Permissions

===Unless you specifically enable it, a program run with Deno has no file, network, or environment access.===

deno run --allow-read mod.ts

The above command gives only read access to the file system. It cannot write to the file system, or perform any other security sensitive functions

There are officially lot of permissions that you can set or give. Go to official docs for more information about usage and more.
