What is Node.js?

Jul 21, 2021

What I did understand about node js

Node.js is an environment (platform) for developing server applications in the JavaScript language.

It is a platform that allows you to run JavaScript on the server-side.

Server-side and client-side can be developed in a single language (JavaScript).
Uses the Google V8 JavaScript engine, which can handle large amounts of access at high speed.
- Scalable network applications can be easily built.
The non-blocking I/O processing method makes it suitable for real-time applications that are lightweight and span distributed devices.

A method that executes input/output processing in an **asynchronous** manner.

For example, when a query is issued to a database, it moves to the next processing without waiting for the result to be returned.

And the result is received by an event.

I/O is an abbreviation for `input/output` (input/output).
