 * The URLPattern API provides a web platform primitive for matching URLs based

 * The syntax is based on path-to-regexp. Wildcards, named capture groups,
 * regular groups, and group modifiers are all supported.
 *
 * ```ts
 * // Specify the pattern as structured data.
 * const pattern = new URLPattern({ pathname: "/users/:user" });
 * const match = pattern.exec("/users/joe");
 * console.log(match.pathname.groups.user); // joe
 * ```
 *
 * ```ts
 * // Specify a fully qualified string pattern.
 * const pattern = new URLPattern("https://example.com/books/:id");
 * console.log(pattern.test("https://example.com/books/123")); // true
 * console.log(pattern.test("https://deno.land/books/123")); // false
 * ```
 *
 * ```ts
 * // Specify a relative string pattern with a base URL.
 * const pattern = new URLPattern("/:article", "https://blog.example.com");
 * console.log(pattern.test("https://blog.example.com/article")); // true
 * console.log(pattern.test("https://blog.example.com/article/123")); // false
