In the code below we have an object literal called user tha has two properties: name and age. If we try to create a newUser starting from user and, after that, we try to change the name, you'll notice that even the original user has been modified. How can we modify the name of newUser without changing the name of user?
let user = { name: "Cosimo", age: 30, };
let newUser = user;
newUser.name = "Paolo";
console.log(newUser); console.log(user);
Suggestion
Try to use a for in loop, as it showed in the video lessons.
You would need a new copy of the user object.
