How does the server process requests, synchronously or asynchronously?

Question

Node.js

Using the API, I send several requests, how does the server process them: does it queue them up and process each one in turn, or does it asynchronously respond to all at once?

Answer 1

depends on the code: it can be parallel processing, it can be sequential.
read about blocking operations.
