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')
经过前面的题目解析，相信这道题可以很容易得出结果。
结果
'script start'
'async1 start'
'async2'
'promise1'
'script end'
'async1 end'
'promise2'
'setTimeout'
