Memoization Challenge: Optimizing Function Performance

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

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 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 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

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

30 Days JavaScript Challenge : Day 26 ✅ Today’s problem was about flattening a multi-dimensional array, but with a twist we were given a depth n and had to flatten only up to that level. Not a full flatten, not a shallow one… somewhere in between. It really makes you think about recursion and depth control: When to go deeper When to stop How to keep track of current depth What I liked is how this problem builds intuition around nested data structures something you see a lot in real apps (APIs, configs, UI trees, etc.). Slowly getting more comfortable with recursion and thinking in layers. #javascript #leetcode #webdevelopment #frontenddeveloper #codingchallenge #learninginpublic #developers #programming #buildinpublic

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.

Recently started learning Go. My current approach: solve the problem in JavaScript first, then implement the same solution in Go. Why? Because it lets me separate algorithmic thinking from learning a new syntax. It’s a simple process, but so far it feels effective: understand the logic first, then strengthen Go through practice. Small steps, but consistent ones. #GoLang #Go #Programming #SoftwareDevelopment #BackendDevelopment #Coding #JavaScript
