多个异步调用?

async.js 并行方法。它还将减少处理不同呼叫数据的负担。它也会这样做:

async.parallel([
    //different async calls you can add as many you want
    function(callback) {
        setTimeout(function() {
            callback(null, 'one');
        }, 200);
    },
    function(callback) {
        setTimeout(function() {
            callback(null, 'two');
        }, 100);
    }
],
// optional callback
function(err, results) {
    // the results array will equal ['one','two'] even though
    // the second function had a shorter timeout.
});

Promise.all :

async method() {
   return await Promise.all([
       call1()
       call2()
   ])
}
