How to create your own website from scratch??

Define Your Goals and Audience: Clearly outline the purpose of your website and who your target audience is. This will guide your design and content decisions.
Choose a Domain Name: Select a domain name that's easy to remember, relevant to your content, and reflects your brand or purpose.
Select a Web Hosting Provider: Research and choose a web hosting provider that meets your needs in terms of storage, bandwidth, security, and support.
Plan Your Website Structure: Create a sitemap that outlines the hierarchy of your website's pages. This will help you organize content and navigation.
Wireframing and Mockups: Use wireframing tools like Balsamiq, Figma, or Adobe XD to create mockups of your website's layout and design.
Create Content: Start creating content for each page, including text, images, videos, and any other media you plan to use.
Learn HTML and CSS: Familiarize yourself with HTML for structuring content and CSS for styling. There are many online tutorials and resources available.

✅ Detailed Roadmap to Become a JavaScript Developer

📂 Start with Programming Basics
Understand variables, data types, loops, functions, and conditional statements. Build logical thinking first.

∟📂 Learn JavaScript Fundamentals
Master core JS concepts:
– var, let, const
– Functions, Scope, Hoisting
– Arrays & Objects
– DOM Manipulation
– Events & Event Handling

∟📂 Understand ES6+ Features
Learn modern syntax like arrow functions, destructuring, template literals, promises, async/await, and modules.

∟📂 Master the Browser Environment
Explore how JS works in browsers, including:
– BOM (Window, Navigator, History)
– DOM Traversal & Manipulation
– Fetch API & AJAX

∟📂 Learn Debugging & Dev Tools
Use Chrome DevTools to inspect, debug, and optimize your code effectively.

∟📂 Build Projects (Vanilla JS)
Create small apps like a calculator, to-do list, or quiz app to strengthen your understanding.

∟📂 Learn Git & GitHub
Track your code, collaborate with others, and build your coding portfolio.

∟📂 Move to Advanced Topics
Study closures, prototypes, event loop, promises, this keyword, and memory management.

∟📂 Learn Frameworks (React preferred)
Pick a popular JS framework like React. Learn components, props, state, hooks, and routing.

∟📂 Understand Package Managers & Tooling
Get hands-on with NPM/Yarn, Webpack, Babel, ESLint, etc.

✅ 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';
