= `object` A <<ref_value>> stores an instance of <<ref_object>> as the underlying representation for a JSON object. Instances of the <<ref_object>> type are associative containers holding key and value pairs, where the key is a <<ref_string_view>> and the mapped type is a <<ref_value>>. These containers are modelled after standard maps with these properties:

When parsing a JSON document, the type used to represent a number is not explicitly specified and must be determined from its value. In general, the parser will choose the best type which can accurately store the number as it appears in the document. Integers (i.e. numbers without decimals or exponents) that cannot be represented by `std::uint64_t` and `std::int64_t` will be represented as `double` to preserve their magnitude:

If the <<ref_value>> does not contain a number, or if the conversion is to an integer type `T` and the number cannot be represented exactly by `T`, the conversion will fail. Otherwise, the result is the number converted to `T` as-if by `static_cast`:
