Node.js uses a single thread for connection requests which allows it to support thousands of concurrent connections necessary for network applications that demand high throughput for scaling. It allows users to write their modules, reusable codes that can be used across applications. It is built on an architecture that allows event-driven programming on web servers which allow developers to create scalable servers without threading. It improves the efficiency of data-intensive real-time applications by using an event-driven, non-blocking I/O model.  

Programmers can publish and share source code of Node.js libraries using a package manager that simplifies installation, updating, and uninstallation of libraries. With its rich library of JavaScript modules, Node.js simplifies the development of web applications. By using JavaScript on both server-side and client-side, Node.js reduces infrastructure needs and response times.
