Got a minute for some JavaScript? 🍵 What does this code output? Answers 🔍 >>> - ReferenceError: message is not defined Why? Because let lives only inside the block where it’s created. In this code, message is created inside the *if {}* and *else {}* blocks. When JavaScript reaches *console.log(message)*, it is already outside those blocks, so the variable no longer exists. #javascript #webdevelopment

Got a minute for some JavaScript? 🍒 What does this code output? Answers 🔍 >>> - "Tom says meow" - TypeError: c.createKitten is not a function - "Kitty says meow" Why the TypeError? *createKitten* is a static method - it lives on the *Cat* constructor, not on instances. *c* is an instance, so it cannot access static methods. Only *Cat.createKitten()* works. #javascript #webdevelopment

Today I practiced the difference between map(), filter(), and forEach() in JavaScript. map() creates a new array by transforming each element of the original array. filter() creates a new array with elements that satisfy a specific condition. forEach() simply runs a function for each element and does not return a new array. Understanding these methods makes working with arrays much easier and cleaner. #JavaScript #WebDevelopment #ArrayMethods #LearningJourney

💡 JavaScript Trick Question: 3 + 2 + "7" In JavaScript, the answer is: 👉 "57" 🔍 Why? 🔹 JavaScript follows left-to-right evaluation and uses type coercion. ⚡ Key Insight : 🔹Once a string enters the expression, everything after that becomes a string operation. "In JavaScript, the moment a string joins the party, numbers stop adding and start concatenating." #JavaScript #WebDevelopment #CodingInterview #Frontend #JSConcepts

🚀 JavaScript Fundamentals Series — Part 7 Most developers use arrays every day… But many don't fully understand array methods. This guide explains the most important ones: • map() • filter() • reduce() These methods help you write cleaner and more functional JavaScript. Once you master them, your code becomes much more expressive. Full guide 👇 https://lnkd.in/dZTRRCUx #javascript #webdevelopment #functionalprogramming

🚀 JavaScript Fundamentals Series — Part 5 JavaScript introduced arrow functions to make functions cleaner and shorter. But they also behave differently from normal functions. In this guide I explain: • Arrow function syntax • Implicit return • Why arrow functions don't have their own this • When to use them (and when NOT to) Once you understand this, modern JavaScript becomes much easier to read.
