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

Built a fully functional Smart Event Dashboard from scratch using pure HTML, CSS & JS — no frameworks, no libraries. Just clean code and creativity. 🎨💻 The best way to learn is to build. What are you building this week? 👇 #JavaScript #WebDev #100DaysOfCode #FrontendDeveloper #CodingJourney

Practicing JavaScript Strings with a simple hands-on project 💻 Built a couple of small projects,out of them one is here 🔹 Convert text to UPPERCASE & lowercase 🔹 Remove extra spaces 🔹 Replace specific words dynamically This helped me improve my understanding of: ✔ String methods ✔ Regular expressions for cleaning text ✔ DOM manipulation & event handling #JavaScript #WebDevelopment #Frontend #CodingPractice #LearningJourney

🧠 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

🚀 Day 955 of #1000DaysOfCode ✨ How JavaScript Event Loop Works Behind the Curtains JavaScript looks simple on the surface — but under the hood, a lot is happening to make async code work smoothly. In today’s post, I’ve explained how the JavaScript Event Loop actually works behind the scenes, so you can understand how tasks are executed, queued, and prioritized. From the call stack to the callback queue and microtask queue, this concept explains why some functions run before others — even when the code looks sequential. Understanding the event loop helps you debug tricky async issues, avoid unexpected behavior, and write more predictable code. If you’re working with promises, async/await, or APIs, this is one of those concepts you must truly understand. 👇 What part of the event loop confuses you the most — call stack, microtasks, or callbacks? #Day955 #learningoftheday #1000daysofcodingchallenge #FrontendDevelopment #WebDevelopment #JavaScript #React #CodingCommunity #AsyncJavaScript

Built-in vs Manual Flattening in JavaScript Stop writing custom logic to flatten arrays in JavaScript. There’s already a built-in method for it: flat(Infinity) It flattens nested arrays of any depth into a single-level array, no loops, no recursion. Example: [1, [2, [3, [4]]]].flat(Infinity) // → [1, 2, 3, 4] Sometimes the simplest solutions are already part of the language. Knowing your standard library can save you more time than any framework.

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
