reverse order of serialization

[CDitzel]

why is the snippet

json j; j["pi"] = 3.141; j["happy"] = true; std::ofstream ofs{ "test.json" }; ofs << j << std::endl;

rsulting in an output like the following

{
"happy": true,
"pi": 3.141
}

it should be the other way around should it not? What am I missing here?
