【Promise第12题】下面代码的输出是什么？

const promise1 = new Promise((resolve, reject) => {
  setTimeout(() => {
    resolve("success");
    console.log("timer1");
  }, 1000);
  console.log("promise1里的内容");
});
const promise2 = promise1.then(() => {
  throw new Error("error!!!");
});
console.log("promise1", promise1);
console.log("promise2", promise2);
setTimeout(() => {
  console.log("timer2");
  console.log("promise1", promise1);
  console.log("promise2", promise2);
}, 2000);

和之前的题目比较类似，不做详细分析

'promise1里的内容'
'promise1' Promise{<pending>}
'promise2' Promise{<pending>}
'timer1'
test5.html:102 Uncaught (in promise) Error: error!!! at test.html:102
'timer2'
'promise1' Promise{<resolved>: "success"}
'promise2' Promise{<rejected>: Error: error!!!}
