Learned object literals in JavaScript for #100DaysOfCode

JavaScript Quirks Every Developer Should Know Understanding these "funny" behaviors isn't just entertaining it's essential for writing better code: - - Why [] == ![] is true (type coercion) - Why 0.1 + 0.2 ≠ 0.3 (floating-point precision) - Why sort() doesn't work as expected (alphabetical default) These quirks teach us valuable lessons about JavaScript's underlying mechanics.

Day 26 – Understanding Scope, Closure & Higher-Order Functions in JavaScript Today I learned about three powerful concepts in JavaScript: Scope, Closure, and Higher-Order Functions. These concepts helped me understand how data access and function behavior actually work behind the scenes. The lecture was deeply insightful and covered ideas that are rarely explained this clearly. Thanks to Rohit Negi for the guidance. #coderArmy #JavaScript #WebDevelopment #Frontend #LearningInPublic #Programming #tech #coding #GrowthJourney

Every JavaScript developer has hit that confusing moment when var starts acting like it has a mind of its own 😅 I still remember spending hours debugging a scope issue… only to find out that var is function-scoped, while let and const are block-scoped. That’s exactly what we break down in our new Instagram video a quick visual guide to mastering var, let, and const, so you’ll never get caught off guard again. 📹 Check out the full video on our Instagram-> link in the comments 👇 #JavaScript #WebDevelopment #CodingTips #LearnToCode #FrontendDevelopment #Programming #TechEducation

📘 Chapter 15: Arrays in JavaScript 💻 In this chapter, we explore one of the most essential concepts in JavaScript — the Array 🔢 Arrays allow us to store and manage multiple values in a single variable — making our code cleaner, faster, and more dynamic. ✨ What You’ll Learn: ✅ How to create and access arrays ✅ Add or remove elements with .push(), .pop(), .shift(), .unshift() ✅ Find the length of an array ✅ Loop through arrays using for and forEach() 🚀 Keep learning, keep coding! #JavaScript #WebDevelopment #Coding #Programming #FrontendDevelopment #LearnToCode #100DaysOfCode #CodeNewbie #SoftwareEngineer #Developers #TechCommunity #ArrayInJavaScript #WebDevJourney #CodingLife #JSRoadmap #FullStackDevelopment #TechLearning

🚀 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

Just published a beginner-friendly guide to understanding function binding in JavaScript! If you've ever wondered why `this` becomes undefined in callbacks, this article breaks it down with simple examples. Perfect for developers learning JavaScript or anyone who needs a refresher on bind() 💻 https://lnkd.in/dmAU3Rhc #JavaScript #WebDevelopment #Programming #Coding

Day 3 – JavaScript Loops Practice In this task, I practiced different types of JavaScript loops — for, while, do...while, and for...of — to understand how iteration works in programming. I applied loops to solve small problems like counting numbers, iterating over arrays, and displaying patterns in the console. This practice improved my logic-building skills, debugging techniques, and understanding of flow control in JavaScript. Key Learning Areas: Difference between for, while, and do...while loops Using loops with arrays and objects Avoiding infinite loops and understanding loop conditions Real-time testing using console.log() #JavaScript #WebDevelopment #FrontendLearning #CodingChallenge #Loops #CodingJourney #WomenInTech #100DaysOfCode

Day 9 of #30DaysOfJavaScript on LeetCode Today's challenge: 2703 — Return Length of Arguments Passed The task was to write a function that returns the number of arguments passed to it — a simple yet elegant problem to explore rest parameters in JavaScript. Here’s my solution 👇 var argumentsLength = function(...args) { return args.length; }; It’s a short problem but a great reminder that even small concepts like this are essential for mastering function flexibility in JavaScript!

Day 6 of #30DaysOfJavaScript: Unlocking the Power of Array Reduction by Building My Own! 🚀 Today’s challenge took me under the hood of one of JavaScript’s most versatile methods—the .reduce() function. Instead of relying on the built-in version, I crafted a custom reducer that processes an array sequentially to accumulate a final result from an initial value. Here’s a glimpse of the solution I created: What stood out today: The elegance of breaking down complex operations into simpler, reusable steps using higher-order functions. Deepened my understanding of how accumulator patterns work in JavaScript and other programming languages. A fresh appreciation for common built-in functions that hide these powerful mechanics behind simple calls. This hands-on experience is a big step forward in mastering JavaScript fundamentals and improving my problem-solving skills.
