🚀 Advanced JavaScript 👉 This is where most interview questions come from 🧠 1. ES6+ Features (Modern JavaScript) 🔹 Arrow Functions const add = (a, b) => a + b; 🔹 Destructuring const user = { name: "Sid", age: 26 }; const { name, age } = user; 🔹 Spread Operator let arr = [1,2,3]; let newArr = [...arr, 4]; 👉 Makes code clean readable 🔄 2. Array Methods (Very Important 🔥) 🔹 map() 👉 Transform data let nums = [1,2,3]; let result = nums.map(n => n * 2); 🔹 filter() 👉 Filter data let nums = [1,2,3,4]; let even = nums.filter(n => n % 2 === 0); 🔹 reduce() 👉 Aggregate data let nums = [1,2,3]; let sum = nums.reduce((acc, curr) => acc + curr, 0); 🌐 3. Fetch API (Connect to Backend) fetch("https://api.example.com/data") .then(res => res.json()) .then(data => console.log(data)); 👉 Used to get data from APIs 🔥 4. Promises (Core Concept) 👉 Handle async operations let promise = new Promise((resolve, reject) => { resolve("Success"); }); States: • Pending • Resolved • Rejected ⚡ 5. Async / Await (Modern Way) async function getData() { let res = await fetch("url"); let data = await res.json(); console.log(data); } 👉 Cleaner than .then() 🔁 6. Event Loop 👉 JavaScript is single-threaded • Call Stack • Callback Queue • Event Loop 👉 Ensures async code runs smoothly 🎯 Mini Project 👉 Create: • Fetch API data (like users) • Display on webpage 💡 Pro Tips > Focus on: • Promises • Async/Await • Fetch API > Practice real APIs (JSONPlaceholder) Double Tap ❤️ For More

⚡ JavaScript Interview Questions with Answers Q1. What is JavaScript? 👉 JavaScript is a programming language used to add interactivity to web pages (clicks, forms, dynamic updates). Q2. Difference between let, const, and var? - var → function scoped (old, avoid) - let → block scoped (can change value) - const → block scoped (cannot reassign) 💡 Example: let a = 10; a = 20; // allowed const b = 10; // b = 20 ❌ error Q3. What is the DOM? 👉 DOM = Document Object Model It allows JavaScript to access and modify HTML elements Q4. What is an event in JavaScript? 👉 Any user action: - click - input - submit Q5. What is a function? 👉 A reusable block of code function greet() { console.log("Hello"); } Q6. What is a closure? 👉 A function that remembers variables from its outer scope function outer() { let count = 0; return function inner() { count++; console.log(count); }; } Q7. What is hoisting? 👉 Variables & functions are moved to top of scope during execution 💡 Only declaration is hoisted, not value Q8. Difference between == and ===? - == → compares value (loose) - === → compares value + type (strict) 5 == "5" // true 5 === "5" // false Q9. What is an arrow function? 👉 Short syntax for functions const add = (a, b) => a + b; Q10. What is an array? 👉 Collection of values let arr = [1, 2, 3]; Q11. What is a Promise? 👉 Represents a future value (async operation) States: - Pending - Resolved - Rejected Q12. What is async/await? 👉 Cleaner way to handle promises async function getData() { let res = await fetch("url"); } Q13. What is the Event Loop? 👉 Handles asynchronous operations in JavaScript 💡 Ensures non-blocking execution Q14. What is callback function? 👉 Function passed as argument function greet(name, callback) { callback(name); } Q15. What is debouncing? 👉 Limits function execution frequency 💡 Used in: - Search bars - Resize events 🔥 Coding Question Q Reverse a String function reverse(str) { return str.split('').reverse().join(''); } 💡 Pro Tips (From Interview POV) Focus on: - Closures - Promises + Async/Await - DOM - Event Loop Always give real-life examples 🎯 Final Advice 👉 Don’t just read → code every question 👉 Practice on: - LeetCode - HackerRank Double Tap ❤️ For More
