2. What is the difference between == and ===
•
•
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:
5. What is the difference between var, let, and const
•
•
•
6. What is event delegation
Using a single event listener on a parent element to handle events from its child elements using

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-assigned6. 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 assigned10. What is the use of arrow functions
Shorter syntax, no own
this bindingExample:
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 context13. What is the use of setTimeout and setInterval
•
setTimeout: runs code once after delay•
setInterval: runs code repeatedly at intervals14. 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 undefined17. What is the use of localStorage and sessionStorage
•
localStorage: persists data even after browser is closed•
sessionStorage: persists data only for session18. 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';

✅ Top JavaScript Interview Questions & Answers 💻✨
📍 1. What is JavaScript and why is it important?
Answer: JavaScript is a dynamic, interpreted programming language that makes web pages interactive. It runs in browsers and on servers (Node.js), enabling features like animations, form validation, and API calls.
📍 2. Explain the difference between var, let, and const.
Answer:
📍 3. What are closures in JavaScript?
Answer: Closures occur when a function remembers and accesses variables from its outer scope even after that outer function has finished executing.
📍 4. What is the Event Loop?
Answer: The Event Loop manages asynchronous callbacks by pulling tasks from the callback queue and executing them after the call stack is empty, enabling non-blocking code.
📍 5. What are Promises and how do they help?
Answer: Promises represent the eventual completion or failure of an asynchronous operation, allowing cleaner async code with
📍 6. Explain 'this' keyword in JavaScript.
Answer:
📍 7. What is prototypal inheritance?
Answer: Objects inherit properties and methods from a prototype object, allowing reuse and shared behavior in JavaScript.
📍 8. Difference between == and === operators?
Answer:
📍 9. How do you handle errors in JavaScript?
Answer: Using
📍 🔟 What are modules in JavaScript and their benefits?
Answer: Modules split code into reusable files with
💡 Pro Tip: Complement your answers with simple code snippets and real project scenarios wherever possible.

Answer: JavaScript is a dynamic, interpreted programming language that makes web pages interactive. It runs in browsers and on servers (Node.js), enabling features like animations, form validation, and API calls.
📍 2. Explain the difference between var, let, and const.
Answer:
var has function scope and is hoisted; let and const have block scope. const defines constants and cannot be reassigned.📍 3. What are closures in JavaScript?
Answer: Closures occur when a function remembers and accesses variables from its outer scope even after that outer function has finished executing.
📍 4. What is the Event Loop?
Answer: The Event Loop manages asynchronous callbacks by pulling tasks from the callback queue and executing them after the call stack is empty, enabling non-blocking code.
📍 5. What are Promises and how do they help?
Answer: Promises represent the eventual completion or failure of an asynchronous operation, allowing cleaner async code with
.then(), .catch(), and async/await.📍 6. Explain 'this' keyword in JavaScript.
Answer:
this refers to the context object in which the current function is executed — it varies in global, object, class, or arrow function contexts.📍 7. What is prototypal inheritance?
Answer: Objects inherit properties and methods from a prototype object, allowing reuse and shared behavior in JavaScript.
📍 8. Difference between == and === operators?
Answer:
== compares values after type coercion; === compares both value and type strictly.📍 9. How do you handle errors in JavaScript?
Answer: Using
try...catch blocks for synchronous code and .catch() or try-catch with async/await for asynchronous errors.📍 🔟 What are modules in JavaScript and their benefits?
Answer: Modules split code into reusable files with
import and export. They improve maintainability and scope management.💡 Pro Tip: Complement your answers with simple code snippets and real project scenarios wherever possible.
