Yeah, you can write it in less than a minute:

const tryNew = (f, ...a) => {

  try {

   return new f(...a);

  } catch(x) {

   return undefined;

  }

 };

const myUrl = tryNew(URL, 'http://example.com/');

I don't get why JS devs like to whinge about the smallest things. And we get stuff like leftPad because of huge aversion to writing utility functions.
