How to understand how many threads node.js can handle?

Question

Node.js

I'm trying to understand the intangible model of asynchronous development for Node.js, in particular questions like how to understand how many threads can node.js withstand? what are these threads and how to track them?

Answer 1

Very often, threads mean both threads and parallel processes.
If by threads you mean processes, then in nodejs they are implemented using workers. As far as I know, there are no other implementations in the node. A little is written about them here and here (in the comments they hint at performance tests and other things, maybe even someone conducted them)
If you are interested in streams, then you can get acquainted with them a little here
For a more detailed answer, I would like a more detailed question.
