💬 Potential Interview Questions
-
What is the difference between useEffect and useLayoutEffect in React?
useEffectruns after the render is committed to the screen, whileuseLayoutEffectruns synchronously after all DOM mutations but before the browser has a chance to paint, useful for measuring layout. -
How do you manage state across a large React application?
State can be managed using Context API for global state or libraries like Redux/Zustand for more complex scenarios; React Query can be used for server state. -
Explain the event loop in Node.js.
The event loop is a single-threaded mechanism in Node.js that handles asynchronous operations using callbacks, promises, and I/O events in phases like timers, I/O callbacks, and idle/prepare. -
How do you structure a RESTful API using Express.js?
Organize routes by resource, use HTTP methods semantically, implement controllers for business logic, and ensure modular middleware for validation and authentication. -
What are key differences between SQL and NoSQL databases?
SQL databases are relational, use structured schemas, and support ACID transactions; NoSQL databases are schema-less, scalable, and ideal for unstructured or rapidly changing data. -
How do you ensure your Node.js backend is scalable?
Implement clustering, use asynchronous non-blocking code, adopt microservices when needed, and manage resources with tools like PM2 and load balancers. -
What are some best practices for code reviews?
Ensure readability, validate logic correctness, check for adherence to standards, suggest improvements, and focus on knowledge sharing over criticism. -
How would you implement CI/CD for a fullstack app?
Use tools like GitHub Actions or GitLab CI to automate tests, linting, builds, and deployments; containerize the app with Docker and deploy to services like AWS/GCP. -
How do you handle API errors in frontend and backend?
Use consistent error handling with try/catch and proper HTTP status codes on the backend, and show user-friendly messages or fallback UI on the frontend. -
What are benefits of using TypeScript in a fullstack application?
TypeScript provides static typing, reduces runtime errors, enhances IDE support, and improves collaboration by making code more predictable and self-documented.
