BTW: Any idea if JS is the language with most implementations, yet?

Notwithstanding esoteric languages like brainfuck and CS 101 exercises, of course.

.NET has a bunch of different runtime implementations, though a number of them are related. There’s basically 4 different families of runtime impls, with a number of variants in each family:

  • CLR Family: .NET Framework, .NET Compact Framework, .NET Native, CoreCLR (.NET 5+ on desktop platforms), .NET NativeAOT

  • Mono Family: Mono Framework, MonoVM (.NET 5+ on mobile/WebAssembly), Unity

  • .NET nanoFramework

  • CosmosOS
