Understanding JavaScript Hoisting Basics

🚀 Day 5/21 – JavaScript DOM Project Built a Random Quote Generator using JavaScript. Live Link: 🛠 Features implemented: ✅ Displays a random motivational quote ✅ Generates new quote on button click ✅ Uses JavaScript arrays and Math.random() ✅ Dynamic DOM updates 💡 Key Learning: Learned how to generate random values and update UI dynamically using DOM manipulation. #Day5 #JavaScript #DOM #FrontendDevelopment #LearnInPublic

🚀 30 Days of JavaScript – Day 10 Today I built a small logical puzzle game called Bulls & Cows. The program generates a secret number and the player must guess it. After each guess, the program gives hints using Bulls (correct digit & position) and Cows (correct digit but wrong position). 🧠 Concepts Used: • loops • string indexing • conditional logic • problem-solving approach 🎥 Demo below 👇 Full source code in the comments. #JavaScript #CodingChallenge #ProblemSolving #WebDevelopment #LearningJavaScript

💡 JavaScript Tip for Developers One of the most common sources of confusion in JavaScript is the difference between == and ===. == performs type coercion, meaning it converts values before comparing. === performs strict comparison, checking both value and type. Example: 0 == false → true 0 === false → false Understanding this difference helps avoid hidden bugs and unexpected behavior in applications. 🎥 I created a 3-minute video explaining the comparison clearly with examples. https://lnkd.in/gQpg2aGp Watch it and strengthen your JavaScript fundamentals. #JavaScript #Programming #WebDevelopment #Frontend #CodingTips

💡 Built a simple interactive Counter using JavaScript! Features include: Increment & Decrement Reset Save & Load A small project, created for JavaScript practice, and it helped me strengthen my concept in DOM manipulation, event handling, and local storage. #JavaScript #WebDevelopment #Coding #Projects #JSPractice

📘 JavaScript Event Loop – Simple Explanation First, JavaScript runs synchronous code (Call Stack). Then it executes Microtasks (like Promises). After that, Macrotasks (like setTimeout) are executed. 👉 That’s why the output is: 1 → 4 → 3 → 2 Today I understood the Event Loop concept clearly 💡 #JavaScript #WebDevelopment #Learning #CodingJourney

While revisiting JavaScript fundamentals, I had a small but interesting realization. When we do something like: "hello world".toUpperCase() we are calling a method on a primitive value. But primitives don’t actually have methods. Behind the scenes, JavaScript temporarily boxes the primitive into its object wrapper (like String) so the method can run, and then discards it. Small detail, but it explains why methods like toUpperCase() work on strings without us ever creating new String(). Sometimes revisiting the basics reveals the most elegant parts of JavaScript. #JavaScript #WebDevelopment #Programming #JSFundamentals

💡 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

You can now render videos from your Boring JavaScript projects with Pellicule. Just install pellicule and create a assets/js/videos/Demo.vue Then run `npx pellicule Demo.vue`, done. Learn more: https://lnkd.in/dZQNH5wn P.S: Video was created 100% by prompting Claude Code using the Pellicule Skills

I learned about scope in JavaScript. There are mainly three types of scope: global scope, function scope, and block scope. Variables declared in the global scope can be accessed from anywhere. var does not maintain block scope, but let and const do. If a variable is declared with var inside a block, it can still be accessed from outside the block. But when let or const is declared inside a block, it cannot be accessed outside of that block. However, var, let, and const all follow function scope. In the case of function scope, variables declared with var, let, or const inside a function cannot be accessed from outside the function. Understanding scope is very important for writing clean and predictable code. #JavaScript #Scope #ProgrammingBasics #WebDevelopment #LearningJourney

🚀 30 Days of JavaScript – Day 4 Continuing my journey to improve JavaScript logical thinking by building small programs every day. 💡 Today’s Program: Vowel Identifier & Replacement This program: i) Takes a name as input ii) Identifies vowels (a, e, i, o, u) iii) Replaces vowels with * iv) Counts the total number of vowels in the name 🧠 Concepts Used: prompt() for user input for loop for iteration toLowerCase() for case handling includes() method Conditional logic (if / else) Example: Input → john Output → j*hn Total Vowels → 1 🎥 Demo below 👇 Full source code in the first comment. #JavaScript #WebDevelopment #CodingJourney #ProblemSolving #LearningJavaScript #30DaysOfCode
