πŸ“ 1. What is the difference between Frontend and Backend development?
Answer: Frontend deals with the part of the website users interact with (UI/UX), using HTML, CSS, JavaScript frameworks like React or Vue. Backend handles server-side logic, databases, and APIs using languages like Node.js, Python, or PHP.

πŸ“ 2. What is REST and why is it important?
Answer: REST (Representational State Transfer) is an architectural style for designing APIs. It uses HTTP methods (GET, POST, PUT, DELETE) to manipulate resources and enables communication between client and server efficiently.

πŸ“ 3. Explain the concept of Responsive Design.
Answer: Responsive Design ensures web pages render well on various devices and screen sizes by using flexible grids, images, and CSS media queries.

πŸ“ 4. What are CSS Flexbox and Grid?
Answer: Both are CSS layout modules. Flexbox is for one-dimensional layouts (row or column), while Grid manages two-dimensional layouts (rows and columns), simplifying complex page structures.

πŸ“ 5. What is the Virtual DOM in React?
Answer: A lightweight copy of the real DOM that React uses to efficiently update only parts of the UI that changed, improving performance.

πŸ“ 6. How do you handle authentication in web applications?
Answer: Common methods include sessions with cookies, tokens like JWT, OAuth, or third-party providers (Google, Facebook).

πŸ“ 7. What is CORS and how do you handle it?
Answer: Cross-Origin Resource Sharing (CORS) is a security feature blocking requests from different origins. Handled by setting appropriate headers on the server to allow trusted domains.

πŸ“ 8. Explain Event Loop and Asynchronous programming in JavaScript.
Answer: Event Loop allows JavaScript to perform non-blocking actions by handling callbacks, promises, and async/await, enabling concurrency even though JS is single-threaded.

πŸ“ 9. What is the difference between SQL and NoSQL databases?
Answer: SQL databases are relational, use structured schemas with tables (e.g., MySQL). NoSQL databases are non-relational, schema-flexible, and handle unstructured data (e.g., MongoDB).

πŸ“ πŸ”Ÿ What are WebSockets?
Answer: WebSockets provide full-duplex communication channels over a single TCP connection, enabling real-time data flow between client and server.

πŸ’‘ Pro Tip: Back answers with examples or a small snippet, and relate them to projects you’ve built. Be ready to explain trade-offs between technologies.
