Vuejs array push

I'm receiving array of objects from backend in below format. I am trying to get this data and push it into a JavaScript array so that I can use them later on based on my needs.

[
    {
    id: 1,
    name: "Dr. Darrin Frami III",
    email: "[email protected]",
    address: "42568 Cameron Cove Fritschborough, MA 86432-0749",

    },
]

Here is my vuejs code: 

<script>
    export default {
      data(){
        return {
          fakeUsers: [],
          fakeUser: {id: '', name: '', email: ''},
        } 
      },
      methods:{

      },
        mounted() {
            var route = '/get-users';
            this.$http.get(route).then((response)=>{
              for (var i = 0; i < response.data.length; i++) {
                 this.fakeUser.id = response.data[i].id;
                 this.fakeUser.name = response.data[i].name;
                 this.fakeUser.email = response.data[i].email;
                 this.fakeUsers.push(this.fakeUser);
              }

            });
            console.log(this.fakeUsers);
            console.log(this.fakeUsers[0]);
        }
    }
</script>

the vue-dev tool result:

enter image description here

Output of the line console.log(this.fakeUsers); is [__ob__: Observer]. Shouldn't it print something like [Array[10]]?

Output of the line console.log(this.fakeUsers[0]); is undefined, and I can't figure out why.

$http() creates an async ajax call, so the code in then() is executed after the console command after it.

Simple solution: put the console commands into the function in .then() as well.
