Node.JS

 

Node.JS

A runtime environment for executing JavaScript code is open source for developing server-side and networking application

Features of Node.JS

Asynchronous and Event-Driven

The primary organizational concept of Node is to eliminate blocking processes by using event-driven, asynchronous I/O. This design aids developers in shaping data and increasing capacity. Node allows you to create and organize lightweight, self-contained, and share-nothing processes that communicate through callbacks and synchronize with a predetermined event loop.

Single-Threaded but Highly Scalable, data-intensive, real-time

Node.js is single-threaded but in the background it uses multiple threads to execute asynchronous code

This feature because of the non-blocking asynchronous nature of node

Has single thread is used to handle multiple requests. It is behind the scene of non-blocking and asynchronous concept

 

Very Fast

Node JS library is very fast in code execution
