【Promise第34题】下面代码的输出是什么?
js
async function async1() { console.log("async1 start"); await async2(); console.log("async1 end"); }
async function async2() { console.log("async2"); }
console.log("script start");
setTimeout(function() { console.log("setTimeout"); }, 0);
async1();
new Promise(function(resolve) { console.log("promise1"); resolve(); }).then(function() { console.log("promise2"); }); console.log('script end')
## 参考答案:
