URL: pathname property

Note: This feature is available in Web Workers.

The pathname property of the URL interface represents a location in a hierarchical structure. It is a string constructed from a list of path segments, each of which is prefixed by a / character. If the URL has no path segments, the value of its pathname property will be the empty string.

URLs such as https and http URLs that have hierarchical schemes (which the URL standard calls "special schemes") always have at least one (invisible) path segment: the empty string. Thus the pathname value for such "special scheme" URLs can never be the empty string, but will instead always have a least one / character.

For example, the URL https://developer.mozilla.org has just one path segment: the empty string, so its pathname value is constructed by prefixing a / character to the empty string.

Some systems define the term slug to mean the final segment of a non-empty path if it identifies a page in human-readable keywords. For example, the URL https://example.org/articles/this-that-other-outre-collection has this-that-other-outre-collection as its slug.

Some systems use the ; and = characters to delimit parameters and parameter values applicable to a path segment. For example, with the URL https://example.org/users;id=42/tasks;state=open?sort=modified, a system might extract and use the path segment parameters id=42 and state=open from the path segments users;id=42 and tasks;state=open.
