How to wait for result of two promises, then do something?

Question

Well, subject. Can\'t figure out...

Condition: both promises start asynchronously and not one after another. Like this:

spashGoing.then(         


        

Answer 1

If WinJS promises are Promise/A+ promises

Promise.all([
    spashGoing.then(doSomethingForItself), 
    writingGoing.then(doSomethingForItself2)
]).then(function(results) {
    // do things with results
});
