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

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

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

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.

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

30 Days JavaScript Challenge: Day 11 ✅ Today’s problem was about memoization , a concept where we store the result of a function call and reuse it when the same inputs come again. The goal was to return a memoized version of a function so that it doesn’t run multiple times for the same inputs and instead returns the cached result. It was interesting to see how this can optimize performance, especially for functions like factorial or fibonacci where repeated calculations can happen. Concepts like these show how small optimizations can make a big difference in real applications. 11 days in focusing on understanding not just how to write code, but how to write it efficiently. 💻🚀 #javascript #leetcode #webdevelopment #frontenddeveloper #codingchallenge #learninginpublic #developers #programming #buildinpublic

🚀 Cloning in JavaScript using `Object.assign()` (Oop Concepts) JavaScript's `Object.assign()` method can be used for shallow copying of objects. It copies the values of all enumerable own properties from one or more source objects to a target object. However, it only performs a shallow copy, so if the object contains nested objects or arrays, changes to those nested structures in the cloned object will affect the original object. Understanding this limitation is crucial for avoiding unintended side effects. #oopconcepts #programming #coding #tech #learning #professional #career #development
