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

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

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

🧠 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 9/30 Functions, Parameters, and Return Values in JavaScript Functions in JavaScript are reusable blocks of code designed to perform specific tasks. They help improve organization, reduce repetition, and make programs easier to maintain. A function can receive Parameters, which act like placeholders for values that are passed in when the function is called. These parameters allow the function to work with dynamic input. After processing the input, a function can provide an output using the return statement. The returned value can then be stored, displayed, or used in further calculations. Together, functions, parameters, and return values make JavaScript logic flexible, reusable, and efficient. #M4ACELearningChallenge #QualityAssurance #AutomationTesting #JavaScript #LearningInPublic

JavaScript tricks I use all the time 👇 Save this 📌 ✅ Optional chaining user?.profile?.name ✅ Nullish coalescing const value = input ?? "default" ✅ Remove duplicates const unique = [...new Set(arr)] ✅ Short condition isLoggedIn && doSomething() ✅ Object destructuring const { name, age } = user 💡 Small JS tricks = cleaner + faster code What’s one JS trick you use daily? #JavaScript #TypeScript #Developers #WebDevelopment #Coding
