot more than just adding types to JavaScript. It has a 5-stage compiler workflow that ensures your code is safe, structured, and ready to run. In this carousel, we’ll break down each stage: 1️⃣ Lexer – Converts your code into tokens 2️⃣ Parser – Builds the Abstract Syntax Tree (AST) 3️⃣ Binder – Tracks symbols, scopes, and flow nodes 4️⃣ Checker – Performs syntax and type checking 5️⃣ Emitter – Generates .js, .d.ts, and .map files Swipe through to see each stage visually, understand how TypeScript works under the hood, and get a glimpse of why it’s so powerful for developers! 💻 #TypeScript #WebDevelopment #Frontend #Programming #Developers #CodingTips #JavaScript

In this video, you’ll learn JavaScript Object-Oriented Programming (OOP) from scratch. We’ll cover everything you need to understand how JS objects, constructors, prototypes, and memory work together. Topics covered in this tutorial: ✅ Objects & Properties – What objects, properties, and methods are in JS ✅ this keyword – How this behaves in method calls vs function calls ✅ Constructor Functions – Instance-specific properties and memory allocation ✅ Prototype – Shared methods, prototype chain, and memory efficiency ✅ Difference between Constructor methods & Prototype methods – When memory is separate vs shared ✅ ES6 Classes (Intro) – Syntactic sugar over constructor + prototype (optional teaser)

Understanding Sets, Maps, and Objects in JavaScript: When and How to Use Each Learn the differences between JavaScript's Set, Map, and plain Object data structures, their performance characteristics, and real‑world use cases. This tutorial walks you through practical examples, best practices, and guidelines for choosing the right structure for your code.

🚀 JavaScript Fundamentals Series — Part 6 Arrays are how JavaScript stores lists of data. Almost every real application uses arrays. This guide explains: • How arrays work internally • Accessing and updating values • Looping through arrays • Common array mistakes If you understand arrays well, working with data becomes much easier.

Day 2- of Leetcode 30 days of javascript. Problem 2620 The problem statement was to return a function inside a parent function, and when the parent function is called, it should return in subsequent ascending +1 result. i,e n, n+1, n+2 for any value of n. This problem was based on closures and lexical scope of higher ordered function. There are many approach for this problem but I tried by setting a counter n - 1 and then incrementing it by 1, ie counter += 1. I am open to advice and please comment on how can I improve. #Leetcode #coding #javascript #Logic #growth #programming #higherorderfunction #closures #lexicalscope #scope
