Except that with Deno, everything IO related is turned off by default and has to be granted access before it becomes a process. It's the first bullet point on the landing page.

Here is the page with more detail. https://deno.land/manual/getting_started/permissions

It can even restrict access down to a specific directory or host. This is cool.

Whereas any NPM module can map your subnet, lift your .ssh directory, and yoink environment variables, wily-nily.

That still doesn't prevent imported modules from yoinking anything you did grant access to, though. For instance, if my service connects to a DB then `uuid` can slurp the contents.
