URL: search property

The search property of the URL interface is a search string, also called a query string, that is a string containing a '?' followed by the parameters of the URL.

Modern browsers provide the URL.searchParams property to make it easy to parse out the parameters from the query string.

Note: This feature is available in Web Workers
