Sure, JavaScript is a capable and feature-rich *high-level* language. NodeJS
provides decent access to OS facilities, and NPM is a reliable source of
additional functionality (even if it is no CPAN, or not yet CPAN). But I’d say,
stepping strictly into personal opinion or preference territory, JavaScript (or
Python for that matter) will never be as comfortable for sys-admin tasks as
Perl. If having to carry the cognitive load of thorough-going async for
inherently synchronous activities does not tax you, then the lack of Perl’s
terse and intuitive (for a Unix-head) syntax for things like file test (-f, -l,
etc), pipes (“|”), regular expressions, program execution (``), etc, might.
Even if they do, it might be a small price to pay *if* the rest of your code is
JavaScript/NodeJS.

Sorry, I do not know of any.
