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

30 Days JavaScript Challenge : Day 17 ✅ Today’s problem was about designing a Time Limited Cache. The idea was to store key-value pairs, but with a twist each key should expire after a certain time. The class needed to support: • setting values with an expiry • retrieving values only if they’re still valid • counting how many keys are currently active This felt closer to a real-world problem, especially how caching systems work with expiration. It was interesting to think about how to manage time, state, and updates together in a clean way. 17 days in learning not just syntax, but how to think through problems. 💻🚀 #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

I just published my first blog on Dev.to! I wrote about the current value of JavaScript in 2026 and why it’s still one of the most important skills for developers. I’m still early in my learning journey, so I’d really appreciate any feedback or suggestions 🙌 Here’s the blog: https://lnkd.in/gqQkh-3a #JavaScript #WebDevelopment #LearningInPublic #Programming

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

🌌 What if JavaScript variables were books in a library? Some books can be rewritten. Some are locked forever. Some are shared by many readers. And some quietly disappear when no one remembers them. That’s surprisingly close to how JavaScript variables and memory actually work. I explored this idea through a short story inspired by The Midnight Library. 📖 Read the blog:https://lnkd.in/g46v5jfp #JavaScript #Programming #LearnInPublic #chaicode Hitesh Choudhary Piyush Garg Akash Kadlag

Understanding the difference between var, let, and const is one of the most important fundamentals in JavaScript. Here’s a quick breakdown: var → function scoped let → block scoped const → block scoped and cannot be reassigned These concepts are essential for writing clean and predictable code. If you're learning JavaScript, make sure you understand this clearly.

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 25 ✅ Today’s problem was about merging two arrays of objects based on a common key (id). Sounds simple at first, but it had a few interesting parts: Handling unique ids Merging objects when ids match Making sure values from the second array override the first Keeping everything sorted It’s actually very close to real-world scenarios like combining data from two APIs or updating existing records with new data. Problems like this make you think more about data handling and structure, not just loops and conditions. Day by day, things are starting to connect better. 🚀 #javascript #leetcode #webdevelopment #frontenddeveloper #codingchallenge #learninginpublic #developers #programming #buildinpublic #JavaScriptMastery

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
