URLPatterns

The URLPattern interface matches URLs or parts of URLs against a pattern. The pattern can contain capturing groups that extract parts of the matched URL.

let pattern1 = new URLPattern("https://example.com/books/:id");

// same as
let pattern2 = new URLPattern("/books/:id", "https://example.com");

// or
let pattern3 = new URLPattern({
  protocol: "https",
  hostname: "example.com",
  pathname: "/books/:id",
});

// or
let pattern4 = new URLPattern({
  pathname: "/books/:id",
  baseURL: "https://example.com",
});
