Indeed, VS Code uses a remote server for that, see
<https://code.visualstudio.com/docs/remote/remote-overview>. It does not
require you to install it manually, adding the "Remote Development
extension pack" does the trick. This installs the remote VS Code server
on the remote host when needed.

OTOH, Tramp uses a remote shell as a REPL engine. That is another
approach, and less performant.

(In the past I've tried to use remote Perl or Python programs as REPL
engine, but the performance was even worse).

Yes.
