map["M"] = "Stepp";
map.erase("Stepp");
map.erase("K");
map["J"] = "Cain";
map.erase("C, Lee");
cout << map << endl;

output
`{"J":"Cain", "C":"Lee", "M":"Sahami", "M":"Stepp"}` `{"C":"Lee", "J":"Cain", "M":"Stepp"}` `{"C":"Lee", "J":"Cain", "M":"Stepp", "M":"Sahami"}` `{"J":"Cain", "M":"Sahami"}` (order shuffled)
