Introducing Node.js

Node js is an open-source, cross-platform, back-end JavaScript runtime environment that allows developers to build server-side applications using JavaScript It was created by Ryan Dahl in 2009 and is built on top of the Google Chrome V8 JavaScript engine

Node.js uses an event-driven, non-blocking I/O model, making it efficient and lightweight. This means that it can handle a large number of simultaneous connections without blocking the execution of other tasks, which is crucial for building scalable web applications.

Node.js has a rich ecosystem of modules and packages, which can be easily installed and managed using npm (Node Package Manager). This makes it easy for developers to add new functionality to their applications and reuse code written by others.

Node js is widely used for building web servers, APIs, real-time chat applications, streaming services, and many other types of server-side applications It has gained popularity in recent years because of its ability to handle large-scale, hightraffic applications and its compatibility with modern web technologies such as WebSocket and WebRTC.

Advantages:

Node.js is highly performant and efficient due to its non-blocking I/O model.

Its use of JavaScript makes it easy to learn and use.

The rich ecosystem of modules and packages makes it easy to add functionality and reuse code.

It’s highly scalable and can handle large-scale, high-traffic applications.

It’s well-suited for building real-time applications like chat and online games

The active community of developers ensures that Node js is constantly evolving and improving

Key features:

An asynchronous and event-driven programming model

Fast and scalable

Single-threaded but supports concurrency

JavaScript-based, making it easy to learn and use

A large and active ecosystem of packages and modules through NPM (Node Package Manager)

Well-suited for real-time applications and microservices architecture

Cross-platform and open-source
