Node.js is free and open-source, which means it can be integrated into any web application quickly and easily.
Node has some great features that set it apart from other server-side frameworks: it's scalable, fast, and easy to learn (which makes it ideal for newcomers).
It allows you to write non-blocking code and therefore, it can handle thousands of simultaneous connections without any delay.
Asynchronous programming makes it fast and efficient for web applications, especially for data processing tasks that involve high volume data transfers between clients and servers.
The event looping model makes Node.js development very efficient. It makes your app more responsive as it processes each request individually without holding up other requests.
With its asynchronous event-driven architecture, Node.js excels at handling data, allowing multiple processes to run simultaneously.
Node's package ecosystem (NPM) is the largest ecosystem of open source libraries in existence today (more than 2 million at last count), which means that there is an extensive library available for virtually anything you could imagine building into your app!
Most Node.JS applications are real-time by default. This makes Node.JS web development ideal for gaming applications, chat applications, collaboration tools, real-time data streaming, and IoT (Internet of Things).
