function Deno.makeTempDir
makeTempDir(options?: MakeTempOptions): Promise<string>
Creates a new temporary directory in the default directory for temporary
files, unless `dir` is specified. Other optional options include
prefixing and suffixing the directory name with `prefix` and `suffix`
respectively.
This call resolves to the full path to the newly created directory.
Multiple programs calling this function simultaneously will create different
directories. It is the caller's responsibility to remove the directory when
no longer needed.
```ts
const tempDirName0 = await Deno.makeTempDir(); // e.g. /tmp/2894ea76
const tempDirName1 = await Deno.makeTempDir({ prefix: 'my_temp' }); // e.g. /tmp/my_temp339c944d
```
Requires `allow-write` permission.
