 The querystring module provides utilities for parsing and formatting
 URL query strings.

 On the World Wide Web, a query string is the part of a uniform
 resource locator (URL) containing data that does not fit conveniently
 into a hierarchical path structure. The query string commonly includes
 fields added to a base URL by a Web browser or other client
 application, for example as part of an HTML form.

 stringify query string.
