age: 30,
sayHi() {
alert(this.name);
}
};

var admin = user;

Why does it still has reference to admin object.??

Answer 1

If you know the answer why are you asking?

Answer 2

User is just a variable. When you assign user to admin, it gets copied and admin has the same values and doesn't refer to user.
