Author: User

Event-driven: trigger an event and then call the relevant available resources to solve the event.

Asynchronous: you do not need to wait for the return value of the called function to make the next call.

I/O: Short for input/output, that is, the input/output port.

 

First, node is an architecture that serves I/O through event-driven.

In node, JS can access local files as you like, build a websocket server, and connect to a database. It can play multiple processes like Web worders.
