您可以使用 Promise.all 方法let cleaRoom = function(){        return new Promise(function(resolve, reject){            resolve('room is cleaed')        })    }    let removeGarbage = function(message){        return new Promise(function(resolve, reject){            resolve(message + ' garbage is removed')        })    }    let wonIcecream = function(message){        return new Promise(function(resolve, reject){            resolve(message + ' won the icecream');        })    }Promise.all([cleaRoom(),removeGarbage(),wonIcecream()]).then(function(){    console.log('finished all');})這是我的示例小提琴以供參考。我錯(cuò)過了數(shù)組的循環(huán)，并且沒有關(guān)于如何計(jì)算的線索。提前致謝！
