π 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.
π 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.
π 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.
π 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.
π 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.
π 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).
π 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.
π 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.
π 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).
π π What are WebSockets?
Answer: WebSockets provide full-duplex communication channels over a single TCP connection, enabling real-time data flow between client and server.
π‘ Pro Tip: Back answers with examples or a small snippet, and relate them to projects youβve built. Be ready to explain trade-offs between technologies.
