D. userInformation("email") 에서 () 를 [] 로 바꿔줘야 실행이 된다. -> userInformation["email"]
const userInformation = {
"id" : "user-01",
"email" : "user01@universalcontainers.demo",
"age" : 25
}
//console.log(userInformation.get("email"));
//console.log(userInformation(email));
console.log(userInformation.email);
console.log(userInformation["email"]);
