 JSON values can be created from many literals and variable types:
 
-| JSON type | literal/variable types |
-| --------- | ---------------------- |
-| none      | `nullptr` literal, `nullptr_t` type, no value |
-| string    | string literal, `char*` type, `std::string` type, `std::string&&` rvalue reference, `JSON::string_t` type |
-| number (integer) | integer literal, `int` type, `JSON_number_t` type |
-| number (floating point) | floating point literal, `double` type, `JSON::number_float_t` type |
-| array | initializer list whose elements are `JSON` values (or can be translated into `JSON` values using the rules above), `std::vector<JSON>` type, `JSON::array_t` type |
-| object | initializer list whose elements are pairs of a string literal and a `JSON` value (or can be translated into `JSON` values using the rules above), `std::map<std::string, JSON>` type, `JSON::object_t` type |
