Move zeros to end of array with JavaScript

𝐈𝐧 𝐉𝐚𝐯𝐚𝐒𝐜𝐫𝐢𝐩𝐭, 𝐟𝐮𝐧𝐜𝐭𝐢𝐨𝐧𝐬 𝐚𝐫𝐞 𝐧𝐨𝐭 𝐣𝐮𝐬𝐭 𝐟𝐮𝐧𝐜𝐭𝐢𝐨𝐧𝐬… They’re values. You can: • Pass them as arguments • Return them from other functions • Assign them to variables This is what makes patterns like callbacks, closures, and higher-order functions possible. But many developers use these without fully understanding them. We’ve broken it down with simple examples in our latest blog.

Day 2- of Leetcode 30 days of javascript. Problem 2620 The problem statement was to return a function inside a parent function, and when the parent function is called, it should return in subsequent ascending +1 result. i,e n, n+1, n+2 for any value of n. This problem was based on closures and lexical scope of higher ordered function. There are many approach for this problem but I tried by setting a counter n - 1 and then incrementing it by 1, ie counter += 1. I am open to advice and please comment on how can I improve. #Leetcode #coding #javascript #Logic #growth #programming #higherorderfunction #closures #lexicalscope #scope

In JavaScript, Reference Data Types say: “If you change me… I will change the every refrences of yours. 😏 Sounds dramatic? Look at this 👇 let a = [1, 2, 3, 4]; let b = a; b.pop(); console.log(a); console.log(b); comment down the output?? #javascript #coding #learntocode #programming #datatypes #learninginpublic

🚀 Day 21 - Poll answer & Explanation function sum() {  var i, l, result = 0;  for (i = 0, l = arguments.length; i < l; i++) {  result += arguments[i];  }  return result; } console.log(sum(1, 2, 3)) // 6 Explanation (simple & clear): - "arguments" is an array-like object holding all passed values. - Loop runs from 0 to arguments.length. - Each value is added to "result". - 1 + 2 + 3 = 6 Key Point: - Works without defining parameters explicitly. - "arguments" is NOT a real array (no map/filter).

Revisiting a simple but powerful JavaScript concept today: map() map() allows us to transform each element of an array and return a new array. Example: doubling numbers in an array. Small concepts like these form the foundation of writing cleaner and more functional JavaScript code. #JavaScript #WebDevelopment #FrontendDevelopment #Programming #CodingJourney #LearningInPublic

🚀 Day 22 - Poll answer & Explanation const map = new Map(); map.set("a", 1); map.set("b", 2); const set = new Set([1, 2, 3, 3]); console.log(map.size, set.size); 2 3  Explanation (simple & clear):  - Map stores key-value pairs → "a" and "b" → size = 2  - Set stores only unique values → duplicates removed  - [1, 2, 3, 3] → becomes [1, 2, 3] → size = 3  Key Point:  - Map counts unique keys  - Set automatically removes duplicate values  Output:  2 3 #JavaScript #JSInterview #FrontendDevelopment #WebDevelopment  #CodingChallenge #JSConcepts #Developers #Programming  #TechInterview #LearnJavaScript #100DaysOfCode #CodeNewbie  #SoftwareDevelopment #CodingTips #JSBasics #DevelopersLife

30 Days JavaScript Challenge: Day 18 ✅ Today’s problem was about implementing a debounce function. The idea is simple but very useful delay the execution of a function, and if it gets called again within that delay, cancel the previous call and restart the timer. This concept is widely used in real-world scenarios like: • search input optimization • reducing unnecessary API calls • handling rapid user events It was a great exercise to understand how timers and function control work together in JavaScript. 18 days in getting more comfortable with concepts that are actually used in real applications. 💻🚀 #javascript #leetcode #webdevelopment #frontenddeveloper #codingchallenge #learninginpublic #developers #programming #buildinpublic

Mastering JavaScript Arrays Made Simple! Understanding JavaScript array methods is a game-changer. They help you write cleaner, more efficient code without relying on lengthy loops.

🚀 Day 25 - Poll answer & Explanation console.log([].length);   // 0 console.log([,,,].length);  // 3 Explanation: [] → empty array → no elements → length = 0 [,,,] → 3 empty slots (not values, just positions) JavaScript counts slots, not actual values → length = 3 #JavaScript #JSTricks #JSBasics #JSInterview #FrontendDev #WebDevelopment #Coding #Programming #Developer #CodeNewbie #LearnToCode #TrickyQuestions #InterviewPrep #DevTips #JavaScriptTips
