node.js

node.js provides users with a cross-platform open-source JavaScript runtime environment that allows the execution of JavaScript code outside of a browser. According to its parent companies OpenJS and Joyent Inc., node.js is specifically designed for the development of scalable network applications. It is similarly structured and inspired by systems like Ruby's Event Machine and Python's Twisted. However, node.js takes their principles a step further. The general advantages are increased productivity and efficiency, data streaming, compatibility with microservices, fast functionality, usability as a proxy server, usability as a codebase for frontend and backend, and the ideal suitability for IoT applications. node.js is completely free to use. It is available for all major platforms.
