The example shows how `get_allocator()` is used to created `json` values.
```cpp
--8<-- "examples/get_allocator.cpp"
#include <iostream>
#include <nlohmann/json.hpp>
using json = nlohmann::json;
int main()
{
auto alloc = json::get_allocator();
using traits_t = std::allocator_traits<decltype(alloc)>;
json* j = traits_t::allocate(alloc, 1);
traits_t::construct(alloc, j, "Hello, world!");
std::cout << *j << std::endl;
traits_t::destroy(alloc, j);
traits_t::deallocate(alloc, j, 1);
}
```
Output:
```json
--8<-- "examples/get_allocator.output"
"Hello, world!"
```
