問題
次のデータがあります。
{
"firstName": "John", "lastName": "Doe",
"address": { "streetAddress": "1 Main St.", "city": "New York", "state": "NY", "postalCode": "10099" }
},
{
"firstName": "Jane", "lastName": "Doe",
"address": { ... },
"contact": [ { "type": "email", "address": "jane.doe@contoso.com" } ]
}
これはどの種類のデータですか?
