NodeJS

Node.js is a cross-platform open-source environment for developing server and network applications. Applications are written in JavaScript and can run in the Node.js runtime environment on OS X, Microsoft Windows and Linux. Node.js uses an event-driven, non-blocking I/O model which makes it simple and efficient, ideal for data-intensive, real-time applications running across distributed devices.

The most important thing to understand is that Node.js is not a server. It doesn't have configuration files like Apach, for example, and Node by itself doesn't do anything. It's an execution environment for JavaScript code-another way to run it on a computer. And if we need that platform to be an HTTP server, we have to write it ourselves.

Node.js applications are written in JavaScript and can run in runtime environments on OS X, Windows, and Linux. Node.js is great for scalable, high-load projects. It can also be used to create synchronous cross-platform solutions - for example, when you send a message from your phone, it appears in the web version of the application and in the desktop version. And Node.js is most often used to create web servers.

Node.js is a server-side JavaScript execution environment used to build fast, scalable network applications.

The main advantages of using it are:

Convenience for building fast applications because Node is capable of handling a huge number of simultaneous connections with high bandwidth. This attracts many programmers who want to build sites that support millions of visitors;

Efficiency. In a web application, it takes the most time to complete all of your database queries. With Node.js, you can execute them all at once, reducing the response time for slow requests;

JavaScript development language. You can split the code between the browser and your back-end. JavaScript is on its way to becoming a truly universal language;

speed of execution. The V8 engine is constantly pushing the boundaries and is one of the fastest dynamic language interpreters on the planet. In addition, Node's I/O facilities are really lightweight, bringing you as close to using the full potential of your I/O system as possible.

Node is handy for building fast applications https://devoxsoftware.com/technology/node-js-development-services/, because it can handle a huge number of simultaneous connections with high throughput. This attracts many programmers who want to build sites that support millions of visitors.

Many large companies use this platform to build their own websites. Today it is rightfully considered one of the leading platforms for web development, and most of the web tools, server-side and client-side, work with it.
