4. What is the DOM
Document Object Model โ a tree-like structure representing HTML elements. JavaScript can manipulate it to update content dynamically.

โข 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 โ Padding โ Border โ Margin
7. What is the difference between relative, absolute, and fixed positioning in CSS
โข Relative: Moves element relative to its normal position
โข Absolute: Positions element relative to nearest positioned ancestor
โข Fixed: Stays in place even when scrolling
8. What is the difference between == and === in JavaScript
โข ==: Compares values with type coercion
โข ===: 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
โข localStorage: Persistent across sessions
โข 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
โข Frontend: Client-side (UI/UX, HTML/CSS/JS)
โข Backend: Server-side (databases, APIs, authentication)
13. What are common HTTP status codes
โข 200 OK
โข 404 Not Found
โข 500 Internal Server Error

โข SQL: Structured, relational (e.g., MySQL)
โข 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
20. How do you optimize website performance
โข Minify CSS/JS
