The following code shows an example for the `array` function.
```cpp
--8<-- "examples/array.cpp"
#include <iostream>
#include <nlohmann/json.hpp>
using json = nlohmann::json;
int main()
{
// create JSON arrays
json j_no_init_list = json::array();
json j_empty_init_list = json::array({});
json j_nonempty_init_list = json::array({1, 2, 3, 4});
json j_list_of_pairs = json::array({ {"one", 1}, {"two", 2} });
// serialize the JSON arrays
std::cout << j_no_init_list << '\n';
std::cout << j_empty_init_list << '\n';
std::cout << j_nonempty_init_list << '\n';
std::cout << j_list_of_pairs << '\n';
}
```
Output:
```json

[1,2,3,4]
