Node.js

Node.js runs JavaScript programs outside a web browser, letting developers execute application logic directly on a Windows computer or server. It supplies the runtime foundation for building web applications and network services that respond to requests and coordinate other software components. Developers can also use the same environment to create command-line utilities and automation scripts.

Its event-driven runtime is suited to programs that handle many input and output operations, while JavaScript can be shared across server-side tools and application code. The included npm ecosystem gives projects access to reusable modules and scripts, and the Node.js command line supports running files, evaluating code, and managing development tasks. This makes Node.js useful for web developers, backend programmers, and teams that need JavaScript in server, application, command-line, or scripting work.

The Windows release is published by the Node.js Foundation as Developer Tools software under an open-source license. Version 26.12.1 supports x64 systems running Windows 8.1 or later, as well as Windows Server 2012 R2 and later. It is intended for people who write or maintain JavaScript software and need a runtime that can carry that language across several kinds of development projects.
