4. What is the DOM
Document Object Model — a tree-like structure representing HTML elements. JavaScript can manipulate it to update content dynamically.
5. What is the difference between GET and POST methods
• GET: Sends data via URL, used for fetching
• POST: Sends data in body, used for submitting forms securely
6. What is the box model in CSS
Every HTML element is a box:
Content → Padding → Border → Margin
7. What is the difference between relative, absolute, and fixed positioning in CSS
• Relative: Moves element relative to its normal position
• Absolute: Positions element relative to nearest positioned ancestor
• Fixed: Stays in place even when scrolling
8. What is the difference between == and === in JavaScript
• ==: Compares values with type coercion
• ===: Strict comparison (value and type)
9. What is event bubbling in JavaScript
Events propagate from child to parent elements. Can be controlled using stopPropagation().
10. What is the difference between localStorage and sessionStorage
• localStorage: Persistent across sessions
• sessionStorage: Cleared when tab is closed
11. What is a RESTful API
An architectural style for designing networked applications using HTTP methods (GET, POST, PUT, DELETE) and stateless communication.
12. What is the difference between frontend and backend development
• Frontend: Client-side (UI/UX, HTML/CSS/JS)
• Backend: Server-side (databases, APIs, authentication)
13. What are common HTTP status codes
• 200 OK
• 404 Not Found
• 500 Internal Server Error
• 403 Forbidden
• 301 Moved Permanently
14. What is a promise in JavaScript
An object representing the eventual completion or failure of an async operation.
States: pending, fulfilled, rejected
15. What is the difference between synchronous and asynchronous code
• Synchronous: Executes line by line
• Asynchronous: Executes independently, doesn’t block the main thread
16. What is a CSS preprocessor
Tools like SASS or LESS that add features to CSS (variables, nesting, mixins) and compile into standard CSS.
17. What is the role of frameworks like React, Angular, or Vue
They simplify building complex UIs with reusable components, state management, and routing.
18. What is the difference between SQL and NoSQL databases
• SQL: Structured, relational (e.g., MySQL)
• NoSQL: Flexible schema, document-based (e.g., MongoDB)
19. What is version control and why is Git important
Version control tracks changes in code. Git allows collaboration, branching, and rollback. Platforms: GitHub, GitLab, Bitbucket
