Similar to map, mapAsArray can be used to serialize a map-like collection where the key is
contained in the 'value object'. Example: consider Map<id: number, customer: Customer> where the
Customer object has the id stored on itself. mapAsArray stores all values from the map into an
array which is serialized. Deserialization returns a ES6 Map or plain object object where the
keyPropertyName of each object is used for keys. For ES6 maps this has the benefit of being
allowed to have non-string keys in the map. The serialized json also may be slightly more
compact.
