handling exceptions thrown in onResolved

exception-in-on-resolved.js

function p() {
  return new Promise(function(resolve) {
    setTimeout(() => resolve(5), 200);
  });
}

var x = 0;

function throwSomething() {
  console.log('Throwing...', ++x);
  throw x;
}

function report(e) {
  console.log('Caught:', e);
}

// this will make `report` catch the exception thrown in onResolved
p().then(throwSomething).catch(report);

// this won't
p().then(throwSomething, report);
