13,758 PointsI understand your confusion. Let me tyry to explain:
- The property 'breed' is already declared in the object 'ernie'
- now you create a variable called 'prop' with a string value of 'breed'
- instead of calling the method as ernie['breed'] you can now also call it using ernie[prop] because the variable prop is equal to the string 'breed' (prop = 'breed')
Hope this clarifies it a bit.

231,275 PointsDid you try out the examples yourself? A bit of experimentation might be much more valuable than additional explanations.
And the property in the example was "breed". We probably should not give ernie any "beer", he's only 1 year old!
