Getting Started with Deno — What is Deno?

The Allow All Flag

Deno does provide a flag that will give your application all the permissions it needs, and that flag is --allow-all or -A. While this may be useful, I'd discourage you from using it. The benefit of the permissions system Deno has created is that you will know what features a program is using. If you just allow all permissions, a third party module could use a feature that you don't want it to use.
