JavaScript Event Loop – Quick Example Understanding the Event Loop is important for writing efficient asynchronous JavaScript. Example: console.log("Start") const prom = new Promise((res) => res(true)) setTimeout(() => console.log("setTimeout"), 0) process.nextTick(() => console.log("nextTick")) queueMicrotask(() => console.log("microtask")) console.log(prom) Output order will be: Start Promise { true } nextTick microtask setTimeout Why? Because JavaScript processes tasks in this order: 1. Synchronous code 2. Microtasks (nextTick, Promises, queueMicrotask) 3. Macrotasks (setTimeout, setImmediate) Understanding this helps when debugging async issues in frontend apps. #javascript #webdevelopment #frontend #vuejs #eventloop

🏠 Lexical Scope in JavaScript Think of your code like a house with rooms. 🌍 The whole house = Global Scope 🏠 Each room = A Function 🚪 A room inside another room = Nested Function Now here’s the important rule: 👉 Inner rooms can see outside. 👉 But outside rooms can’t see inside. Let’s understand using the image: 🌍 Global Scope (Outside the house) let hero = "Alice"; 🏠 Outer Function (First room) let spell = "Fire"; 🚪 Inner Function (Room inside room) let mana = 50; console.log(hero); // ✅ Can access (Global) console.log(spell); // ✅ Can access (Outer) console.log(mana); // ✅ Its own variable ✔ Inner function can access: Its own variables Parent function variables Global variables But if the outer function tries this: console.log(mana); // ✖️ Error It fails. Because outer cannot access inner’s variables. 🔑 Simple Rule to Remember: A function can use variables from: 🏠 Its own room ⬆ Parent rooms 🌍 Global But it cannot look inside child rooms. #javascript #typescript #reactjs #nextjs #frontend_developer #react_developer #web_Developer #scope #laxical

Most developers use forEach() and map() interchangeably — but they are NOT the same. ✔ Use forEach() for side effects ✔ Use map() for transformation ✔ Prefer map() when you need a new array Understanding this difference shows strong JavaScript fundamentals. #JavaScript #Frontend #WebDevelopment #CodingInterview #TechInterview

*JavaScript Hoisting Tip* In JavaScript, variables and functions are hoisted to the top of their scope. before code execution. ✔ "var" is hoisted and initialized with **undefined** ✔ "let" and "const" are hoisted but stay in the **Temporal Dead Zone** until declared. # Best practice: Always declare variables at the top of your scope to avoid unexpected bugs. #JavaScript #WebDevelopment #Frontend #CodingTips
