PowerShell is available on macOS and Linux as well (source on Github: https://github.com/PowerShell/PowerShell). It may not be as well-integrated with things like system services management, but the language still works well. You can still use all the command line tools you're used to on Linux, of course.
nushell does look interesting, though the lack of a .deb repository does put it pretty low on my to-do list.
I didn't know of `jc`, but it seems that using nushell (https://github.com/nushell/nushell) gets you a better experience.
