Introduction

Node JS is a JavaScript runtime built on Chrome's V8 Javascript Engine.

Node JS is an asynchronous event-driven JavaScript runtime, it is used to develop scalable networks and dynamic web applications.

NODE JS consists of a lot of inbuilt and third-party modules which are invoked in the application to be developed. We can also create our modules in NODE JS.

It is an open-source server environment.

It supports various platforms including Windows, Linux, and macOS.

Node.js = Runtime Environment + JavaScript Library

We know that when a user requests something from a server, the server needs to send the response to the client and many programming languages and platforms have different methods of handling the requests and responses in a different manner. Here is how PHP and NODE JS handle the request-response.


Features

Asynchronous and Event-driven Environment:

A NODE JS program or the API runs asynchronously which makes the application boost and it never waits for another program in order to execute the current task.

Dynamic:

Node JS is dynamic and flexible with its wide variety of packages offered with NPM

Speed:

Applications built on NODE JS are very scalable in real-time and are speedy due to NODE JS's non-blocking nature.
