Node.js is an asynchronous event-driven JavaScript runtime environment, designed to build scalable network applications. It is an open-source technology created by Ryan Dahl in 2009, and currently distributed by the Open JS Foundation. Node has been adopted by many notable companies, like Groupon, IBM and LinkedIn.

What is NodeJS?
How Node.js works
NodeJS runtime executes JavaScript code outside of a web browser; it lets developers run scripts on the server-side to produce dynamic web page content before the page is sent to the user’s web browser. In this operation, all the code is produced with JavaScript, eliminating the need to use different languages for server- and client-end. NodeJS combines the simplicity of the JavaScript language with the power of Unix network programming. Non-blocking I/O operations are supported by this environment, increasing the capacity to run many processes simultaneously. There are thousands of open-source libraries for Node.js.
Key benefits of NodeJS
- Node.js is highly scalable, either by the addition of nodes to the existing system or by the addition of extra resources.
- JavaScript is one of the most popular programming languages; NodeJS allows any front-end developer to start developing back-end applications with this same language without spending much time and effort.
- NodeJS is a full-stack JavaScript, reducing compatibility issues.
- Node.js has a high runtime performance and rendering speed.
- The possibility of caching single modules is offered, meaning that webpages are loaded faster and respond more promptly to the user.
When to use Node.js
Node.js is well suited for the foundation of a web library or framework. It is primarily used to build network programs such as web servers. The most important characteristic of NodeJS is the ability to develop both front-end and back-end applications with JavaScript, allowing you to save resources in contracting (you only need proficient JavaScript developers) and in solving compatibility issues.
Things to note before using Note.js
There is a large community of developers who keep contributing to the development of NodeJS. Some issues with backward compatibility have appeared on the Application Programming Interface of the more recent versions of Node.js.
