使用异步iterable链接承诺

const upload = ({name}) => 
    new Promise((resolve) => 
        setTimeout(() => resolve(`Response for upload of: ${name}`), 1000))

const asyncIter = (arr) => (async function*() { for (let i of arr) yield i() }())

const uploadInSeries = async (arr) => {
    const iter = asyncIter(arr.map((i) => () => upload(i)))
    for await(let response of iter) {
        console.log(response)
    }
}

const projects = [{ name: "P1" }, { name: "P2" }, { name: "P3" }]
uploadInSeries(projects)
