JS中宏任务（setTimeout）和微任务（asyncawait）的执行顺序（一）titleasyncfunctionasync1(){console.log('async1start')awaitasync2()console.log('async1end')setTimeout(()=>{console.log('time1')},0)}asyncfunctionasync2(){console.log('async2start')setTimeout(()=>{console.log('time2')},0)}async1()console.log('start')setTimeout(()=>{console.log('time3')},0)(二)打印顺序async1startasync2startstartasync1endtime2time3time1（三）分析1.遇到await之后当前行的内容（不管是语句还是函数方法）；2、遇到await后非当前行的内容，在函数执行完后执行；3.宏任务队列会按照push进入的先后顺序依次打印输出；
