What programming languages are available immediately for standard installation on each operating system?

There will be no common programming language for the listed operating systems.Today, computers are more used for other purposes than for programming purposes.Additionally, a variety of tools are available to assist with programming, so they are not often considered ready to use immediately after installation (assuming that developers will install the tools they want).

Let's talk about Windows as an example.For Windows 7 and later, the following are standard installations:

• C#Compiler
• Visual Basic Compiler
• PowerShell (will be discontinued but will also come with IDE)
• CMD (so-called batch file)
• JScript Run Environment
• VBScript running environment

Apart from the embedded OS, the modern OS is standard and has a browser, so
Javascript (+HTML, CSS) seems to be highly versatile.
I think Electron and NWjs are popular against that background.
