 * - Building routers for web applications
 * - Pattern-matching URLs for middleware
 * - Extracting parameters from URL paths
 * - URL-based feature toggles
 * - Routing in serverless and edge functions
 *
 * The syntax is based on path-to-regexp, supporting wildcards, named capture groups,
 * regular groups, and group modifiers - similar to Express.js route patterns.
 *
 * @example
 * ```ts
 * // Basic routing with URLPattern (similar to Express.js)
 * const routes = [
 *   new URLPattern({ pathname: "/users" }),
 *   new URLPattern({ pathname: "/users/:id" }),
 *   new URLPattern({ pathname: "/products/:category/:id?" }),

 *
 * // Check incoming request against routes
 * function handleRequest(req: Request) {
 *   const url = new URL(req.url);
 *
 *   for (const route of routes) {
 *     const match = route.exec(url);
 *     if (match) {

 * @example
 * ```ts
 * // Matching different URL parts
