Iterate over indefinite array of deferred items

Question

Say I have a very long list where each element requires an asynchronous call to fetch. I would like to write an API on top of that list so that a consumer can simply call \"

You can't have such syntax because it would just go into infinite busy loop.

There is a common promise idiom to do this:

var array = [process1AndFetch2, ...]

array.reduce(function(a, b) {
    return a.then(process).then(b);
}, array.shift()()).then(function(){
    //All processed
});
