JavaScript Datatypes: Exploring Numbers, Infinity, and NaN

💻 Today's Chaicode Class Takeaways We dived into JavaScript Events: Writing Events: Inline, eventName, Event Listeners Event Phases: Bubbling: child → parent Capturing: parent → child Controlling Propagation: stopPropagation() Event Delegation: Handle multiple children with a single parent listener #JavaScript #WebDevelopment #Coding #FrontEnd #EventHandling #Programming #LearnToCode #TechLearning #DeveloperLife #CodeNewbie #Chaicode Hitesh Choudhary Suraj Kumar Jha Hitesh ChoudharySuraj Kumar Jha

In JavaScript, Reference Data Types say: “If you change me… I will change the every refrences of yours. 😏 Sounds dramatic? Look at this 👇 let a = [1, 2, 3, 4]; let b = a; b.pop(); console.log(a); console.log(b); comment down the output?? #javascript #coding #learntocode #programming #datatypes #learninginpublic

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

In my previous post, I shared Method 1 of implementing a simple login and logout system using JavaScript. In the next post, I will share Method 2, where I’ll explain a different approach and also highlight the key differences between both methods. Stay tuned to see how the second method works and how it improves the functionality. Method 2 – Coming Soon. #WebDevelopment #JavaScript #FrontendDevelopment #Programming #Coding #SoftwareDevelopment #WebDeveloper #DeveloperLife #TechCommunity #LearnToCode #CodingJourney #WomenInTech Javeria Naz Dpoxy Logics

Yet it can handle things like: 🌐 network requests ⏳ timers 📦 user interactions The secret is the **Event Loop**. It manages: • Call Stack • Task Queue • Callback execution So while one task runs, others wait in the queue.

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

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

Mastering 'this' in JavaScript: A Comprehensive Guide to Context The 'this' keyword in JavaScript is notorious for its complexity and the confusion it often causes. This tutorial demystifies 'this', exploring its various contexts, common pitfalls, and how to control its value using 'call', 'apply', and 'bind' for robust application development.
