in the videos we were using close(database) quite a bit but here its not working for the challenge, I dont understand the difference between close(database) and database.close(). Are they not interchangeable?
/* Add your code here!
* Assume you already have a variable named 'database'.
*/
database.setTransactionSuccessful();
database.endTransaction();
close(database);

The short answer: No, they aren't interchangeable.
close(database)
is a method that was created during the videos, and it specific only to that file being used in the video (and you files if you are following along).
I'm not sure which video that method was created in, but you can see the it here at 1:55. It is a private method with the purpose of executing database.close()
which is a method called on the instance of the database.
In the challenge, there is no close
method, so the challenge has no idea what you are trying to do. All the Challenge knows is that you are trying to call a method that does not exist (in its scope). So, you need to call the instance method on the object using dot notation.
Hopefully that helps clear it up. :)
Keep Coding!
