How to combine multiple callbacks? Specifically for BingMap module loading

Question

I have the following code that I am looking to simplify:

var MM = Microsoft.Maps;
MM.loadModule("MM.Clustering", function () { 
    MM.loadModule("HtmlPushpinLayerModule", function () { 
        // Do actual work
    });
});

Is it possible to combine these into something like (pseudocode):

MM.loadModule("MM.Clustering") && MM.loadModule("HtmlPushpinLayerModule"), function() {
    // Do actual work
});

You can use Promises and use Promise#all for waiting for the callbacks.

You can see something like this in this question: Microsoft bing maps api and loading modules issue

Unfortunately can't use this approach for Internet Explorer 11, since it doesn't support promises. – AngryHacker Dec 20 '17 at 22:30
You can use some polyfill for IE 11 to make compatible with most recent browsers. – Ciro Spaciari Dec 21 '17 at 10:19
