Javascript getting data undefined on console when it shouldn't

I have this data:

{
   "id":"01",
   "new":0,
   "closed":0,
   "locked":0,
   "subhere":[
      {
         "id":"123",
         "subname":"somename"
      }

...etc...

In the console log I'm getting this to show (See comments):

console.log('Level 1 ID: ' + obj.id); //This works!
console.log('Level 1 Closed ' + obj.closed); //This works!
console.log('Level 1 Locked ' + obj.locked); //This works!
console.log('Level 2 Subhere ID ' + obj.subhere.id); //This returns Undefined!

The last console.log is giving me Undefined but I don't see what the problem is...why?

Any ideas on why I'm getting Undefined on the last one?

Since obj.subhere is an array so obj.subhere.id will be undefined. You need to get array element first which is the object.

console.log('Level 2 Subhere ID ' + obj.subhere[0].id)
//---------------------------------------------^^^----


var obj = {
  "id": "01",
  "new": 0,
  "closed": 0,
  "locked": 0,
  "subhere": [{
    "id": "123",
    "subname": "somename"
  }]
};

console.log('Level 2 Subhere ID ' + obj.subhere[0].id)

You should use this

 console.log('Level 2 Subhere ID ' + obj.subhere[0].id);

subhere is an array - and you're referring to it as an object.

Hence it should be rather:

console.log(obj.subhere[0].id);
