How to get an object inside an array that is inside an object in ember?

How would I 'get' the value of a property that is declared inside another property that is inside an array that is inside an object...

Here is an example:

App.THING = {
  id: 1,
  year: 2008,
  property: {
    id:1,
    location:"somewhere",
    assessments: [
      {
        assessment:{
          otherId: 1,
          value: 10,
        }
      }
    ]
  }
};

I want to get value. How would I get that value in the controller?

If you need more info, please let me know.
