interface Deno.MkdirOptions
Options which can be set when using [`Deno.mkdir`](../././~/Deno.mkdir) and
[`Deno.mkdirSync`](../././~/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.
