Some Posix system examples:

// will be returned.
path.format({

// if `base` is not specified
// `root` will be used if `dir` is not specified.
// `name` + `ext` will be used if `base` is not specified.
// If only `root` is provided or `dir` is equal to `root` then the
// platform separator will not be included.
