如下打印结果是什么 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');
