C++ vs JavaScript Classes and Objects: Key Differences

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 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 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 10 ✅ Today’s problem was about creating a function that can be executed only once. The idea was to wrap a given function in such a way that: • it runs normally the first time • and returns undefined on every call after that It’s a small concept, but very useful in real scenarios where you want to prevent a function from running multiple times (like avoiding duplicate actions). 10 days in , just staying consistent and learning step by step. 💻🚀 #javascript #leetcode #webdevelopment #frontenddeveloper #codingchallenge #learninginpublic #developers #programming #100daysofcode

DAY 7 AS A FRONTEND DEVELOPER I focused on learning about variables in JavaScript. Variables are used to store data so it can be used later in a program. They are one of the most important foundations when learning programming. In JavaScript, there are three ways to declare variables: let : used when the value might change const : used when the value should not change var : the older way of declaring variables I am growing, learning and improving every day. #FrontendDevelopment #Day7 #LearningJourney #20DaysLinkedInChallenge #GirlsInTech9.0 #AfricaAgilityFoundation

Understanding JavaScript Variables Variables are the foundation of programming — they store data that your application can use and modify. 📌 Types of Variables: 🔹 Local Variables Declared inside a function Accessible only within that function 🔹 Global Variables Declared outside functions Accessible from anywhere in the script 💡 Key Insight: Use local variables for better control and avoid unnecessary global variables to prevent conflicts. 👉 How do you manage variable scope in your projects? #JavaScript #WebDevelopment #Frontend #Coding #Developers #Learning #Programming

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

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

𝐃𝐚𝐲 𝟔/𝟏𝟓 𝐨𝐟 𝐦𝐲 𝐉𝐚𝐯𝐚𝐒𝐜𝐫𝐢𝐩𝐭 𝐉𝐨𝐮𝐫𝐧𝐞𝐲 🚀 6 days of consistency. Not perfect… But definitely better than Day 1. 💡 What I learned: Functions in JavaScript How to create and use functions Parameters and return values 🧠 What I understood: Instead of writing the same code again and again… We can use functions to reuse it. For example: If I want to add two numbers multiple times, I don’t need to write the logic again and again. I can just create a function and use it whenever needed. At first, I was confused about how parameters work… But after trying small examples, it became clearer. 📌 My biggest takeaway: Functions make code cleaner, shorter, and easier to manage. Still learning… Still improving… See you on Day 7 🚀 #JavaScript #CodingJourney #LearningInPublic #Day6 #Consistency #WebDevelopment #Programming #Developers
