Description
What are the differences between blocking and non-blocking calls in the context of Node.js?
1. Understanding of Node.js event-driven architecture : Your ability to explain how Node.js handles operations and the role of its event-driven architecture.
2. Knowledge of asynchronous programming : Your familiarity with async programming practices and patterns, particularly in Node.js.
3. Comprehension of I/O operations : Your understanding of input/output operations and how they're managed by blocking and non-blocking approaches.
4. Problem solving and reasoning : Your capability to analyze and articulate the implications of using blocking versus non-blocking calls.
1. Assessing fundamental Node.js knowledge : Determining if you have a solid grasp of core Node.js concepts.
2. Evaluating practical understanding : Understanding if you can apply theoretical knowledge to real-world Node.js programming challenges.
3. Judging decision-making abilities : Seeing if you can make informed decisions about when to use blocking or non-blocking calls.
4. Checking for performance optimization awareness : Evaluating if you are aware of the impact that call types can have on application performance.
1. Consider event loop : Think about how the event loop works in Node.js and how blocking calls can affect its operation.
2. Give real-world examples : Mention practical use cases or examples where you would use blocking versus non-blocking calls in Node.js applications.
3. Explain backpressure concept : Discuss what backpressure is and how it relates to non-blocking I/O, for a more in-depth answer.
