path.join()

path.join([path1][, path2][, ...])

Join all arguments together and normalize the resulting path.

Arguments must be strings. In v0.8, non-string arguments were silently ignored. In v0.10 and up, an exception is thrown.

Example:

path.join('/foo', 'bar', 'baz/asdf', 'quux', '..')
// returns '/foo/bar/baz/asdf'

path.join('foo', {}, 'bar')
// throws exception
TypeError: Arguments to path.join must be strings

Note: If the arguments to join have zero-length strings, unlike other path module functions, they will be ignored. If the joined path string is a zero-length string then '.' will be returned, which represents the current working directory.
