Windows
The examples shown in posts frequently use the Linux command line because that’s what I typically work with (Linux and Mac OS X).
Windows 10 does have WSL, Windows Subsystem for Linux – not installed by default.
There is also cygwin, which provides a reliable clone of the Linux command line for earlier versions of Windows.
Various languages and utilities are easily installable on Windows: Nodejs, Python, Java. These can be run from the ordinary Windows command console.
The Tomcat and Jetty HTTP servers are easily installable on Windows, as are Apache and Nginx.
