Using Angular's $q.all with codependent promises

Second promise needs result of the first promise as a parameter. I have seen an example of solving this problem with ES6 promises. 

firstThingAsync()  
  .then(function(result1) {
    return Promise.all([Promise.resolve(result1), secondThingAsync(result1)]); 
  })
  .then(function(result1, result2) {
    // do something with result1 and result2
  })
  .catch(function(err){ /* ... */ });

But I am not sure what $q function has similar behavior to Promise.resolve. Any ideas?

In Angular 1.4 you can use $q.resolve(result1).

Source: Angular 1.4 $q.resolve docs.

In older versions you can use $q.defer().resolve(result1).

Source: Angular 1.3 Deferred API docs.
