learned about the switch statement in JavaScript. It is used when we need to check multiple conditions. Example: let day = 2; switch(day){ case 1: console.log("Monday"); break; case 2: console.log("Tuesday"); break; default: console.log("Another day"); } Switch statements make code cleaner when handling many conditions. #JavaScript #CodingJourney #FrontendDeveloper

🚀 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

Day 1 — Reverse a String (JavaScript) Problem Write a function that reverses a given string. Example Input: "hello" Output: "olleh" Approach Start from the last character of the string and iterate backwards. Keep adding each character to a new string until the loop finishes. Code function reverseString(str){ let reversed = "" for(let i = str.length - 1; i >= 0; i--){ reversed += str[i] } return reversed } console.log(reverseString("hello")) What I Learned Basic string traversal and how iteration works from the end of a string. #javascript #frontenddeveloper #codingpractice #dsa

🚀 𝗪𝗵𝗼 𝗘𝘅𝗲𝗰𝘂𝘁𝗲𝘀 𝗙𝗶𝗿𝘀𝘁 𝗶𝗻 𝗝𝗮𝘃𝗮𝗦𝗰𝗿𝗶𝗽𝘁? 🚀 I’ve just shared a handy guide—“Who Executes First in JavaScript: Synchronous, Microtasks & Macrotasks”—to help you predict exactly when your code runs and avoid those nagging timing bugs. 𝗠𝗮𝗶𝗻 𝘁𝗮𝗸𝗲𝗮𝘄𝗮𝘆𝘀: - 𝗦𝘆𝗻𝗰 𝗳𝗶𝗿𝘀𝘁: Plain console.log calls run immediately in sequence. - 𝗠𝗶𝗰𝗿𝗼𝘁𝗮𝘀𝗸𝘀 𝗻𝗲𝘅𝘁: Promises (and await continuations) always beat macrotasks. - 𝗠𝗮𝗰𝗿𝗼𝘁𝗮𝘀𝗸𝘀 𝗹𝗮𝘀𝘁: Even setTimeout(..., 0) waits until after all sync and microtasks. Want to see this in action? Check out the slide deck for live code examples—and let me know which timing gotcha has tripped you up the most! #javascript

Javascript concept: == vs === This bug looked harmless… console.log(5 == "5"); // true But in production? It broke logic. console.log(5 === "5"); // false 💡 One habit that saved me: → Always use === #JavaScript #WebDevelopment #Frontend #Coding

🚀 Day 29 - 💡 JavaScript Tricky Question Explanation let a = [1,2,3]; delete a[1]; console.log(a); console.log(a.length); 👉 Output: ``` [1, empty, 3] 3 ``` 👉 Explanation: * `delete` removes the value but does NOT reindex the array * It creates a hole (empty slot) instead of shifting elements * So, `length` remains 3 ⚠️ Use `splice()` if you want to remove and shift elements #JavaScript #WebDevelopment #Frontend #CodingInterview #JSConcepts
