Web/API/URL/origin

The origin read-only property of the URL interface returns a USVString containing the Unicode serialization of the origin of the represented URL. The exact structure varies depending on the type of URL:

For http or https URLs, the scheme followed by '://', followed by the domain, followed by ':', followed by the port (the default port, 80 and 443 respectively, if explicitly specified).
For file: URLs, the value is browser dependant.
for blob: URLs, the origin of the URL following blob: will be used, e.g "blob:https://mozilla.org%22 will be returned as "https://mozilla.org%22.

Note: This feature is available in Web Workers.
