function ithrow() {
  throw Error("Can't do that");
}

p1 = new Promise(function(resolve) {
  resolve(ithrow())
});

p1.then(console.log.bind(console, 'p1'), console.warn.bind(console, 'p1'));

p2 = Promise.resolve(ithrow());
p2.then(console.log.bind(console, 'p2'), console.warn.bind(console, 'p2'));
