constexpr value_t type() const noexcept;
Return the type of the JSON value as a value from the value_t enumeration.
the type of the JSON value
| Value type | return value |
|---|---|
#!json null | value_t::null |
| boolean | value_t::boolean |
| string | value_t::string |
| number (integer) | value_t::number_integer |
| number (unsigned integer) | value_t::number_unsigned |
| number (floating-point) | value_t::number_float |
| object | value_t::object |
| array | value_t::array |
| binary | value_t::binary |
| discarded | value_t::discarded |

Constant.
??? example
The following code exemplifies `type()` for all JSON types. ```cpp --8<-- "examples/type.cpp" ``` Output: ```json --8<-- "examples/type.output" ```
