I'm trying to make 3 API calls and then return an array of all the data. However, the console.log() (and therefore the function return) is empty as it's not waiting for the AJAX call to be resolved - but I can't do it in the loop as I need all the data.

```
let data = [];

parameters.forEach((parameter, index) => {
  return Ember.$.ajax(url).then((response) => {
    data.push({
      name: parameter.get('displayName'),
      color: parameter.get('color'),
      type: chart.get('chartType'),
      turboThreshold: 0,
      data: response.data
    });
  });
});

console.log(data);
return data;

```

I think that I can use Ember.RSVP.hash() for this but I can't seem to get it to work... can anyone point me in the right direction?
