interface Deno.MkdirOptions
Options which can be set when using Deno.mkdir and
Deno.mkdirSync.
optional
recursive: boolean = false
If set to true, means that any intermediate directories will also be
created (as with the shell command mkdir -p).
Intermediate directories are created with the same permissions.
When recursive is set to true, succeeds silently (without changing any
permissions) if a directory already exists at the path, or if the path
is a symlink to an existing directory.
optional
mode: number
Permissions to use when creating the directory (defaults to 0o777,
before the process's umask).
Ignored on Windows.
