This code registers an 'unhandledRejection' handler, then calls a function that returns a rejected Promise without a .catch(). What gets logged, in order?

process.on("unhandledRejection", (reason) => {
  console.log("Caught unhandled rejection:", reason.message);
});

function fail() {
  return Promise.reject(new Error("boom"));
}

fail();

console.log("sync done");
