javascript - 将 Promise 存储在异步函数的多个变量中

Question

是否可以使用 async/await 函数将已解决的 Promise 数据存储在多个变量中？

例如

const urls = [
    'https://jsonplaceholder.typicode.com/users',
    'https://jsonplaceholder.typicode.com/posts'
]

const getData = async function() {
    const Promises = urls.map(url => fetch(url))
    for await (let request of Promises) {
        const data = await request.json()
    }
}

getData()

// However, I want to store '/users' in 'const users', '/posts' in 'const posts' etc.

您似乎正在寻找

async function getData() {
    const promises = [
        'https://jsonplaceholder.typicode.com/users',
        'https://jsonplaceholder.typicode.com/posts'
    ].map(url =>
        fetch(url).then(request => request.json())
    );
    const [users, posts] = await Promise.all(promises);
    console.log(users, posts);
}
