There is no way to store an empty object/array/null value. | |
There are also no actual arrays. Array values get stored as objects with integer keys. | |
(If all keys are integers, it will be returned as an array.) | |
Basically, it's one giant tree of hashes with string keys. | |
Simply write a value to any location, and the intermediary locations will automatically come into existance. | |
