Asynchronous I/O is possible because to Node.js' event-driven architecture. These design choices are aimed at increasing throughput and scalability in web applications with a lot of input/output activities, as well as real-time Web applications (e.g., real-time communication programs and browser games).
The Node.js distributed development project was previously managed by the Node.js Foundation, however that organization has now merged with the JS Foundation to form the Open JS Foundation, which is funded by the Linux Foundation's Collaborative Projects program.
The Node.js programming language is generally used to create network programs such as Web servers. The most notable distinction between Node.js and PHP is that most PHP functions block until they are complete (ones run only after preceding commands have been completed), whereas Node.js functions are non-blocking (commands execute concurrently or even in parallel, and use callbacks to signal completion or failure).
Official support for Node.js is available for Linux, macOS, and Microsoft Windows 8.1 and Server 2012 (and later), with tier 2 support for SmartOS and IBM AIX, as well as experimental support for FreeBSD. OpenBSD is also supported, with LTS versions for IBM I (AS/400) available. The provided source code can also be constructed on operating systems that are similar to those that are officially supported, or updated by third parties to support additional operating systems like NonStop OS and Unix servers.
