You should take a look at this previous challenge:
There are important lessons within the challenge that you posted:
Whenever you see [ ], you’re working with an array, and whenever you see {property: value}, you’re working with an object (or JSON, but that comes later).
In previous lessons, you would assign arrays and objects to variables. BUT you can assign those values to just about anywhere. An object can go inside another object, an array can go inside an object, an object can go inside an array that’s inside an array that’s inside an object and it can go on and on and on.
For the purpose of this challenge, it’s telling you that there’s already an object {} inside an array []. It just wants you to add another object {} inside that same array.
@ardn-jordan all you need, is to add a comma between the 2 brackets (see pic).
The reading stated that UNLESS it is the last “record”
in the array, place a comma between records. Hope this helps
