Day 2/100 of JavaScript 🚀 Today’s Topic: "let", "const", "var", hoisting and TDZ. "var", "let", and "const" are used to declare variables, but they differ in scope and initialization behavior - "var" is function-scoped and during the creation phase it gets initialized with "undefined", so it can be accessed before assignment. - "let" and "const" are block-scoped and are registered in memory during creation, but not initialized immediately. This leads to TDZ (Temporal Dead Zone) a phase where the variable exists in memory but remains uninitialized and cannot be accessed. Accessing "let" or "const" variables before initialization results in a ReferenceError. - "const" must be initialized at declaration and cannot be reassigned. - "let" allows reassignment but not redeclaration in the same scope. These differences make "let" and "const" more predictable and safer compared to "var". #Day2 #JavaScript #100DaysOfCode

JavaScript performance tip: Use const and let instead of var. Why? → Block scoping prevents bugs → const signals immutability → Better for JS engines to optimize Small syntax change. Big impact on code quality. #JavaScript #BestPractices #Performance

🚀 Understanding Template Literals in JavaScript 📖 Read full guide: https://lnkd.in/ghJ6jZRm While working with JavaScript, I explored how Template Literals simplify string handling and improve code readability. 🔍 Old way (messy): "Hello " + name + "!" ✨ New way (clean): Hello ${name}! 💡 Key Benefits: ✔ Easy variable embedding ✔ Multi-line strings ✔ Cleaner, more readable code Small feature, but a big impact in modern JavaScript 🚀 #JavaScript #WebDevelopment #Coding #FrontendDevelopment #LearningJourney #CleanCode

🚀 Day 17/30 – slice() vs splice() in JavaScript These two methods look similar but behave very differently 👇 🔹 slice() Returns a new array Does NOT modify original array Used to extract elements 🔹 splice() Modifies the original array Can add/remove elements Used for updating the array 💡 In simple terms: 👉 slice = copy 👉 splice = change learn with w3schools.com #Day17 #FrontendDeveloper #JavaScript #InterviewPreparation #WebDevelopment #30DaysChallenge JavaScript Mastery

JavaScript becomes a different language the moment you realize this: 👉 Functions are not just reusable blocks… they are values. And once you understand that, concepts like callbacks and higher-order functions stop feeling confusing and start feeling natural. In this video, I’ve broken it down step by step: How values behave in JavaScript How objects behave Why functions behave the same way (and why that matters) From there, everything builds logically: ✔ Passing functions as arguments ✔ Returning functions from functions ✔ What exactly a callback is ✔ What a higher-order function is ✔ How this leads to more flexible and reusable code No jargon. No unnecessary complexity. Just a clear, practical approach to a core JavaScript concept. 🎥 Watch here: https://lnkd.in/gM8ibZ6M This is Part 1 — next, we’ll explore how this shows up in real code with: setTimeout, forEach, map, filter #JavaScript #WebDevelopment #FrontendDevelopment #Programming #Coding #LearnToCode #JavaScriptDeveloper #SoftwareDevelopment #Developers #CodingJourney #TechEducation #Hosiyar #JS

🧠 Day 3 of 21 days challenge JavaScript Event Loop 🤯 Event Loop is a mechanism in JavaScript that handles execution of asynchronous code. It continuously checks the call stack and callback queue. If the stack is empty, it moves tasks from the queue to the stack for execution. For example :- console.log("Start"); console.log("End"); console.log("Timeout"); Wait… why this order? Because JavaScript doesn’t run everything instantly. It uses: • Call Stack • Web APIs • Callback Queue Event Loop decides what runs next. 💤For easy understanding :- Event Loop = decides execution order Sync code runs first Async code waits in queue Then runs after the stack is empty 👉 That’s why “Timeout” runs last This changed how I understand async code 🚀 #JavaScript #EventLoop #Async
