Building a dynamic object with inner objects in a loop

I'm reformatting an array of objects that i'm getting from an API endpoint into an object of objects with a key name. But I'm having trouble naming the first key and not just having it, 0, 1, etc...

I'm doing it like this:

    var objects = {};

        for (var i = 0; i < returnedObject.length; i++) {
          objects[i] = {
            time: returnedObject[i].time,
            date: returnedObject[i].date
          };
        }

results I'm getting:

    0: {
      time: "6:00 PM",
      date: "2015-10-30"
    },
    1: {
      time: "6:00 PM",
      date: "2015-10-30"
    },

Any ideas on how to name objects[i]? like this below?

    name1: {
      time: "6:00 PM",
      date: "2015-10-30"
    },
    name2: {
      time: "6:00 PM",
      date: "2015-10-30"
    }

Thanks for any help.

Also, if anyone knows where to look for good tutorials on advanced object editing/creating please share.

You can do this:

var objects = {};

for (var i = 0; i < returnedObject.length; i++) {
  var name = "name" + i.toString();
  objects[name] = {
    time: returnedObject[i].time,
    date: returnedObject[i].date
  };
}

Ahh, thank you Colin Marshall! I was able to take that and make it do exactly what I want and set the key name dynamically as well.

for (var i = 0; i < returnedObject.length; i++) {
      var name = returnedObject[i].home_team;
      objects[name] = {
        time: returnedObject[i].time,
        date: returnedObject[i].date
      };
    }
