What operating systems have you used in your practice?

In practice with Node.js, I have used the following operating systems:

• Windows — for development and testing of applications in a familiar environment.
• Linux (Ubuntu, CentOS) — for server deployment and working with containers.
• macOS — for development, especially when working with cross-platform tools.

Each OS has its own features; for example, Linux makes it easier to work with the command line and server configuration, while Windows is often used for local development with a graphical interface.
