Mastering JavaScript: padStart() Method for String Formatting

> Day 12/21 : JavaScript Control Flow As part of my 21-Day Full Stack Revision Challenge, today I revised control flow in JavaScript, which helps programs make decisions and repeat tasks. Control flow is important because it allows the program to execute different actions based on conditions. > Topics I Covered If–Else Statements – Used to execute code based on conditions Switch Statements – A cleaner way to handle multiple conditions Loops – Used to repeat a block of code multiple times > Why It Matters Control flow helps developers build logical and dynamic programs by controlling how and when code runs.

🚀 Day 22 of My JavaScript Learning Journey Today I learned how to create Array Prototype Last in JavaScript. This method helps us easily get the last element of an array. If the array is empty, it returns -1. By extending Array.prototype, we can create a custom method that works with any array. ✨ What I learned today: ✅ Understanding Array.prototype ✅ Extending built-in JavaScript objects ✅ Accessing the last element of an array ✅ Writing reusable utility methods Learning about prototypes helps understand how JavaScript objects really work under the hood ⚡ #Day22 #JavaScript #ArrayPrototype #WebDevelopment #CodingJourney #LearningInPublic #coddy

Work in progress 💻 Deep in the code today, building out new functionality for Scrimba Advance JavaScript. Sometimes the best commits are the ones that say "promise" twice because that's exactly what clean, asynchronous code delivers. Those small, focused commits? That's where the real progress happens.

🚀 What I Learned Today – JavaScript Basics Today I revised some important concepts in JavaScript: 🔹 Loops (for, while, do-while, for...of, for...in) 🔹 Infinite loop and why it should be avoided 🔹 Strings and how they store text 🔹 String properties (length, indexing) 🔹 Template literals & string interpolation 🔹 String methods (toUpperCase, trim, slice, replace, etc.) Also understood that strings are immutable in JavaScript. Small steps every day to become a better developer 💻 #JavaScript #WebDevelopment #LearningInPublic #CodingJourney

🚀 30 Days of JavaScript – Day 5 Continuing my journey to improve my JavaScript logical thinking by building small programs every day. 💡 Today’s Program: Reverse a String This program takes a word from the user and reverses it using a loop. 🧠 Concepts Used: • for loop • string indexing • basic string manipulation Example: Input → JavaScript Output → tpircSavaJ 🎥 Demo below 👇 Full source code in the First comment. #JavaScript #CodingJourney #ProblemSolving #WebDevelopment #Learning

Javascript concept: var vs let vs const I used var everywhere when I started learning JavaScript… Everything worked… until it didn’t. var a = 10; let b = 20; const c = 30; Then I learned: var ignores block scope ❌ let respects it ✅ const prevents reassignment 🔒 💡 Now my rule: → Use const by default → Use let only when needed #JavaScript #WebDevelopment #Frontend #Coding

🚀 Day 944 of #1000DaysOfCode ✨ Understanding Temporal Dead Zone in JavaScript JavaScript can sometimes behave in unexpected ways — especially when it comes to variable declarations. In today’s post, I’ve explained the concept of the Temporal Dead Zone (TDZ) in a simple and practical way, so you can understand why accessing variables before declaration can throw errors. The TDZ is the time between when a variable is hoisted and when it is actually initialized. This is why variables declared with `let` and `const` behave differently compared to `var`. Understanding this concept helps you avoid tricky bugs and write more predictable and cleaner code. If you’re working with modern JavaScript, knowing how TDZ works is essential for debugging and writing reliable applications. 👇 Have you ever faced a TDZ-related error without knowing the reason? #Day944 #learningoftheday #1000daysofcodingchallenge #FrontendDevelopment #WebDevelopment #JavaScript #React #Next #CodingCommunity #AsyncJavaScript

just built a digital clock using javascript. sounds simple, but not gonna lie… seeing time update automatically felt cooler than it should have . Finally understanding how javascript actually makes a webpage *do* things instead of just sitting there looking pretty. small project, but big confidence boost. trying to move from “watched tutorial” to “ok wait I can build stuff now”. github link in comments. #buildinpublic #javascript #codingjourney #learning

🚀 30 Days of JavaScript – Day 12 Can you solve these number puzzles? 🤔 Today I built a small JavaScript program that asks 3 number pattern questions and calculates the final score. 🧠 Concepts Used: conditional statements user input with prompt() variables and score tracking 🎥 Demo below 👇 Full source code in the First comment. #JavaScript #CodingChallenge #ProblemSolving #LearningJavaScript #WebDevelopment

Loop Less, Map More: Why Modern JavaScript Means Masterful Array Methods. 🚀 We all know how to write a traditional for loop, but in the modern JS landscape, it's not just about getting the job done—it's about writing clean, readable, and performant code. Understanding built-in array methods like .map(), .filter(), and .reduce() is one of the quickest ways to elevate your codebase. They clearly communicate your intention to other developers and promote data immutability, reducing bugs.
