javascript - 如果我不想等待 2 个方法而是等待两个方法都完成怎么办

Question

我有 2 个异步方法，如下所示。如果我希望两者同时运行但等待两者完成然后继续，该怎么办？

exports.get = async id => {
    const part1 = await context.get(id);
    const part2 = await context.get2(id);
    //run both asynchronously, but wait until both are finished
};

这是Promise.all的定义

exports.get = async id => {
    const [part1, part2] = await Promise.all([context.get(id), context.get2(id)]);
};
