Mastering a language through hands-on coding

Sharing beginner-friendly notes on Asynchronous JavaScript ⚡ Concepts like Callbacks, Promises, and async/await can feel confusing at first, so I tried to break them down in the simplest way possible focusing on how JavaScript handles tasks like API calls, timers, and other async operations. Just practical explanations without unnecessary complexity. Feedback and suggestions are welcome! #JavaScript #Coding #Learning #Programming

Mastering 'this' in JavaScript: A Comprehensive Guide to Context The 'this' keyword in JavaScript is notorious for its complexity and the confusion it often causes. This tutorial demystifies 'this', exploring its various contexts, common pitfalls, and how to control its value using 'call', 'apply', and 'bind' for robust application development.

Mastering JavaScript Closures: A Comprehensive Guide with Practical Examples JavaScript closures are a fundamental concept that allows a function to remember and access its lexical scope even when it's executed outside that scope. This tutorial demystifies closures, explaining their mechanics, practical applications, and how they empower powerful design patterns in your JavaScript code.

LeetCode Day 1 : Problem 2 (28 - Remove Element) Just solved my second LeetCode problem. It was "Remove Element" , sounds straightforward, right? But here's what I actually learned: Using .filter() creates a brand new array. It can never modify the original, doesn't matter how you use it. LeetCode checks the original, so it saw nothing changed. Reassigning an array (nums = nums.filter(...)) is not the same as modifying it. Same trap as Problem 1, and I fell for it again. The fix? Two Pointer pattern, one pointer reads every element, another only moves when a valid element is found. No new array created, original gets modified directly. Two problems. Same core lesson showing up again, never create a new array when LeetCode asks for in-place changes. The real lesson? Some bugs don't show up in your own tests. Always ask yourself "am I modifying the original or just creating something new?". #DSA #LeetCode #JavaScript #CodingJourney #Programming

Many beginners in JavaScript get confused between null and undefined, but the difference is actually simple. When a variable is declared but not assigned any value, JavaScript automatically gives it the value undefined. This means the variable exists, but it hasn't been initialized yet. On the other hand, null is a value that is intentionally assigned by the developer to indicate that the variable should contain no value. In simple terms: undefined → variable exists but no value has been assigned yet. null → developer deliberately sets the variable as empty. Pro Tip: Use null when you intentionally want a variable to be empty. If you just declare a variable without assigning anything, it will automatically be undefined. #JavaScript #WebDevelopment #FrontendDevelopment #CodingTips #LearnToCode #Programming #SoftwareDevelopment #Developers #TechLearning #CodingCommunity #100DaysOfCode #JavaScriptTips #CodeNewbie #WebDev

Instead of just using .map(), I tried implementing it myself using Array.prototype polyfills to understand how it actually works internally. The idea is simple: Loop through the array Run a callback on each element Store the returned value in a new array Return the new array at the end Small exercise, but it really helps understand what JavaScript is doing behind the scenes when we call built in methods. Sometimes writing things from scratch teaches more than just using the method.
