Nullable type: Language support, Compared with null pointers & Example

Nullable types are a feature of some programming languages which allow a value to be set to the special value NULL instead of the usual possible values of the data type. In statically typed languages, a nullable type is an option type,[citation needed] while in dynamically typed languages (where values have types, but variables do not), equivalent…
