iterate through objects and array javascript/angular

Question

I am trying to iterate an object that I get in Angular but I was unable to. In order to understand that I tried it simply using below code:

<script>
var x = {"data":['A','B','C']};
for(v in x) 
{
    alert(v[0]);
}   
</script>

The output of this is "d".How can I output "A"?

If you use this for loop, this is the syntax:

var x = {"data":['A','B','C']};
for(var key in x) 
{
    alert(key);    //data
    alert(x[key]); //A,B,C
}

This is plain JS though, no Angular.

You can add further if clauses to receive the first element like A, but make sure it doesn't error out on other properties of the object.
