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

30 Days JavaScript Challenge : Day 24 ✅ Today’s problem was about sorting an array using a custom function. Instead of directly sorting values, we use a function fn to decide the order — basically telling JavaScript how to compare elements. At first it feels simple, but it actually shows how powerful sorting can be when you control the logic: Sorting objects based on a property Sorting nested arrays Custom ranking based on conditions It’s one of those concepts that looks basic but is used everywhere in real projects. Slowly getting more clarity on how to write flexible and reusable logic in JavaScript. #javascript #leetcode #webdevelopment #frontenddeveloper #codingchallenge #learninginpublic #developers #programming #buildinpublic

What is ? 🤔 Just a question mark… right? Nope 😏 In JavaScript, this tiny symbol can save your production from crashing 💥 👉 ?. → optional chaining user.profile?.name No crash… just undefined 😌 👉 ?? → nullish coalescing age ?? 18 Only replaces null or undefined Not 0 or false 🔥 👉 ? : → ternary operator isLoggedIn ? "Welcome" : "Login" Short and clean condition 🔥 Rule: ?. → safe access ?? → correct default ? : → quick condition 💬 Question: Which one do you use the most in real projects? 😄 #javascript  #codingtips #programming #developer #100daysofcode

30 Days JavaScript Challenge : Day 20 ✅ Today’s problem was about checking whether a given object or array is empty. At first glance, it looks very simply, but it makes you think about how data structures actually store values whether it’s checking keys in an object or elements in an array. Also tried to think about how this can be done efficiently, even aiming for O(1) time complexity. Problems like these remind me that even basic concepts can have deeper layers when you try to implement them properly. 20 days in consistency is building up, one problem at a time. 💻🚀 #javascript #leetcode #webdevelopment #frontenddeveloper #codingchallenge #learninginpublic #developers #programming #buildinpublic

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
