-				Parse JSON text to a Variant (use [method typeof] to check if it is what you expect).
-				Be aware that the JSON specification does not define integer or float types, but only a number type. Therefore, parsing a JSON text will convert all numerical values to [float] types.
-				Note that JSON objects do not preserve key order like Godot dictionaries, thus you should not rely on keys being in a certain order if a dictionary is constructed from JSON. In contrast, JSON arrays retain the order of their elements:
