问题描述

具有

按照@Bergi的评论，我必须相应地更正我的答案，才能脱离反模式领域。

OK as per @Bergi's comment i have to correct my answer accordingly in order to take it off of anti-pattern realm.

function handleRejectedPromises(p){
  return p.then(v => ({status: "resolved", value: v}))
          .catch(x => ({status: "rejected", reason: x}));
}
var ps = [Promise.resolve(42), Promise.reject(37), Promise.resolve(23), Promise.resolve(11)];

Promise.all(ps.map(p => handleRejectedPromises(p)))
       .then(ra => ra.forEach(r => console.log(r)));
