{{ APIRef("URL API") }} {{AvailableInWorkers}}
The hash property of the {{domxref("URL")}} interface is a string containing a "#" followed by the fragment identifier of the URL. If the URL does not have a fragment identifier, this property contains an empty string, "".
This property can be set to change the fragment identifier of the URL. When setting, a single "#" prefix is added to the provided value, if not already present. Setting it to "" removes the fragment identifier.
The fragment is {{Glossary("Percent-encoding", "percent-encoded")}} when setting but not percent-decoded when reading.
A string.
