Debounce vs Throttle in JavaScript: Understanding the Difference

If you think semicolons don’t matter in JavaScript…? Click “more” before you scroll ... Skipping semicolons feels harmless… 👀 Until this happens 👇 const arr = [1, 2, 3] (function () { console.log("Hello 👋") })() 👉 Error: arr is not a function 😳 👉 Why? JavaScript thinks you're calling the array as a function Because there’s no semicolon before the IIFE 👉 Fix: const arr = [1, 2, 3]; 👉 Small symbol… big problem 😬 This is due to Automatic Semicolon Insertion (ASI) ⚡ Follow for more simple dev concepts 🚀 #JavaScript #Developers #WebDevelopment #Coding #Debugging #Relatable

setTimeout does nothing inside the JavaScript engine. It's a label. A facade. When you call it, JS hands the work off to a browser feature - the actual timer lives outside JavaScript entirely. The browser runs it independently while JS continues on to the next line. All the features we think of as "JavaScript" - timers, network requests, DOM interactions - are actually browser APIs. JS just has labels that trigger them. This is how JS avoids blocking. It doesn't wait. It delegates. The result comes back later, through a controlled channel called the callback queue. Next: the event loop - the single mechanism that controls when deferred code is allowed back into JavaScript. #JavaScript #WebDevelopment #Programming #SoftwareEngineering

🚀 Just built a simple yet fun game using HTML, CSS & JavaScript! It’s a Bat–Ball–Stump game where the user selects an option and the computer makes a random choice 🎮 👉 Rules are simple: Bat 🆚 Ball → User wins Ball 🆚 Stump → User wins Stump 🆚 Bat → User wins This project helped me understand: ✔️ DOM manipulation ✔️ Event handling ✔️ Logic building Small project, but a big step in my learning journey 💻✨ Would love your feedback! #WebDevelopment #JavaScript #CodingJourney #Projects #FrontendDeveloper

Day 4 — Today was the day the web stopped being static for me. DOM manipulation. Sounds scary. Actually really fun. Built a simple to-do list from scratch — no libraries, no frameworks. Just vanilla JS touching the page directly. The moment I typed something in an input field and saw it appear on screen because of code I wrote... that feeling doesn't get old. Key thing I learned: event delegation. Instead of adding an event listener to every single element, you add one to the parent and let events bubble up. Cleaner and way more efficient. Also — preventDefault() is your best friend in form handling. Took me an embarrassing number of refreshing pages to learn that lesson.

Every function you call in JavaScript gets pushed onto a structure called the call stack. That's how JS knows where to go back. Whatever sits on top of the stack is where execution is right now. When the function returns, it gets popped off - and the item below it is back on top, telling JS exactly where to return to. Without this, calling a function from the middle of another function would leave JS completely lost. There would be no "go back to where you were." One side effect: the call stack has limited space. If a function calls itself infinitely with no stopping condition, you get a stack overflow. The name makes perfect sense once you know what it actually is. Next: JS borrows the browser's timer and network - but the browser doesn't hand results back through the call stack.

JS Pop Quiz: Did we just overwrite the Admin?! Let’s see who really understands JavaScript memory allocation! 👨💻👩💻 Look at the code snippet from @codewithsarir. We have a user1 object. We assign it to user2, and then change user2's role to 'Guest'. Question: What does console.log(user1.role) actually print? A) 'Admin' (Because we only changed user2) B) 'Guest' (Because they share the same reference) C) undefined D) It throws a TypeError Hint: Think about how JavaScript handles Objects versus Primitive types like strings. Does = make a copy, or just point to the same address? 🤔 Drop your guess in the comments before you test it in your IDE! 👇 Hashtags: #JavaScript #CodingQuiz #WebDesign #ProgrammerLife #Developers #LearnToCode #JS #Frontend #creators #codinglife #programmer

Built a little browser game over the weekend using just vanilla JavaScript. No frameworks, no libraries — one HTML file. Move your cursor to destroy enemies, survive boss waves, grab power-ups. Runs at 60fps with particle effects and procedural audio. Sometimes the best way to sharpen your skills is to build something fun.

I built my own mini Tailwind CSS engine using vanilla JavaScript Here’s what it does: • Parses custom utility classes (chai-) • Maps them to CSS properties • Applies styles dynamically via JavaScript • Reacts to DOM changes using MutationObserver This project helped me understand: • How utility-first CSS actually works • DOM traversal and dynamic styling • How reactivity can be implemented without frameworks • The trade-offs between static and runtime styling systems Live Demo 👇 https://lnkd.in/gnM67yiQ Source code 👇 https://lnkd.in/gKVgtZGp #javascript #webdevelopment #frontend #css #tailwindcss #learninginpublic #buildinpublic #developers #programming #100DaysOfCode

Day 5 — #100DaysOfCode Built a Random Color Generator using JavaScript today. ✅ With a simple click, the background color changes dynamically—making the concept of DOM manipulation and event handling more practical and visual. Projects like these make learning more engaging and help connect concepts more clearly. Building, learning, and improving step by step. 🚀 #100DaysOfCode #JavaScript #WebDevelopment #FrontendDevelopment #Projects #Consistency
