What is node js used for?
Node. js is primarily used for non-blocking, event-driven servers, due to its single-threaded nature. It’s used for traditional web sites and back-end API services, but was designed with real-time, push-based architectures in mind.
Why is node so popular?
Why is Nodejs bad?
Is node JS declining already?

Is node js better than PHP?
Why is node so fast?
It’s partly due to the fact a multi-threaded program can run on multiple cores but the main reason, by far, is that when a thread is waiting for some IO operation (which is very often, especially in a server), the other threads can still progress.

How many requests can node handle?
js uses a single-thread and an event loop to process requests only processing one at a time (which is non-blocking). But still, how does that work, lets say 10,000 concurrent requests.
How does node handle concurrency?
your code) only has access to a single thread, but Node. js transparently hands off the io to a separate thread without the user needing to deal with it. In your case, function one and two are both running in the same thread, but the actual io operations to read the file data were performed in separate threads.
How many connections can a node js server handle?

So each concurrent TCP connection is an open file. Knowing that our limit is 1024, that would indicate that node. js could handle up to 256 concurrent users if each user uses the maximum of 4 open connections.
How difficult is node JS?
Who uses node JS?
#1 Netflix Netflix, the world’s leading Internet television network with over 117 million users, is one of those top companies that trusted his servers to Node. js. It uses copious amounts of A/B testing to provide a rich experience for the users of its high-capacity data-driven platform.
