一、来一道字节的面试题,分析一下输出什么
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');
