What is NodeJs used for?

Question

ASP.NET

If I understood the Wiki correctly, then it allows you to use JavaScript on the server side.
However, in view of my little experience, I cannot imagine tasks that could be solved only by his means.
Tell me, for what tasks is NodeJs usually used or is it some kind of narrowly focused thing?
Is it used in ASP.NET MVC?

Answer 1

node.js is a platform for writing full-fledged console and network utilities
. It uses v8 (the same as in the chrome browser) as a compiler and js virtual machine.
The platform itself provides api for working with the operating system, file system and network, and also for managing v8 and binding c++ extensions Main
use - server applications and console utilities

Answer 2

I will tell about myself, I chose nodejs, because I can write small programs for both Windows and Linux, and if necessary, I can make some kind of web service.
For example, I wrote a program for docker backup , for monitoring docker through icinga2 or made a webgui for apache derby .
Everything is written more or less quickly and there are a lot of modules.

Answer 3

Also how it is used. Starting from a package manager (nmp), building a project (webpack for example) to calling NodeJS applications from ASP.Net (it is definitely implemented in ASP.Net Core) and server-side pre-rendering of SPA applications.
