If path uses. For the end, will return.. If the file does not have an extension, it does not. At the end, or the file does not have an extension, a null value is returned.

Path.extname ('/ path/to/index.') / /'. Path.extname ('/ path/to/README') / / 'path.extname (' / path/to/.gitignore') / /''

2. Path.basename () and path.dirname (), get the file name (including extension) and directory, respectively.

Path.basename ('/ path/to/test.txt') / / 'test.txt'path.dirname (' / path/to/test.txt') / /'/ path/to'

3. Path.parse () returns the object.

The object contains paths divided into five different components.

Includes extensions and directories. The path.parse () method is also a way to get the file name without any extension.

Path.parse ('/ path/to/test.txt') / * {root:'/', dir:'/ path/to', base: 'test.txt', ext:' .txt', name: 'test'} * / "what are the Path methods in Node.js?" Thank you for reading.
