Listen to what other said already. Once you are all ready to asynchronous,
you will come to something like this:
$http.get(...)
.then(function(response1) {
return $http.get(...);
})
.then(function(response2) {
return $http.get(...);
})
.then(function(response3) {
return $http.get(...);
})
...you can chain like that as long as you want.
There is no need to return only $http promises. You can return whatever you
want, including other promises... or just regular values.
You can also attach error handlers just like with try...catch synchronous
equivalent.
Do your async/promises/Q/$q homework and you will discover brand new world
:-)
