JavaScript Simon Says Game Built with HTML CSS JavaScript

Practicing and revising my JavaScript concepts by building a Simon Says Game using HTML, CSS, and JavaScript. In this project, the player needs to remember and repeat the sequence generated by the system. Through this, I practiced: • DOM events • Arrays for storing sequences • Game logic implementation • User interaction handling Building small projects is a great way to strengthen concepts. 💻✨ #javascript #webdevelopment #frontend #coding #learningbydoing #project #html #css

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

JavaScript can be surprisingly logical… and surprisingly weird at the same time. 😄 Take a look at these three lines: console.log(true + true); console.log(null + 1); console.log(undefined + 1); Before running them, try guessing the outputs. Here’s what JavaScript actually returns: true + true → 2 null + 1 → 1 undefined + 1 → NaN At first, this felt a little strange to me. But it starts to make sense once you remember how type coercion works in JavaScript. true is treated as 1, so 1 + 1 = 2 null becomes 0, so 0 + 1 = 1 undefined turns into NaN, which leads to NaN Small examples like this are a good reminder that JavaScript quietly converts values behind the scenes. And if you’re not aware of it, the results can feel pretty surprising. The deeper I go into JavaScript, the more I realize that understanding these tiny behaviors makes a huge difference in writing reliable code.

🔹Simon Says Memory Game using JavaScript! I recently built a Simon Says Memory Game using HTML, CSS, and JavaScript as part of strengthening my core JavaScript fundamentals 🎮 How to Play • Click start new to start. • Watch the color sequence carefully. • Click the colors in the exact same order. • Each level adds one new color to the sequence. • You must repeat all previous colors + the new one correctly. One wrong click = Game Over. This project helped me strengthen my understanding of DOM manipulation, event handling, and logic building in JavaScript. 🔗 Play here: https://lnkd.in/gu9FqmKG Comment your highest level below 👇 #JavaScript #WebDevelopment #FrontendDevelopment #LearningByBuilding #HTML #CSS

Just built my first real JavaScript project 🚀 I created a Simon Says Game using HTML, CSS, and JavaScript. 🔹 Features: • Dynamic color sequence generation • Real-time user input validation • Progressive difficulty levels 🔹 What I focused on: • DOM manipulation • Event handling • Structuring game logic This project helped me understand how small UI interactions actually work behind the scenes. 👉 Try it here: https://lnkd.in/gVuXbaAq Would appreciate feedback 🙌 #javascript #webdevelopment #100DaysOfCode #learninginpublic

💡 Debounce vs Throttle in JavaScript – A concept every developer should know! Many developers confuse Debounce and Throttle, but understanding the difference can significantly improve application performance. 🔹 Debounce waits until the user stops triggering an event before executing the function. Perfect for: • Search inputs • Autocomplete • API calls 🔹 Throttle ensures a function runs only once within a fixed time interval. Perfect for: • Scroll events • Resize events • Continuous button clicks ⚡ Choosing the right technique helps reduce unnecessary function calls and improves user experience. 📌 Simple rule: Debounce → Wait for inactivity Throttle → Limit execution frequency #JavaScript #WebDevelopment #FrontendDevelopment #CodingTips #Developer #Programming

⚡ Most JavaScript developers only use a few array methods daily. If you know these well, you can handle most data transformations in frontend code. The big ones: 🔹 map() — transform elements 🔹 filter() — keep items that match a condition 🔹 reduce() — accumulate values into one result 🔹 find() / findIndex() — get the first match 🔹 forEach() — run side effects But there are also some important details developers often miss: ⚠️ Some methods mutate the original array ⚠️ Array.sort() sorts values as strings by default ⚠️ Avoid sparse arrays like new Array(n) ⚠️ ES2023 introduced immutable methods like toSorted(), toReversed(), toSpliced() Another powerful pattern used heavily in modern frontend code: Method chaining Filter → Transform → Return the result. Clean. Functional. Readable. Frontscope breaks this down with interactive explanations and examples.

🌳 Ever wondered how the DOM Garden grows? JavaScript is the gardener! ✂️ element.remove() → Prune dead branches 🌱 element.appendChild() → Plant new leaves 🌿 innerHTML / textContent → Water the content 🎨 classList.add() → Add magical glow The DOM is a living tree — and you control every branch. #WebDev #JavaScript #DOM #Coding #Frontend

⚡ Day 2 – getElementById vs querySelector (Real Difference) Selecting elements is one of the most important parts of DOM manipulation. But knowing the difference between these two methods makes your code cleaner and smarter. 🔹 getElementById() ✔ Selects element by id ✔ Slightly faster (direct lookup) ✔ Returns a single element ✔ ID must be unique 🔹 querySelector() ✔ Uses CSS selectors ✔ Can select id, class, or tag ✔ Returns the first matching element ✔ More flexible 🧠 Key Difference: getElementById() works only with id. querySelector() works with any valid CSS selector. Bonus Tip: Use querySelectorAll() when you need multiple elements (returns a NodeList). Mastering small DOM fundamentals like this makes advanced JavaScript much easier. #JavaScript #WebDevelopment #Frontend #DOM #JSConcepts #Coding #100DaysOfCode

🎮 Built a Classic Game with JavaScript! – Simon Says Excited to share one of my mini projects: the Simon Says Game built using HTML, CSS, and JavaScript. This project helped me understand important concepts like: 🔹 DOM Manipulation 🔹 Event Handling 🔹 Game Logic with JavaScript The game challenges players to remember and repeat an increasing sequence of colors. As the levels increase, the sequence gets harder, making it a fun way to test memory and concentration! 🧠⚡ 👨💻 I’m continuously learning and building small projects to strengthen my web development and problem-solving skills. Along with this, I’m also practicing Data Structures & Algorithms (100+ problems solved) to improve my coding ability. 🔗 Check out the project here: GitHub: https://lnkd.in/dUa7xXBs Live Demo: https://lnkd.in/draRQfyf I’d love to hear your feedback and suggestions! 🚀 #WebDevelopment #JavaScript #HTML #CSS #SimonSaysGame #LearningByBuilding #100DaysOfCode
