The new keyword looks simple… but most people use it without knowing what it actually does 👀 That’s exactly where confusion starts. Why does a function suddenly create objects? Where does this point? And how do methods magically appear? 👉 It’s all because of new. In this blog, I’ve explained: What new actually does behind the scenes How constructor functions create objects How objects link to shared methods (prototype) Why everything breaks without new Kept it simple, with step-by-step explanation and examples ✨ 🔗 Read here: https://lnkd.in/dyZwek-x Would love your feedback 🙌 Next: Constructor Functions or this keyword? #javascript #webdevelopment #programming #coding

this in JavaScript looks simple… until it starts pointing to the wrong thing 😵 Same function, different outputs — just because of how it’s called. So what does this actually mean? 👉 It’s not about where the function is written 👉 It’s about who is calling the function In this blog, I’ve explained: What this really represents this in global context this inside objects and functions How calling context changes everything Kept it simple with clear examples (no unnecessary theory) ✨ 🔗 Read here: https://lnkd.in/dMkPffeA Would appreciate your feedback 🙌 #javascript #webdevelopment #programming #coding

Faced a simple but interesting JavaScript interview question today! 💡 ❓ Find the most frequent character in a string. 👉 The trick? 🔹 Count frequencies and track the maximum while iterating. 🔥 Easy Trick to Remember: 🔹 Use an object → count frequency 🔹 Track max → compare while looping 🔹 No need for extra loops ✅ 🧠 Key Insight: “Count + Compare = Result” — no need for sorting or extra passes. #JavaScript #CodingInterview #DSA #WebDevelopment #Programming #TechSkills #CareerGrowth

Got an interesting JavaScript interview question today! 💡 👉 Remove duplicates from an array without using a third variable. The trick is simple: 🔹 Compare elements and remove duplicates in-place. 👉 How it works: 🔹 Compare each element with next ones 🔹 If duplicate → remove using splice() 🔹 Decrease j to recheck index 🧠 Key Insight: “Compare + Remove + Adjust” — no extra space needed! #JavaScript #CodingInterview #DSA #Programming #WebDevelopment #TechSkills #CareerGrowth

JavaScript gets confusing… until it comes to life. I created this short comic to visualize something many beginners struggle with: 👉 var – flexible, but chaotic 👉 let – controlled flexibility 👉 const – stable and predictable 👉 undefined – the mystery we all run into 👉 function – trying to keep everything running Because learning to code isn’t just about syntax—it’s about understanding behavior. And sometimes the best way to teach that… is to see it play out. “Control the code… or the code controls you.” This is exactly how I approach teaching: Make concepts visual Make them memorable Make them feel real Curious—what’s been your biggest “aha” moment with JavaScript? #JavaScript #LearnToCode #WebDevelopment #Coding #Programming #EdTech #VibeCoding #AIinEducation

Came across a classic JavaScript interview question today! 💡 👉 Find the first repeating character in a string. 🔹 The trick is simple track characters as you iterate and return the first one you’ve already seen. 🧠 Key Insight: “Seen before? Return immediately.” — no need for nested loops or sorting. This approach gives an efficient O(n) solution 🚀 #JavaScript #CodingInterview #DSA #WebDevelopment #Programming #TechSkills #CareerGrowth

Closures look confusing at first, but the core idea is simple: A closure is when a function remembers variables from the scope where it was created, even after that outer function has finished running. That is why closures are so useful for private state, counters, factories, and callbacks. The infographic breaks it down visually: create a variable, return an inner function, and that inner function keeps access to the remembered value. If you understand this, a lot of JavaScript starts making more sense.

Sharing beginner-friendly notes on Object-Oriented Programming (OOP) in JavaScript 🧠 Covered core concepts like Classes, Constructors, Inheritance, Encapsulation, Polymorphism, Getters/Setters, Static methods, and Private fields (#) with clear examples. Also explained how super, instanceof, and prototypes work behind the scenes. A practical guide to understanding how OOP works in modern JavaScript. Feedback and suggestions are welcome! #JavaScript #OOP #Coding #Learning #Programming

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

🚀 Binding 'this' in JavaScript Event Handlers within Classes (Oop Concepts) In JavaScript classes, when using `this` inside event handlers, it's crucial to ensure that `this` refers to the class instance. If not bound correctly, `this` may refer to the global object (window) or be undefined. Common solutions include using `bind(this)` in the constructor, using arrow functions which lexically capture `this`, or using the `addEventListener` method with a bound function. These techniques correctly associate the event handler's `this` context with the object instance. #oopconcepts #programming #coding #tech #learning #professional #career #development
