nodejs dirname
// Source Code: lib/path.js
// Description: The path module provides utilities for working with file and
// directory paths. It can be accessed using:
const path = require('path')
path.dirname('/foo/asdf/quux')
// Returns: '/foo/asdf'
/* dirname(Value <string>) Returns: <string>
The path.dirname() method returns the directory name of a path,
similar to the Unix dirname command. Trailing directory separators
are ignored, see path.sep. A TypeError is thrown if path is not a string. */
