Javascript JSON for each return only first object string

I'm trying to return only the first object's (that) string from an array. In my example when I loop it will return only the string from the third option.

I'd like for it to return only the second option e.g. the first object named that.

I thought it would work like this: 

data[i].that[0]

But it will return only the first letter.

var data = [{  
   "this":"first",
   "that":"second",
   "that":"third",
},{  
    "this":"first",
    "that":"second",
    "that":"third",
}]

data.forEach(function (value, i) {
     console.log(data[i].that)
});

Current:

third
third

Expected:

second
second

Your data is modeled wrong. You can't have duplicate keys in a JavaScript object.

You can however remodel it to the following, to achieve what you want (calling it with data[i].that[0]):

var data = [{  
   "this":"first",
   "that": ["second", "third"]
},{  
    "this":"first",
    "that":["second", "third"]
}]

data.forEach(function (value, i) {
     console.log(data[i].that[0])
});
