🚀 Smart Music Recommendation System 🚀 I'm excited to share my new Machine Learning project. This is a full-stack application where the magic happens in the backend with Python, using Pandas for data crunching and Scikit-learn to build the recommendation model and other necessary modules for ML. The frontend is a sleek, custom-built interface with HTML, CSS, and JavaScript, which seamlessly connects to my ML engine through a RESTful API. It's been an incredible journey building this from dataset analysis to a working web app. This is just the first version  stay tuned for upgrades.       Smart Music Recommendation System @codewithmemo @codewithmemo

✅ 20 JavaScript Interview Questions 1. What are the different data types in JavaScript • String, Number, Boolean, Undefined, Null, Object, Symbol, BigInt Use typeof to check a variable’s type. 2. What is the difference between == and === • == compares values with type coercion • === compares both value and type (strict equality) 3. What is hoisting in JavaScript Variables and function declarations are moved to the top of their scope before execution. Only declarations are hoisted, not initializations. 4. What is a closure A function that remembers variables from its outer scope even after the outer function has finished executing. Example:

function outer() {
  let count = 0;
  return function inner() {
    count++;
    console.log(count);
  };
}
const counter = outer();
counter(); // 1

5. What is the difference between var, let, and const • var: function-scoped, can be re-declared • let: block-scoped, can be updated • const: block-scoped, cannot be re-assigned 6. What is event delegation Using a single event listener on a parent element to handle events from its child elements using event.target. 7. What is the use of promises in JavaScript Handle asynchronous operations. States: pending, fulfilled, rejected Example:

fetch(url)
.then(res => res.json())
.catch(err => console.error(err));

8. What is async/await Syntactic sugar over promises for cleaner async code Example:

async function getData() {
  const res = await fetch(url);
  const data = await res.json();
  console.log(data);
}

9. What is the difference between null and undefined • null: intentional absence of value • undefined: variable declared but not assigned 10. What is the use of arrow functions Shorter syntax, no own this binding Example:

const add = (a, b) => a + b;

11. What is the DOM Document Object Model — represents HTML as a tree structure. JavaScript can manipulate it using methods like getElementById, querySelector, etc. 12. What is the difference between call, apply, and bind • call: invokes function with arguments passed individually • apply: invokes function with arguments as array • bind: returns a new function with bound context 13. What is the use of setTimeout and setInterval • setTimeout: runs code once after delay • setInterval: runs code repeatedly at intervals 14. What is the difference between stack and heap • Stack: stores primitive values and function calls • Heap: stores objects and reference types 15. What is the use of the spread operator (...) Expands arrays/objects or merges them Example:

const arr = [1, 2];
const newArr = [...arr, 3]; // [1, 2, 3]

16. What is the difference between map and forEach • map: returns a new array • forEach: performs action but returns undefined 17. What is the use of localStorage and sessionStorage • localStorage: persists data even after browser is closed • sessionStorage: persists data only for session 18. What is a prototype in JavaScript Every object has a prototype — an object it inherits methods and properties from. Enables inheritance. 19. What is the difference between synchronous and asynchronous code • Synchronous: executes line by line • Asynchronous: executes independently, doesn’t block main thread 20. What are modules in JavaScript Used to split code into reusable pieces Example:

// file.js
export const greet = () => "Hello";

// main.js
import { greet} from './file.js';
