Node.js is a cross-platform framework to build network applications with JavaScript programming languages. Applications developed with Node.js use an event-driven method, and its most important feature is to develop a non-blocking I/O model for a network application. Node.js applications mainly use network sockets for I/O.
There are also some APIs provided to developers to interact with low-level C APIs in order to develop applications with sensors connected to platforms. Node.js is embraced by the maker community as well. They use it to build simple applications for devices like Intel Galileo. When we build the full image for an SD card, it will include Node.js and we can work with it.
