url query paramter, path parameter 파싱하는 법

 const url = new URL(
   'http://example.com/path/index.html?message=hello&who=world'
 );
  
  console.log(url.searchParams.get('message')); // => 'hello'
  console.log(url.searchParams.get('missing')); // => null

  console.log(url.pathname); // => '/path/index.htm
