Properties are key/value pairs which are assigned to a thing
. The collection itself is also a thing
to which properties can be assigned.
For example: .answer = 42;
creates a property answer
with value 42
and the property will be assigned to the collection.
The key
of a property must be of type string. If the key is not a valid name, then the property can be set by using
the square bracket [..]
notation or the set(..) / get(..) functions can be used.
