Why is Node.js single-threaded? Answer: Node.js uses a single-threaded event loop to handle asynchronous tasks, which allows it to manage high concurrency without multi-threading. 3. Explain the difference between async and await in Node.js. Answer: async declares a function as asynchronous, while await is used inside an async function to wait for a Promise to be resolved or rejected.

r/node on Reddit: Important topics and questions to prepare for NodeJS interview
June 20, 2023 -
A little bit of context: I have completed projects and created my resume. I am prepared for interviews in terms of projects. However, it seems that they usually ask theoretical questions such as "What is the Event Loop?" or "What are streams?" For those who have experience in conducting or participating in interviews, what do you think are the important topics and questions I should be prepared for?
Additionally, I primarily work on the backend using Node.js. I have previously used React.js in past projects, but I found frontend development to be challenging, which led me to shift my focus. However, I am capable of implementing a full-stack web application if a frontend template is provided. Should I also prepare for advanced theoretical questions (beyond the basics) on React? If so, what are the key areas I should focus on at a minimum?

Get your JS fundamentals down, what are closures, object prototype, event loop, etc. Then get your web fundamentals down, HTTP (headers, methods, cookie, body, status code), what is DNS, what is a CDN, how to do caching (and cache invalidation), OSI layers (probably don’t need to know too much, but you should be able to explain UDP/TCP vs HTTP). If you’re doing full stack, SQL, architecture (load balancing, high availability) These are what I ask when I interviewing a mid to senior role. Good luck!
