Higher Order Functions in JavaScript Explained

> Day 12/21 : JavaScript Control Flow As part of my 21-Day Full Stack Revision Challenge, today I revised control flow in JavaScript, which helps programs make decisions and repeat tasks. Control flow is important because it allows the program to execute different actions based on conditions. > Topics I Covered If–Else Statements – Used to execute code based on conditions Switch Statements – A cleaner way to handle multiple conditions Loops – Used to repeat a block of code multiple times > Why It Matters Control flow helps developers build logical and dynamic programs by controlling how and when code runs.

🚀 30 Days of JavaScript – Day 12 Can you solve these number puzzles? 🤔 Today I built a small JavaScript program that asks 3 number pattern questions and calculates the final score. 🧠 Concepts Used: conditional statements user input with prompt() variables and score tracking 🎥 Demo below 👇 Full source code in the First comment. #JavaScript #CodingChallenge #ProblemSolving #LearningJavaScript #WebDevelopment

Day 12 #100DaysOfCode 💻 Today I learned about Synchronous vs Asynchronous JavaScript, especially how setTimeout() and setInterval() work. JavaScript runs code synchronously by default (line by line). But functions like "setTimeout()" run asynchronously, meaning they execute later without blocking the main thread. Example: console.log("1"); setTimeout(() => { console.log("2"); }, 0); console.log("3"); Output: 1 3 2 Even with "0ms", "setTimeout" goes to the callback queue, so the synchronous code runs first. Understanding this concept helped me see how JavaScript handles non-blocking tasks. #JavaScript #AsyncJavaScript #WebDevelopment #CodingJourney #Akbiplob

🚀 Day 39/50 – Scope in JavaScript Today I learned about Scope in JavaScript, which defines where variables can be accessed in a program. 🔹 Scope determines the visibility and accessibility of variables. 📌 Types of Scope in JavaScript 1️⃣ Global Scope – Variables declared outside any function can be accessed anywhere. let name = "Priyanka"; function show() { console.log(name); } show(); 2️⃣ Function Scope – Variables declared inside a function are accessible only within that function. function test() { let msg = "Hello"; console.log(msg); } test(); 3️⃣ Block Scope – Variables declared with let and const inside {} are block-scoped. if(true){ let x = 10; console.log(x); } 4️⃣ Local Scope – Variables declared inside a block or function are local to that area. 💡 Key Learnings: ✅ var → function scoped ✅ let and const → block scoped ✅ Scope helps avoid variable conflicts ✅ Improves code security and readability Thanks for mentors 10000 Coders Raviteja T Abdul Rahman #Day39 #50DaysOfCode #JavaScript #WebDevelopment #FrontendDeveloper #CodingJourney #LearningEveryday

🚀 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 bugs don’t just break the code… they create new dimensions of problems. 😅 Every error feels like a puzzle no one prepared you for. #JavaScript #CodingMemes #DeveloperLife #WebDevelopment

🚀 What I Learned Today – JavaScript Arrays Today I explored Arrays in JavaScript and here are the key takeaways 👇 🔹 Arrays are a collection of items 🔹 They are linear (elements stored sequentially) 🔹 Arrays are mutable (can be changed after creation) 📌 Array Indices Positions of elements in an array (starting from 0) 📌 Looping Through Arrays Used to print or access all elements easily 📌 Useful Array Methods ✔️ push() – add element to end ✔️ pop() – remove element from end ✔️ unshift() – add element to start ✔️ shift() – remove element from start ✔️ toString() – convert array to string ✔️ concat() – merge arrays ✔️ slice() – get part of array (no change to original) ✔️ splice() – modify array (add/remove/replace) 💡 Example: slice(start, end) splice(start, deleteCount, newElement) Learning step by step and building strong fundamentals 💪 #JavaScript #WebDevelopment #CodingJourney #FrontendDevelopment #100DaysOfCode)

🚀 What I Learned Today – JavaScript Basics Today I revised some important concepts in JavaScript: 🔹 Loops (for, while, do-while, for...of, for...in) 🔹 Infinite loop and why it should be avoided 🔹 Strings and how they store text 🔹 String properties (length, indexing) 🔹 Template literals & string interpolation 🔹 String methods (toUpperCase, trim, slice, replace, etc.) Also understood that strings are immutable in JavaScript.

💡 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
